One of the methods used for calculating flood peak discharge in non-statistical watersheds is experimental methods. One of the empirical methods used in this study is the Fuller method which has advantages over other empirical methods for different flood periods. In this research, we have compared the linear programming optimization techniques and genetic algorithm in optimizing the fuller experimental formula coefficients in Excel and MATLAB respectively for selected watersheds of the region. For this purpose, the statistics of maximum 24-hour discharge of 9 stations in West Azarbaijan province with a statistical period of 21 years were studied. Comparison of the results showed the superiority of the genetic algorithm method and then linear programming. The results also show that the use of smart search methods improves the performance of conventional methods significantly.

in this research, the effects of the second homes of tourism in Ghaleh Haj Abdullah village have been investigated. The method of this descriptive-analytical and library research is based on field survey in forms of questionnaire, observation and interview. Statistical population of all residents The village of Ghaleh was Haj Abdullah, which was 950 in the census in 1395. For estimation of the sample size, the Cochran formula has been used, according to this formula, the number of samples is 381 people. Also, simple random sampling method was used in the village level. Data were analyzed by SPSS software using T-test. The results showed that the effects of second homes in social, economic and physical-environmental dimensions have been positive, negative and controversial. In the social dimension, its positive effects include increasing social security and reducing the immigration of inhabitants The village has been. As well as negative effects such as increasing urban lifestyle, eliminating the customs of rural customs, social disruption has been among the villagers. Also, in the economic aspect, it has had far more effects than social and physical dimensions. Residents have stated that by creating and expanding second homes, the situation of employment and income of the village has improved, and with the increase of economic activity in the region and the strengthening of the rural economy, the employment of the residents has been provided and the intensity of the rural population has decreased. The latter, in terms of environmental and environmental aspects, have the effects of second homes as an extension of the residential tissue of the village and the growth of the second species of mussels in the fields and gardens of the region, which have implications for land use change and rural landscape change from an agricultural domain to an artifact With villa units.

The insurance industry has a very special place in the economy, and insurance companies are important institutions in the capital market. Insurance activities are considered as one of the important pillars for economic and social development and have a significant impact on the development of the economic and social relations of the country. In the economy of Iran, the growth of the insurance industry is one of the main concerns of economic policy makers. In the current situation, including useful solutions in this regard, the creation and expansion of insurance activities through increased investment in the production of premiums generated by the relative advantages of the insurance company in different regions. The shift model = share is one of the most important and effective models for regional planning analysis. The present research seeks to address one of the important aspects for the establishment and improvement of the performance of private insurance companies by recognizing the advantages of each of the branches. In this research, the existing data was processed using SPSS software and eventually The spatial coefficient of the field of insurance activities of different branches was calculated and finally the application of the model was tested for identification of competitive and structural advantages.

The explosion of the population and the development of cities in the last century have caused many problems, including the destruction of agricultural lands and green spaces, which is the subject of our discussion in this study. The city of Kerman has seen rapid growth in recent years in the city's physical development, with its direct reflection of the loss of green spaces in and around the city. With the help of Landsat images and comparison of land use maps, it is clear that this trend has been rising rapidly between 2000 and 2018. In this research, data gathering was done through field observations and use of Landsat satellite imagery. ENVI, ArcGIS and Google Earth softwares have been used for statistical and visual analyzes. On satellite images in the ENVI software, radiometric correction was performed using Radiometric Calibration, and then by FLAASH Atmospheric Correction, an atmospheric correction was performed to minimize the error. The results show that over the years, almost 11% have been reduced from the share of agricultural lands and wastelands and by contrast, the share of land that has been built has increased the same amount. Therefore, it is possible to make suggestions including the use of infill development for the conservation of agricultural lands, the completion of the green belt of Kerman city by the municipality, construction on the arid lands in the 2nd district of Kerman, preventing land speculation, and fully comply with the rules of comprehensive and detailed plans, especially on urban green spaces.

Several factors affect the temperature gradient of the Land surface, one of the factors affecting human activities is land use changes that can lead to global temperature changes. Land surface temperature changes affect the natural climate of the region, so understanding its changes and balancing it is essential to understand the indirect effects of human intervention on ecosystems and their management. The aim of this study is to investigate land use, land surface temperature characteristics in each land use as well as correlation between land surface temperature variations and normalized difference index (NDVI). In this study, land use, land temperature and NDVI analysis was used from Landsat 5TM in 1990, 2010, ETM7 2000, and 8OLI for 2017. Land use was studied using supervised classification method. The results showed that the amount of land surface temperature in each land use was different and the maximom amount was found in the bare soil and in the built areas and the lowest in the garden. The difference in land surface temperature between built areas with vegetation in the years 1990, 2000, 2010, and 2017 was 3.58, 2.27, 3.20 and 2.12 ° C, respectively. Also, the difference in temperature between bare soil with vegetation cover in these four periods was 3/3, 0.8, 0.81 and 2.38 ° C respectively. In this study, the relationship between NDVI and surface temperature showed a negative correlation, so that areas with low NDVI had higher temperatures than those with high NDVI. The relationship between vegetation changes and surface temperature changes showed a significant correlation between these two parameters (R = 0.63). Therefore, it can be stated that land uses with more vegetation have lower temperatures than land uses with less cover.

The construction of power lines is one of the most important concerns of the electricity industry in the country. The cost of building these lines on the one hand and the interaction of environmental factors on these lines on the other hand has led to different parameters in the routing of these lines. All of these parameters are directly related to the location of the transmission towers and equipment. GIS has various capabilities, including the ability to retrieve, retrieve, update, display, process and analyze reference location information, thus providing a suitable platform in which to define different conditions and parameters as information layers. And, based on the patterns defined by different experts, it was combined and achieved the desired results. The design and implementation of a suitable route in accordance with the natural and environmental conditions and the evaluation and comparison of the designed route with the existing and operating route (Muhammad Abad Line) is the main objective of this research. In this research, in order to find the optimal path between two points of interest, the fuzzy inference model is first obtained using suitable points for rig installation and cost map. The AHP method was also used to weight the factors. Then using the Cost Path function the optimal path between two points is obtained. Also, in order to integrate the information, the weighting method to fuzzy inference rules was evaluated. Finally, the fuzzy gamma model was selected as the best model in the latter method and it was used for routing between Yazd I Post and T-OFF site of Mohammad Abad.
