Investigation of effective factors on implementation of underground dams Case study: Meyanrud (Ravar) underground dam in Kerman

The construction of underground dams is one of the effective solutions for the providing of water for different consumptions in minor ratio. These constructions are used for preventing the crisis and scarcity of water in tropical and semi tropical zones. These dams can improve the condition of environment and aquifers. In this research the necessary factors for selecting an appropriate place for making underground dam in Miyanrud River in Ravar city of Kerman province are investigated. For this purpose the desk studies and field investigation are performed. After the elementary studies on site, geoelectric studies are performed for recognizing of depth condition of ground such as thickness and sediment of source of dam. By manual digging and geotechnical investigations the depth surface of water and amount of under surface current water are measured. With the geophysical exploration and geotechnical investigations in axis and reservoir of underground dam, Underpass flow measurement at the section of the river, Groundwater Quality Assessment and also the routing of Salinity of Subsurface flow, the proposed site of underground dams was investigated at the distance between Ravar city to margin of desert. Results showed that the selected site has relatively suitable condition to construct an underground dam.
