The present research investigates the possibility of using renewable energies such as solar, wind, geothermal, and bioenergy in the Sistan and Baluchestan province. This province faces significant obstacles in energy supply due to climatic, economic, and geographical factors. Using geographic information and global data in the ArcGIS software, an assessment of the total capacity of the province has been conducted, and areas with the highest potential for renewable energy exploitation have been identified. The assessment results show that the annual energy production capacity from solar, wind, geothermal, and bioenergy sources is equivalent to 1962 kWyear.m-2, 22776 MWyear per turbine, 402 kWyear.m-2, and 194 KWyear per person, respectively, which, if these sources were replaced, would prevent 818.74 kg.m-2, 9504.42 ton (per turbine), 167.75 kg.m-2, and 80.95 kg (per person) of carbon dioxide emissions annually. Furthermore, the annual energy production level in a sample household demand in the study area has been evaluated using GEO T-SOL and PVSYST software. The results indicate that the energy produced by designing a hybrid geothermal and solar system for household demand in the region is equivalent to 8637 kWh and 8858 kWh per year, leading to energy savings of 22566 kWh and prevention of 5585 kg of carbon dioxide emissions annually. The results of this study demonstrate the significant efficiency and potential of renewable energies in meeting the energy needs in the Sistan and Baluchestan province, serving as a valuable solution to address the challenges of energy demand and sustainable development in the region.

The Forozan area of Bandar Abbas is one of the growing areas. Due to the increase in the population in this part, the amount of electricity consumed in the Forozan region has also increased. Considering the style of the structures in this area, the suitable skyline, and the gentle slope towards the south, the buildings have a good potential for installing solar panels, and the possibility of using their produced energy is an effective method of compensating part of the energy. It is required by the region. After the field monitoring of the area, calculating the digital height of the area relative to the base, using ArcGIS software, the topology of the area, the slope, and the skyline have been calculated and interpolated. Modeling has been done for these areas using PVSol software version 2021 with how to install panels in south-direction and east-west directions. By using these panels on the roofs of the buildings in this area, which were technically possible to install, they will produce about 9800-kilowatt hours of energy annually, and after 5 years, the capital of this project will be returned. In the case of covering all the buildings that can be installed in the Forozan area of Bandar Abbas, more than 7.9 MWh of energy will be produced annually and the production of more than 450 tons of CO2 gas will be prevented. The installation of the panel will provide 20% of the electricity consumed in the area.

 One of the subjects of geotechnical engineering is soil bearing capacity, which is a function of the engineering properties of subsurface deposits and foundation characteristics. In this study, the results of 78 exploratory boreholes drilled in Mahshahr Special Economic Zone and Bandar-e-Imam were used to produce engineering geological maps with the aim of determining the soil bearing capacity in that area. The result from the boreholes shows that the sediment of the area is mainly clay and to a lesser extent silty clay and silty sand. After determining the soil classification, engineering parameters were determined based on laboratory test results. Then by using Hansen's formula and considering the allowable settlement of the foundation, bearing capacity was calculated for square foundation (1×1) and (2×2) meters, strip foundation with buried unit depth and a mat foundation (10×20) meters with buried depth one and two meters. By using the ArcGIS software, the load capacity map of the study area was produced and result shows that the allowable bearing capacity in this area varies between 0.40 to 0.98 (kg /cm2) and the northern area has higher load capacity than other area.

The main need of sufferes in natural disasters, is to provide housing, especially to determine the place of temporary residence in critical situations. After the incident, it is not possible to provide suitable places for the injured immediately. Before such crises occur, proper planning must be done to determine the temporary residence so that the necessary infrastructure can be provided and in case of an accident in a crisis situation, it is possible to quickly set up camps for the injured. In this study, to determine the optimal location of temporary residence in Tabriz, various standards effect have been considered such as medical centers, fire brigade, faults, fuel stations, infrastructure facilities, worn-out tissue, watercourse complications. The desired standards were completed at first by experts and once again by experts in this field based on form of a questionnaire, then using the fuzzy hierarchical analysis method, the final weights of each standard were determined. Experts attributed the closeness to the worn-out texture and the second group of experts to the standard of avoiding faults the highest weight. That was important the avoiding standards to hazardous site and the river, for the both experts group. Finally, the last weights obtained the opinions of experts groups from fuzzy hierarchical analysis have been entered in Arc GIS software and the relevant maps that have been prepared using weight overlap in this research. The results show that before the incident, the western part of the city has suitable for temporary accommodation, and after the incident, the central part of the city is appropriate for settlement site. In addition, by comparing the vulnerability maps of Tabriz, the necessary locations for the construction of a temporary housing site were prioritized.

Natural disasters have always existed as natural phenomena during the life of the planet. The occurrence of natural disasters such as earthquakes, floods, storms, etc. has often left destructive impacts on human settlements and has caused heavy casualties on its inhabitants and has imposed heavy economic and social burdens on human societies and countries of the world. . In view of the increasing population, especially in the Third World and developing countries, on the other hand, population density and settlement in old-fashioned and old-fashioned urban contexts and the emergence of problems caused by these issues, cities and cities in particular Babylon has been exposed to adverse effects and management abnormalities. Because the vacant areas have quickly become residential uses, the magnitude of the earthquake hazards has increased as a result. Therefore, the need to reduce the city's vulnerability to earthquakes has become one of the main goals of physical planning and urban planning. In this research, data and information were collected in both documents and field and analyzed in the ArcGIS software environment and after analyzing the risk and vulnerability of the region, it was examined whether the city of Babylon after the emergence of a The earthquake can have the least financial and fatal losses, and there are facilities and facilities available in the city that respond to the conditions of the crisis. Finally, some areas of Babylon were identified as having a high risk of earthquake, and solutions were presented for crisis management in these areas.

Aim of this study is to estimate the optimized volume of reservoir in un-gaged basins and extract the estimation pattern of reservoir capacity for other regions. For this purpose, Ziarat was divided to 9 sub-basins using ArcGIS and the physiographical parameters was determined for each of them. for modelling of volume variation, demand before and after rain and also product before and after spill, were considered as different of Possible scenarios. Time history for amount of volume, was obtained as an equation according to other variables. The optimized volume calculated by mentioned equation as objective function and constrains.i.e. cost, demand and spill for each sub-basin. These volumes vary from 700 to 5000Mm3 and significant relation between volume and curve number index was observed. To extract a relation for prediction of reservoir optimized volume in un-gaged regions, regional parameters and optimized volume was considered and 6 equations was prepared by dimensional analysis and different functions. in this equations, 12 rainfall of 24-h probable maximum event were used for 4 consecutive years (2012-2015). Finally, using R-square and standard deviation error, the more optimized equation was presented.

Determining the proper locations for groundwater extraction in a region by using field observations, geo electric, geophysics and other similar methods, requires considerable time and cost. Determining the appropriate range and locations using existing data can play an important role in managerial decision making and decreasing the negative environmental impacts of groundwater resources extraction. In the current research, required data from organizations, field studies, and Geographic Information System (GIS) were prepared. Then, the potential of groundwater resources was obtained using the ArcGIS software, DEMATEL and Analytical Network Process (ANP) as a powerful Multi-Criteria Decision Making (MCDM) methods. ANP and DEMATEL methods have been used to determine the weight of different themes and their categorization classes to identify the potential groundwater abstraction area. Consequently, the study area was divided into seven sub basins in terms of potential of groundwater resources and change in groundwater consumption, using GIS software. Results showed that 1.94% of the basin has very weak potential, 21.5% weak potential, 39% average potential, 22% good potential, 11% very good, 4.54% excellent and 0.11% of it has a very high potential for groundwater extraction. Moreover, results indicated that land use change to agriculture and urban areas, which reduces the level of groundwater resources recharge, and high agricultural exploitation from groundwater sources were identified as the main causes of groundwater resources threatening in the studied basin.
