Authors
Abstract
Underground dam is one of the choices of ground water management. These dams are reservoir water in small scale. Because of the low complexity of the construction and low cost and lack of surface evaporation in this type of dam, it is possible to construct these dams in all regions of the country. Various factors involved in site selection of underground dams, so locating them is a complex and time taking. Therefore, in this study, geographic information system (GIS) was used as a new method for locating Channel Rivers suitable for the construction of the dams in Khoshkrood basin in the north of Saveh city. Initially to select suitable areas, a number of criteria such as the dip of the faults and unfavorable geological formations, the unsuitable areas were excluded from the study area. Then among suitable areas with using criteria such as the distance from the Qantas, roads, agricultural area, quality and quantity of groundwater and the depth of the reservoir, three places are selected for dam construction.
