  Water scarcity in arid areas is a serious crisis. The most important step in using rainwater collection systems is to locate suitable areas. In this research, three methods of multivariate regression model and GIS have been used to locate the on-site and off-site rainwater collection method in Tejreh watershed. In this study, canopy, litter, rock and gravel, bare soil, CN, precipitation, slope and soil depth as independent variables and influence on in situ rainwater collection and maximum instantaneous discharge for non-in situ rainwater collection method The title of the dependent variable was considered. The multivariate regression model uses stepwise method, backward removal method, and forward method. And the standard step-by-step method, regression removal method, step-by-step method in collecting rainwater, non-in situ method have been used. The final results by matching the results of previous research show in step rainwater collection, stepwise method and between layers CN, soil, percentage of rock and gravel, and in non-in situ rainwater collection stepwise regression method Standard and among layers the percentage of litter, percentage of canopy, CN, slope, percentage of rocks and pebbles, amount of rainfall, percentage of bare soil and soil depth are known to be important in the equation. Finally, the importance of rain collection sites was divided into four classes: very good, good, medium and poor. Manuscript profile

  Wastes pollution is the source of many environmental problems. These pollutants cause water, soil and air resources pollution and destruction of natural landscapes and spread of disease, while waste disposal centers pose a threat to rural areas, despite the appropriate distance from urban centers. Determining areas suitable for landfills is one of the general strategies to deal with this crisis. In this research, which has been done by descriptive-analytical method and relying on library resources, after collecting raw layers related to 12 indicators (rural, urban, roads, water resources, floods, land use, pastures, soil, geology, faults, communication roads, etc.) and preparing distance maps and its scaling were investigated using linear software in GIS software of suitable areas for waste disposal in Qasr Shirin city due to its special location in terms of abundant water resources (mineral water and ecotourism). The results show that most of the city of Qasr Shirin is not suitable for waste disposal, these areas are shown in red in the final output of the models. Also, only the parts of the city are suitable for this purpose, which are marked in blue in the final output of the models. Manuscript profile
