Evidence suggests that climate change will create uncertain regional agricultural production stability in the coming decades. This research investigated the impact of climate change on hydrology and sugar beet yield as one of the main crops in the Urmia lake basin using the Soil and Water Assessment Tool (SWAT). To address this, a baseline SWAT model was setup for 1986-2014. Afterward, the output was calibrated (1989-2004) and validated (2005-2014) in the SWAT-CUP software using the SUFI2 algorithm to simulate streamflow of 23 gauging stations and crop yield. The Nash-Sutcliffe efficiency was 0.43 and 0.53 for calibration and validation periods, sequentially. The Percent Bias was 45% and 16% for calibration and validation periods, respectively. As well as the agreement indices of 0.71 and the little Percent Bias (-6% to 10%) for crop production, verified the model's efficiency. The next step was downscaling and bias-correction of the precipitation and temperature data received from 3 climate models, namely GFDL, HadGEM2, and IPSL under RCP4.5 and RCP8.5 using CCT program. Then, the downscaled data were fed to SWAT, and Finally, hydrological fluxes and sugar beet yield were estimated for 2021-2050. Despite a dispersion of precipitation changes ranging from -12% to +35% in most scenarios, results highlight the pivotal role that the warmer temperature (+2.7°C) increases evaporation, resulting in sharpened pressure on water resources and runoff, especially, at the beginning of crop growth season. Finally, the negative impacts on crop productivity (-45%) is not unexpected. This means that sugar beet may suffer from climate change impacts, and the production of this plant will change over the next period in this region.

Along with the development of cities and increasing population, many challenges have been created, the most important of which is urban transportation. The inability of traditional urban management to address this challenge has led to some approaches, including intelligent transportation. Adopting and implementing such an approach in metropolitan areas requires a change in management approach, of which integrated urban management is known as the most important. The purpose of this study is to investigate the status of integrated urban management and then its impact on the realization of intelligent transportation in the city of Zahedan. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The validity of the instrument and its reliability was confirmed by Cronbach's alpha greater than 0.70. The statistical population of the study is urban experts in Zahedan. The sample size was set at 100 people. The result of the one-sample t-test shows that the variables of integrated urban management are significant at the level of less than 0.05. From the statistical point of view, the 7 variables of good governance, synergy, unity of urban command, context, interaction, organizational structure, and systemic perspective are not in a good situation and these conditions have caused the integrated urban management index in Zahedan to not have favorable conditions. Also, the significance of the test shows that the 5 variables of intelligent transportation, namely intelligent monitoring, intelligent payment, intelligent violation registration, intelligent information, and mechanized fleet management are significant at the level of less than 0.05. Significantly, it indicates the unfavorable situation of the intelligent transportation index in Zahedan. Regression showed that integrated urban management variables can be more than 68% effective in the realization of intelligent transportation and 32% are dependent on other factors. The variable of good governance with 12% and then the systemic perspective with 11%, has the greatest impact in this regard.

Every city, according to its assets, seeks to develop and consolidate its position at national, regional and international levels, since city branding is one of the most dynamic activities in the field of policy making in the present era, which plays an important role in sustainable development of the region and due to the increasing growth of city development in cultural, economic, environmental and etc. There is a need for a targeted and comprehensive planning to keep pace with sustainable development. Considering the development components and its impact on city branding indicators, this research deals to improve the development and city branding status in the province by examining their situation. The statistical population of this study consisted of two groups: the first group was experts with knowledge that the number of people in this population is uncertain and the sample size is 60 people. The second group consists of policy-making and senior managers, employees with higher education in Bushehr province with 37,751 people and the sample size has been determined by using The Cochran formula of 382 people. Data were collected through 4 questionnaires confirming their validity and reliability. To measure structures and relationships between them, structural equations with partial least squares approach and SMART PLS software have been used. The results indicate that at 95% confidence level, the city branding policy variable has a positive and significant relationship with the development model. Therefore, it is suggested that the policy makers and urban management should plan for the urban branding of the province and improve the development dimensions according to the relationship of the urban branding policy with the dimensions of development.

As cities become more physically in structure and demographically wider, the rate of crises is also increasing consequently, and cities become more vulnerable to natural disasters for a variety of reasons, including economic and cultural poverty, fault alignment and non-compliance to regulations of earthquake-related issues. What matters is the level of community's preparedness and the degree of vulnerability of the city and its residents, which can be reduced to the lowest level if properly planned and principle policies are adopted. In this research, considering the high potential of Sanandaj in terms of seismicity and the existence of many faults in the vicinity and around of the city, it is tried to gain an authentic understanding of the subject with identifying the factors affecting the earthquake and combining indicators using the Classification Tree Analysis (CTA) model. The results indicate that a large area of the city is in the category of moderate to high vulnerability.52% is in the middle vulnerability category,16.5% is in the high vulnerability category and 1% of the city is considered to be in the very high vulnerability category, which exactly matches the same marginal, old and densely populated neighborhoods. This situation does not render a proper structure and needs more consideration in prospective development plans.

Population growth and the need for economic and social services have accelerated the demands for land and its manipulations over the recent decades. The contribution of policies and interventions of different stakeholders in land change is not adequately addressed in previous studies. This research, therefore, aims to examine the role of key stakeholders, and their policies in land-use change in the study area. In doing so a total number of 20 interviews with senior experts and informants from 13 local organizations were conducted to collect qualitative data on the form, process and cause of land-use change in the area. Atlasti software was used to analysis the interviews' data. Furthermore, Social Networks Analysis (SNA) and questionnaires were used to map the trust among the stakeholders and also the role of their policies and program on land-use changes from the perspective of other stakeholders. The results show that the policies and interventions of the municipality are playing the most significant role in land-use change via disregarding and violations of roles and related for individual illegal benefits. Additionally, departments of agriculture, rural councils are among the most trusted agents in land use governance and management. Furthermore, water shortage was the most important reason pointed out by the many interviewees for conversion of farmlands to other uses. A part from water shortage, some other reasons such as: lack of governmental support for farming, strict official constraints and difficulties in providing amenities for gardens, expensive agricultural inputs, land price increase, immigration, corruptions in local organization are identified as drivers of rural land-use change.

Today, attention to the tourism of historical contexts has been recognized as very important in order to promote socio-economic progress and to recognize the historical values ​​and cultural identity of each region. Therefore, this study was written with the aim of identifying the causal pattern of tourism promotion criteria in the historical context of Tabriz. The research is applied in terms of purpose and descriptive-analytical in terms of method. The statistical population of the study consisted of experts in the field of research, 15 of whom were selected through targeted sampling. The collection of required information in this research has been done using library and field methods and Fuzzy DEMATEL method has been used to analyze the research data. The results of this study showed that among the identified criteria, the primary element criterion was identified as the most effective criterion and also as the most important criterion for promoting tourism in the historical context of Tabriz. Other results of this study include the causal model of each of the sub-criteria, among the sub-criteria of primary elements, historical criterion, among the sub-criteria related to secondary elements, accommodation facilities, and among the sub-criteria of favorable tourism space. They were identified as the most influential sub-criteria.

Today, fine dust and dust storms have become one of the important issues and problems of Iran and other regions of the world. This study is conducted to identify synoptic patterns of the dust storms in Ardabil Province (Iran) and monitor the origin and pathway of its places. The studied period is 34 years (1979-2013). The data used in this work are from synoptic stations of Ardabil province and the NASA’s upper atmosphere database. To achieve the goals of the study, the Environment to Circulation, Hierarchical Clustering Methods, and HYSPLIT model were used. According to the results, three patterns of geopotential height at 500 hPa levels were identified. Pattern No. 1 and 2 are almost similar to each other and represent the occurrence of a deep trough that formed from Central Europe and extended to the middle of the Red Sea. Based on these patterns, the study area is located in the East of this trough. The third pattern represents the occurrence of cut-of-low pressure blocking over the Black Sea and adjacent areas and placement of Ardabil province in the East trough of the formed blocking. The origin of dust in patterns 1 and 2 is the Eastern regions of Iraq and West of Iran while in pattern 3 is at 500 hPa level of the central areas of Iraq and at pressure levels of 850 and 1000 hPa of the central regions of Syria.

This study examines the criteria for sustainable urban development management in thriving cities around metropolises. Based on the content analysis method in examining the theories in this field, a special conceptual model has been developed that presents the role of various indicators affecting the management of sustainable urban development in thriving cities. Also, based on the case study method, the city of Lavasan was selected as a case study to provide a realistic understanding of the role of various components on sustainable urban management in thriving cities around metropolises. The research method was based on quantitative and qualitative methods. Based on the field visit, initial discussions and conceptual model of purposeful questionnaires were prepared. SPSS21 and Smart-PLS statistical techniques were used to find the relationships of the variables and to analyze the information of the questionnaires. 376 questionnaires have been analyzed in relation to the components of sustainable urban development management. The results of the analysis show that the components affecting the management of sustainable urban development in Lavasan can be in physical-spatial dimensions, quality of life, intelligent management, justice and examined equality, governance, and optimal legislation. The results also show that the physical-spatial factor is the most important effective criterion. Also, the path of factor analysis shows that achieving urban prosperity in cities around metropolises begins with smart urban management, governance and appropriate legislation in the field of physical infrastructure. Space and quality of life infrastructure lead to the spread of justice and equality in the city and ultimately lead to urban prosperity.

The Islamic City Councils as an important element of the urban management system as an institution, policymaker, decision maker, and legislator at the local level, have to be fully operational in order to fulfill their role of policymaking and oversight over all matters to be able to carry out policy and oversight tasks in all areas of the city and local organizations concerned. Therefore, the purpose of this study is to measure the effectiveness of city council performance in improving the process of sustainable urban management and development from the perspective of citizens in Tabriz metropolis. This study is practical in terms of purpose and descriptive-analytical in terms of nature and method and document studies and field surveys were used to collect data. The statistical population of the study is all citizens and residents over 18 years of Tabriz metropolis. According to the 2015 census, this city had a population of 1558693 people and 497898 households. Cochran formula was used to determine the number of samples from 327 subjects were selected. The data for the analysis of quantitative methods, descriptive and inferential statistics (one-sample t, Kruskal-Wallis ANOVA, regression and path analysis) were used. The results showed that the average index of the performance of Islamic councils is 2.76 and its T-statistic is -6.59, which shows the unfavorable performance of the city council and the performance of the Islamic Council of this city in district 9 (with an average of 248.80). district 8 (with an average of 239.38) and district 2 (with an average of 204.33) have been evaluated favorably compared to other regions. Also, the average of all indicators of empowerment of Islamic city councils in the field of empowerment of Islamic councils is lower than numerical utility 3 and their t-statistic is negatively estimated. Finally, the performance of the Islamic councils in the economic dimension (employment, income and investment) has had the greatest effect with an overall effect of 0.608 and the least effect in the physical dimension with an overall effect of 0.210 in the realization of sustainable development.

Flood is one of the most destructive natural phenomena. Every year it brings extensive losses to the country’s financial and human resources. In our country, major parts of Iran’s provinces are always at risk of flooding. The Gorgan and Atrak catchments have also become more important, as several floods have occurred in Golestan province in recent years, causing many deaths and economic losses. The purpose of this study was to investigate the synoptic and thermodynamic conditions of the March 2019 flood event in Golestan province in order to atmospheric system that lead to such floods. This study includes statistical analysis of provincial stations (Gorgan, Gonbadkavus, Aliabadkatol, Hashemabad, Kalale, Maravetape and Bandaretokman), calculating of the return period of precipitation during the available statistical period of each station, analysis of synoptic maps on the day of the flood event, the analysis of satellite images of the days involved in the flood, and calculation of instability indices of the Gorgans’s station. Statistical results showed that Gorgan and Gonbadkavus stations, with the highest amount of rainfall in March 2019, had a return period with 800 and 400 years respectively. Also the highest amount index of Gorgan with values of K=26°c, PW= 0.27 cm and TT= 48 was obtained with high relative humidity (about 80%). The analysis of the synoptic maps showed the severe sea level pressure and mid- level height drop with a deep trough in the study area, which led to extreme rainfall.

Access, plays an important role in rural development as there is a meaningful relationship between rural development and access to infrastructure services. Villages that have less access to essential services, especially transport, faced with a lot of structural and socio-economic constraints, which are obstacles to sustainable rural development. The present study seeks to examine the accessibility and the factors affecting it. Accordingly, it is considered with descriptive-analytic research method. The statistical population of the study, consisted of villages in the central District of Tabriz County (52 villages) that there needed data were gathered from rural municipals. After validity and reliability of the research, in order to evaluate accessibility, we used the Dematel technique and ANP, then to assess the role of different elements in accessibility of rural areas, we used SEM in Amos software. Initial results of Rural Accessibility Survey showed that the Mayan Sefli village had the highest accessibility and the final result of the research are determining the role of factors in rural accessibility based on factors such as distance from the city, service centers and social status of the village are more effective than other factors in accessibility.

Tourism is now considered as one of the most important income industries of the world. Tourism as one of the main and basic approaches can be used in solving problems resulted from unemployment problems and downturn in different countries and the twenty-year vision of Iran specially consider tourism and attracting tourists. The huge volume of the tourists in the world are religious tourists and most of these religious tourists choose Mehran international border for entry and exit from Iran for doing pilgrimage and their religious affairs due to being safe and vicinity to The Holy of Holies in Iraq. This research aims at designing and explaining religious tourism model in Mehran International Border. Having determining the sample size qualitatively via snowball method, 14 experts of religious tourism including academics and trustees of religious tourism were recognized and they were interviewed directly and the research findings showed that religious tourism pattern in Mehran International Border has six main components including casual conditions (religious and tribal communities, provincial infrastructures, common border of Iraq and vicinity to The Holy of Holies, advertisements) categories (tourism and its subcategories, religious places in Iran and Iraq, security) grounds (commercial free zone in Mehran welfare and health services, economic part of religious tourism), interferer factors (political factors, conveying affairs to non-governmental sector, weather changes), strategies (cooperating with educational centers and universities, increasing governmental investing, using capacities of religious days) consequences & results (income and creating jobs, people’s persistence in border and non-immigration, cultural development of province, destruction of environmental, road and jungles of province) which could be introduced as a proper pattern for religious tourism in Mehran International Border according to the opinion of experts.

Old trees as the most important genetic reserves of the country have great importance and value in various aspects of ecology, forest restoration management, ecotourism and even history. In this research, after identification of the old trees in the forests of Ilam province, their morphological characteristics including DBH, trunk height, total height, crown length, min & max crown diameter, crown health, crown firmness, crown symmetry, Trunk health and trunk shape were examined. The selection of old trees was based on DBH criterion. After the forest survey, 43 old trees including 5 Petrocarya fraxinifolia, 5 Ulmus glabra, 11 Fraxinus rotundifolia, 3 Celtis caucasica, 4 Platanus orientalis, 4 Ficus carica, 7 Olea europea and 4 Cupressus sempervirens were identified. The results showed that among single-stranded trees, P. orientalis had the highest mean DBH (171 cm), total height (15.8 m) and trunk height (6 m), and among multi-stranded trees O. europea had the highest mean DBH (260 cm). P. fraxinifolia and U. glabra had the highest mean of crown length (11 m) and F. rotundifolia had the highest crown area (195 m2). The highest percentage of single-trunks belonged to the P. fraxinifolia (80%) and C. caucasica (67%). The highest percentage of healthy trunks belonged to C. sempervirens (50%) and O. europea (50%) and the highest percentage of healthy crowns belonged to P. fraxinifolia (100%), C. caucasica (100%), P. orientalis (100%), O. europea (100%) and F. carica (100%). The highest percentage of crown symmetry was belonged to C. caucasica (100%) and the highest percentage of crown freshness was belonged to P. fraxinifolia (100%), F. rotundifolia (100%), C. caucasica (100%), P. orientalis (100%), O. europea (100%) and F. carica (100%). Based on the desirable morphological characteristics of old trees, it is possible to help the strengthen and restoration of Zagros forests by producing resistant seedlings from their seeds.

Increasing energy demand and environmental problems caused by the consumption of fossil fuels have made the use of passive solar energy methods more necessary, especially in commercial centers. On the other hand, the growth of science and technology in the world and the use of intelligent systems in buildings, has led to the completion of common methods. The purpose of this study is to investigate the role of the side wall of atriums and building intelligence in optimizing energy consumption in commercial centers of Tehran. Due to its nature, the research method is simulation with a case study and analytical approach and in terms of application type. In this research, first, the typology of the building form is introduced and the basic model is selected, and after selecting the design-builder software, validation and simulation of energy consumption in different scenarios are performed to determine the reduction of energy consumption in different situations. This research, which is taken from a doctoral dissertation, shows that the most optimal commercial centers in terms of reducing energy consumption in the climate of Central Tehran are related to atrium buildings without side walls. Also, the installation of smart awnings and light sensors at a control temperature of 22 degrees has significantly reduced energy consumption in these buildings.

The importance of studying development in the field of child psychology is crystallized. On the other hand, cognitive development is a source of awareness in the field of children's development and has a double effect on the process of wayfinding children. Paying attention to this in urban spaces can make it easier for children to successfully wayfinding. The purpose of this study is to develop factors affecting the ease of wayfinding children in urban spaces with emphasis on cognitive abilities. The research method is applied in the present study. In this regard, in order to collect data, field observations, questionnaires and site visits have been used. The sampling method is random using Cochran's formula and the questionnaire was completed by 106 children in the age range of 10-12 years and 106 children in the age range of 12-14 years. Data analysis to analyze the routing pattern of children affected by cognitive development in Lashgar neighborhood has been calculated quantitatively by factor analysis using LISREL software. In data analysis to evaluate the relationship between wayfinding and cognitive development after data collection, the data were analyzed by statistical methods of Ti-dependent test, Kolmogorov-Smirnov hypothesis test. Based on the analysis of cognitive abilities in the navigation process of children, the results indicate that the elements of the guide and used in navigation are different in two age groups, and the age group of 12-14 years has an analytical mind, and in contrast to the group of 10-12 years, it is searching and Paying attention to secrecy determines the path. Children in the second age range mostly mentioned the color of the facades, the shape of the building and the buildings that have a distinctive form and function, also the children in the first age range pointed to the distinctive signs that have a distinct body compared to other buildings in the neighborhood.

Rural management has always undergone various changes. Today, this pillar is the responsibility of the rural municipality Foundation. The purpose of forming this institution is to have a strong executive force in order to develop rural areas. rural municipality, as the executor of village programs and projects, has an important role in reducing urban and rural inequalities and improving the development of the village. Determining the degree of success of rural municipality in performing tasks is possible when its performance is carefully measured. The purpose of this study is to assess the performance of rural municipality Foundation in terms of economic, social and environmental indicators in rural areas of Sarbisheh. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The statistical population of the study consisted of heads of households (1931 households) in 30 villages with rural areas. The sample size at the level of heads of households was calculated using the Cochran's formula of 320 people. The result of one-sample t-test showed that the best performance of rural areas is significantly less than 0.05 in terms of social indicators with an average of 3.78. Also, a significant difference was observed between the studied villages in the field of social indicators with a significant level (0.008), economic indicators with a significant level equal to (0.004) and environmental-physical indicators with a significant level (0.047). In terms of social performance, Dehneh Chah village with an average of 4.43, in terms of economic and environmental performance, Baghestan village with an average of 3.90 and 4.16 are in first place. The study of paired t-test with a significance level of less than 0.05 and an average difference of (-1.271) indicates that the situation of rural development indicators has become more appropriate after the establishment of the rural municipality Foundation.

Vitality is one of the main components in design, but it is a complex and multifaceted concept that overlaps in its physical, social and economic dimensions. Therefore, in this paper, according to the theoretical vacuum of this concept in architecture and considering its interdisciplinary nature, using the model of various types of communication and types of vitality, the fields of psychology and sociology were selected for comparative study of vitality. Then, by using the comparative method by juxtaposing the differences and similarities of vitality in the field of psychology and sociology with definitions in architecture and urban planning, as well as examining the difference between vitality and other similar concepts in architecture and urban planning, including quality. Life, viability, and sustainability were ultimately represented by the definition of vitality and the model of environmental vitality. Therefore, the present study was performed with interpretive paradigm, qualitative approach, comparative method and logic of deductive reasoning, which is explained in terms of theoretical purpose and type of results. The purpose of this study is to answer questions about the definition of environmental vitality, the appropriate approach to research on vitality, the appropriate scale of vitality research, the factors affecting environmental vitality and its evaluation methods.

Geomorphology is related to the processes and forms of the earth's surface, and any human activity, including the construction of bridges, leads to quantitative and qualitative changes in the movement and displacement of materials and kinetic energy and affects the geomorphic system, is the concern and involvement of geomorphologists. Geomorphology, as a systematic science can also study and explain the environmental realities that have been objectified in the form of processes and forms in nature, and introduce their results and output spatially in the form of maps and models. The type of research is applied and the research method is descriptive-analytical and based on the results of the Ph.D. Thesis entitled "Geomorphological modeling of the construction of bridges in urban floodways (Case study: Tehran metropolis)". The results indicate the capability and application of geomorphology in modeling and optimal location and construction of bridges, in order to create more security and welfare of citizens, reduce costs and prevent financial and human losses due to the destruction and improper location of such structures in an urban floodway- river valleys and other natural environments. Also, this study, while enriching the literature of the field in question, has studied, explained, and conceptually modeled the role and application of geomorphology in the optimal location and construction of bridges in urban issues. 

In relation to the housing of the disadvantaged, the possibility of access to a suitable housing for every Iranian household in accordance with the household's needs in such a way that the housing concern does not exceed other areas of the household's life and stable and safe access to the household's housing is also guaranteed, showing the ideal vision of the housing sector in documentary studies, is related to disadvantaged groups. The purpose of this study is to achieve the set of strategies and the general form of realistic and effective programs in the field of housing support for the deprived and low-income groups, which, while determining the limits and type of government intervention in relation to housing and different economic groups, will make the target groups enjoy support programs faster. This study is based on the combined model of SWOT strategic analysis and QSPM strategic planning model and examines the findings of studies and the results of interviews with experts in the field of geography and urban planning. SWOT analysis showed that 1- Ignoring the lack of simultaneous use of the process of management and operation of low-income housing based on the participation of local social institutions and non-governmental organizations 2- Lack of necessary knowledge or disregard for the diversity of needs of the deprived and disregard for Special Characteristics of Target Groups 3. The imbalance between the benefits of different individuals in different groups in relation to support programs has led to the inefficiency of the policies of the deprived and the enjoyment of supportive housing for this group. "Empowerment programs" and "Attracting participation by exploiting local capacity and internal capacities by developing and diversifying empowerment", along with a general balancing policy to increase capacity in non-governmental sectors based on household participation. Faster households have support programs Provides housing and participation of all stakeholders in planning.

Rapid urbanization causes the number of problems for citizens and urban managers, which noted the need to adopt strategies and approaches to improve the condition. In the meantime, the concept of quality of life was developed to assess the condition in cities. The quality of life as a multidimensional concept in the economic, social, physical, and other dimensions has been discussed and utilized at various levels and scales. In this research, with the aim of measuring the quality of life in informal settlements of Tabriz, survey method has been used for this purpose. It can be said that the mental attitude of quality of life dominates this research, which Satisfaction and mental opinion of the residents are the basis of work. One-sample T-test and path analysis were used to analyze the data. The results indicate that the average of all dimensions of quality of life is lower than the average, and the only socio-cultural factor is higher than the average. Also, the average total quality of life is 2.82, lower than the average, which reflects the poor quality of life in these neighborhoods. Based on path analysis, the economic dimension with 0.685 has the greatest impact on the quality of life in these neighborhoods. It can be said that any planning for these neighborhoods will be done taking into account different dimensions, in order to be effective.

Optimal condition of accessibility and rapid, easy, and safe travel to health_ treatment land uses can be performed by the systematic analysis of transportation sub-systems like behavior. Developed countries are in essential need of proper transportation system for better accessibility. This paper aims to develop model, considering mode chains as well as the individual characters. This study benefits the analytic and quantitative research methods in developing mode choice model to evaluate the movement pattern of travel to health care centers in Shiraz central district (district 1). Each mode is the dependent variable whereas the socioeconomic characters are the independent variables. Filled questionnaire and geographical information system is used in collecting data. To generate the model, multinomial logit model was used that shows public transport like metro and bus are not the popular modes in access to hospitals. Movement pattern cognition in accessibility to special urban land uses, has an efficient role in urban policies and planning, which can be generalized and indigenize to healthcare travel behavior in other geographical areas. Results show that car ownership will increased the private car travel rate 8 times according to beta coefficient.. Taxi is the mode which is used in all three travels. People with lowest range of income and education use bus as their mode. Besides metro travel also has significant relation with low level of income and increase the travel rate 9 times.

One of the theories that studied poverty and inequality after World War II and urban reconstruction in America in the duality of the suburbs and the central city is the theory of Spatial Mismatch. Despite the role of the background caused by racial-ethnic inequality and the contrast between the suburbs and the central city in the formation of the aforementioned theory, the main indicators of Spatial Mismatch indicate the lack of appropriateness between obtaining a job with sufficient benefits to access affordable and quality housing. This means that the backgrounds, structures and processes of inequality are different from one society to another and the lack of proportionality between the benefits of work and access to housing represents the spaces of poverty. The aim of the current research is to reveal the Spatial Mismatch between the two mentioned indicators in the metropolitan areas of Tehran. The current research is applied research in terms of its purpose and descriptive-analytical in terms of its method. The main data required include major occupational groups and housing status in official population and housing censuses, which have been analyzed using spatial functions. The analysis of the research findings shows that there is a direct relationship between occupational stratification and the quality of residence in Tehran's municipal areas. In such a way that the concentration centers of the lower classes and workers who are deprived of jobs with suitable benefits have been formed in residential areas with poor quality and worn-out textures. Based on this, in the southern regions of Tehran, there is a greater disproportion between getting a suitable job and access to quality housing. While in the northern areas of Tehran, there is much more suitable work and access to quality housing. The final result shows that the two main indicators investigated well reveal and represent the «Spatial Traps of Poverty» which are the main focus of Socio-Spatial Issues in Inner City Areas.

Objectives The purpose of this article, the relationship between maximum temperature of Kerman province geopotential height at 500 hPa to avoid risks and losses are extreme temperatures. Method In this paper, the approach has been used in the circulation to peripheral circulation patterns will be assessed based approach to environmental data. Therefore, we used two databases. First Base event database environment (surface). In this regard, the surface temperature is selected stations Kerman province. The maximum temperature of the stations in the period 01.01.1368 to 01.01.1398 for 30 years to 10957 the number of days were obtained from the meteorological province. Another database contains data that the data of geopotential height at 500 hPa

Today, with the expansion of urbanization and the increase in the population of cities, urban poverty is one of the important problems that it seems necessary to fight. In the 21st century, one of the indicators of urban progress is the issue of low urban poverty (Lemanski and Marx, 2015). In order to analyze and evaluate the indicators of urban poverty in Rasht city in different blocks and to cluster social poverty in this city (very poor, poor, average, wealthy, very wealthy), to analyze social poverty and extract spatial hot spots from Arc software. Gis was used. And the extraction of different areas of the city was calculated from the R software and by the multi-indicator Prometheus decision-making method, where the weight of the indicators was obtained by the ANP method from the raw data of the statistical blocks of Rasht city in the census of 2015. The findings of the research showed that comparatively, the central parts of the city are covered by medium blocks, and in the outer and peripheral parts of the city center, two hot spot areas are observed, which contain very prosperous blocks. Cold spots are also clearly visible on the outer edge of the city and they cover very poor and poor blocks, and except for the hot and cold spots, the city is mostly in the form of mild spots and most of the blocks are in poor condition. They are placed in average social poverty. Also, based on the findings of the research, most of the deprived areas in terms of social poverty in Rasht city are located in the north-west and north-east parts of the city.

The purpose of this article is to analyze the frequency and severity of the one to six days of rainfall in Iran. The trend of frequency changes and severity of each course was identified using my-candle test and the slope estimator during the 1968-1988 period. Then, using the main component analysis method and cluster analysis method, the entire stations were categorized in five clusters (abundance) and four (intensity) based on the annual changes of frequency indicators and intensity of precipitation. Cluster 1 and 2 stations represent the frequency of precipitation periods with a severe or without trend. The two clusters were mostly established in the southern half of Iran. Cluster 4 and 5 stations represent the frequency of precipitation periods with a positive (mild) trend, mainly in the northern part of the country. Cluster 3 stations represent the frequency of precipitation periods with decreased (mild) trends, which are mostly focused on west and southwestern Iran. The clustering results of the stations based on the intensity index of precipitation periods, contrary to many results; do not show a specific pattern. But in the cluster, there has been a severe decrease in the last half century. The stations of this cluster are mostly concentrated in the northern parts of the country. Other clusters are scattered in almost all parts of the country. Accordingly, it can be concluded that the frequency of precipitation periods in the northern latitudes of incremental processes (average or weak) and the severity of precipitation periods in these latitudes (north of the country) had severe declining trends.
