| Summary: | Sustainable supply of water resources in desert areas requires the development of new methods of water supply, which one of the most important methods is using underground dams due to its outstanding characteristics and has a special place in the development of water resources in the world. The indicators of determining the appropriate axis for the construction of underground dam was done in this study, firstly, that the factors affecting the identification of suitable areas for the construction of underground dam were investigated. At the beginning, basic maps including geology, land use and slope were prepared and combined in ArcGIS software through Boolean logic. Then Boolean logic was used to remove inappropriate points. According to the studies and the results of the digging of the keshit diversion dam and also the field studies, the depth of alluvial in different parts of the keshit River varies between 2 and 7 meters in impact point with high dike wall that allows the transfer of subcortical flow to the ground surface easily. Therefore, there is not much limitation in the undergraduate study phase in terms of the depth of alluvial for the construction of underground dam, although due to the shallow depth of alluvial, the possibility of subsurface water storage will not be considerable. |
