| The construction of underground dams for storing groundwater resources can be one of the suitable solutions for the supply and development of water resources. If these dams are properly implemented, can be stored water in wet season and used in dry periods. This study was conducted to select appropriate sites for the construction of underground dams in the Keryan-Minab watershed in Hormozgan province in three stages. In the first step, the Boolean algorithm was used to remove inappropriate regions. In the second stage, using field views, suitable sites from potential areas were determined. Subsequently, the SWAT model was used to simulate this flow due to the importance of subsurface flow in locating dams. Which was used to calibrate and validate the flow from observation data of the station. This verification was approved by the 61 coefficient and the Nash-Sutcliff coefficient was 0.62. The final stage was prioritized using multi-criteria decision making models (TOPSIS and VIKOR) and based on the 10 criteria of suitable sites. The results showed that in the tops method, Bondar Dam was ranked first with a score of 0.73779 and in the VIKOR method, Senderek dam with the Q index of 0.94 ranked first priority. |
