Investigation of the Water Basins of Kalafgan District with GIS Analysis

The rapid and unpredictable growth of the population, the development of cultivation, and the lack of surface and underground water management have caused problems in the irrigation and hydrological system in Kalafgan city. In this region, the lack of sufficient water diversion dams and the canalization system, at the same time as the rapid development of cultivation and agriculture, have caused problems for the residents of this city. To solve the water shortage, there is a need to increase the number of water diversion dams, manage surface water, and determine and identify water sources and drainage patterns. Determining and stabilizing the location construction of suitable dams and channels in the regional study is determined by using a geographic information system. One of the effective sciences in the field of earth and environmental science studies is the use of geographic information systems, which is very useful in the accurate estimation of hydrometric parameters of watersheds. In this research, as an example of hydrometric studies of the water basins of Kalafgan city in the geographic information system, the digital elevation model (DEM) has been used with the help of geographic information system software for the studied basin.
