In this research, hierarchical analysis model was used to spaial selection of the area. After analyzing the data, the relative weight of the options, sub-criteria, criteria and the final weight of the options of each layer was calculated in Excel software. The findings of the research showed that the settlement of the areas was inversely related to the height factor, the distance from the permanent river and the slope, among the geomorphological factors. Barracks and Tepe Mahor have the highest coefficient of importance. About 89% of the enclosures are located in suitable places and less than 3.5% of the enclosures are located in inappropriate locations. According to Pearson's correlation, the factors of slope, height, distance from permanent river were identified as the most important factors in the distribution of ancient sites in bottom Seymareh 2 basin.

Changes in space over time are the result of various processes and trends governing it. In this regard, this research tries to evaluate and analyze the spatial changes of Sirjan Basin. For this purpose, the basin method and spatial analysis techniques were used. The results of the research show that the rainfall in the last Quaternary was 17 mm in the central parts of the basin and almost 300 mm in the high altitudes. This amount of change in humidity and ambient temperature has caused a fundamental change in the morphogenic system of the region. Currently, there is no active glacier system in the region. Also, the temperature conditions of this basin have increased from -3.6 to 0.86 degrees Celsius. The maximum temperature of the basin has changed from 16.46 in the cooling phase to 17.64 in the present time. Of course So that the highest temperature difference was related to the highest part of the basin and the lowest difference was related to the lowest point of the basin. Tracing the alluvial terraces of the old lake of Sirjan shows 4 terraces around the lake. As the highest terrace was identified at a height of 1719 meters, according to this, the water volume of Sirjan's old lake during the glacial period was 80400 m³. Manuscript profile -

The main purpose of this research is to identify the influencing factors on land use changes in the villages of Astane Ashrafieh County. In the first part of the research, Landsat satellite images were used to investigate land use changes. In the second part, factors affecting land use changes were analyzed using statistical analysis. Based on this, 28 villages of the County were studied as a case study. The research method was descriptive-analytical.Questionnaire technique was used to collect data and statistical methods were used to analyze data. The results showed that among the independent economic indicators, the benefits of investing in the land and housing sector had the strongest correlation and relationship with land use changes. Among the independent social indicators, the indicators of the role of the owners of the second house in the village and the increase in the number of residential tourists and the need for land for construction had the strongest correlation and connection with land use changes. Among independent physical indicators, tourism in the study area had the highest correlation and relationship with land use changes. Correlation analysis between independent institutional-management indicators and land use changes showed that indicators of the weakness of executive bodies in informing agricultural land owners about the type of land use and the prohibition of land use changes had the highest correlation and a very strong relationship with land use changes in the village.

Monitoring air pollution is an important task in public health. Also, the unavailability of ground station data is often prevented due to the lack of network of ground monitoring stations to know the exact amount of air pollution in different parts of the country. Therefore, the use of remote sensing images in continuous monitoring of air pollutants due to their low cost and low manpower, will be appropriate and cost-effective. In this research, Sentinel 5 satellite images and MODIS sensors have been used for analytical study to detect the average trend of changes and spatial distribution of dust in Khuzestan province. The aim of this study was to use relatively high-resolution satellite data for local monitoring of air quality/air pollution and to investigate the relationship between Sentinel and MODIS image sensors. Findings indicate significant amounts of AOD in several parts of the study area such as Ahvaz, Abadan, Khorramshahr, BandarMahshahr and Bavi. Also, a small amount of fine dust is seen in the southeastern, eastern and northeastern cities of the province. According to the results of this research, as we move from the southeast, east and northeast and move towards the southern and western parts of the province, the amount of fine dust increases.

The performance of De Martonne, Ivanov, precipitation effectiveness, continental coefficient, temperature, rainfall anomaly, percent of normal precipitation, vegetation, aridity and Selyaninov indices were investigated using the data of 15 meteorological stations. The effective climate index determination was done using simple additive weighting (SAW), TOPSIS and simultaneous evaluation of criteria and alternatives (SECA). The sensitivity analysis of the SECA method rather to the β coefficient had a significant effect on the results. Based on the ranking results of three multi-criteria decision-making methods, Ivanov's index performs well in severe climate conditions (with extreme high and low values), and in other climatic conditions, it is better to use it together with another climate index. The percent of normal precipitation index was overestimated in most of the stations. Rainfall anomaly index also described the climatic condition of most stations as close to normal. In determining the effective climate index, the number of meteorological data, the type of their mathematical relationship and the way of climatic demarcation are of special importance. The highest amount of intensity and percentage of changes was in the case of SAW and SECA, TOPSIS and SECA methods. The highest number of first ranks in three multi-criteria decision-making methods is related to De Martonne, aridity, vegetation indices and then effective precipitation index. Manuscript profile -

It is necessary to check the pollutants carefully using precise techniques. In this study, elements of NO2, CO, and Particulate Matter effective in air pollution were analyzed spatially and temporally (monthly, annually) using the TROPOMI instrument of Sentinel 5 sensor in East Azerbaijan province. Investigations showed that in the cold season, more areas of the region experience the presence of CO and NO2 pollutants, which are mainly caused by fossil fuels, industries, and residential areas. But their concentration is high in the hot and cold seasons respectively. Evidence shows that in densely populated areas, we are facing high concentrations and the presence of NO2. A high concentration of suspended particles is also seen in the summer season. According to the findings, all three elements have a high distribution in the cold season; on the other hand, the concentration and spatial distribution of pollutants is influenced by factors such as weather, topographical conditions, and industrial centers.

This device is composed of various elements and components along with their interaction. The result of the action and reaction of these elements and climatic components is the formation of various climatic phenomena. One of the climatic phenomena that has received little attention in Iran and the world is the sultry phenomenon. Therefore, the view and purpose of this study is to analyze and evaluate the effect of climate on human physiological comfort and convenience under the influence of sultry phenomenon. The research is of applied type which has been done by descriptive-analytical method. The data used include average minimum, maximum and daily temperature, relative humidity, precipitation, steam pressure and dew point temperature in the statistical period of 40 years(1979-1979). For data analysis, indices of sampling intensity, partial steam pressure and sampling degree have been used. The study area in this research is the city of Rasht in Gilan province. The results indicate the greater effect of temperature element in establishing thermal comfort and the irreplaceable role of water vapor pressure and dew point temperature in construction physics. Despite the low relative humidity in June, July, August and September, the amount of sultry and the most heat disturbance is seen in these months, and August has the most severe amount of sultry. In order to establish thermal comfort, in addition to creating shade, natural air conditioning is also needed, and in this regard, solutions have been provided. Manuscript profile -

The results show that the minimum average annual temperature in the catchment increases between 1.2 to 3.4 °C and the maximum temperature increases between 1.3 to 3.7 °C in future periods compared to the base period. The amount of evapotranspiration will increase in monthly, seasonal and annual time scales in the future climate, compared to the current conditions, so that the maximum increase in annual evapotranspiration in the distant future period and under the RCP8.5 scenario will be equal to 12.3% compared to the base period. The twenty-year box plot in future periods under different scenarios show that the highest evapotranspiration uncertainty occurs in the period 2061-2080 and under the scenarios RCP8.5 and RCP4.5 respectively. According to zoning maps of evapotranspiration changes in the basin, the highest amount of evapotranspiration changes will occur during the period 2061-2080 and under the RCP8.5 scenario in the western regions of the basin. Considering that Karun River originates from the mountainous areas on the north of the basin, increasing the temperature and in turn, increasing evapotranspiration in future periods will reduce the level of snow coverage in the area and will have significant negative effects on the flow of Karun River and can thus reduce the water resources of the basin.

Earthquakes are followed by many geomorphological hazards and environmental consequences, which cause great damage to vulnerable areas. Following the earthquake of November 13, 2017 Sarpol-e-Zahab-Azgaleh, many slope processes such as (landslides, landslides, subsidence, etc.), as well as natural consequences (changes in the flow of springs), economic, human consequences (destruction) Residential areas, roads, destruction of agricultural lands, orchards and fish farming complexes) occurred in the area, causing damage to areas affected by the earthquake. In this research, using satellite images, field operations, the required information about the occurrence of geomorphological processes and natural and human consequences in the region were collected and their location was identified and determined on a map. In addition, with the help of Arc GIS software, zones Exposed to location threats and some of the consequences of earthquakes, their location and map were plotted. The results of the study showed that the activation of most processes, amplitude instabilities as a result of weak geological structure, monotonic and morphological conditions of the region are affected by the occurrence of earthquakes, which their past history also confirms this.
