Abstract

Agricultural droughts are droughts that affect the crop production or the ecology of a region. Ravar city that is located in margin of desert and the north of Kerman province is one of these areas. Due to the existence of enough underground water that entrance to desert and high evaporation to improving agricultural and cultivar activities, it needed to study the construction of underground dam in Ravar area. Therefore in order to (sake) controlling the subsurface flow that entrance to desert in west of Ravar city that is arid for cultivar agriculture, a site in the margin of desert in space of ten kilometers in the north of Kerman province (Ravar city) has selected and the needed studies has done in several step. At first the physiographic, hydrology, climatology, social economics and engineering geology study has done and the result shows the need of supplementary study. In second the geophysics study has done for Assessment of alluvial thickness and bed rock depths. in the third step the geotechnics activities for Assessment of exact depth of bed rock ,ground water table and sampling for field and laboratory testing in order to ( sake) Assessment of physical and mechanical specifics. In fourth step the pumpage test has done Assessment of hydrodynamics coefficient such as (T and S). At finally the design and executive of subsurface dam with the modern methods has done and the result of monitoring shows than the dam has constructed very successfully with positive effects to ground water flows
