The use of groundwater is one of the ways to overcome the seasonal shortages of water. Underground dam that can be noted as one of the techniques to help the improvement of water resources management and increase the efficiency of these resources, is one of the water storage practices to use the groundwater. . It is a simple method for the collection and storage of water in arid and semi-arid areas. In this study, selection of suitable areas of underground dam in Gharasou watershed is investigated. Many factors are influenced in determining the suitable areas of underground dam. In this research, physiography, geology, hydrology, hydrogeology and land use of the watershed were investigated and analyzed with the use of information, maps, reports, required data and geographic information system. Then, derived maps from different stages were combined and finally suitable areas and streams for construction of underground dam were mapped. Results showed that about 30 percent of Gharasou watershed is suitable for construction of underground dam.
