ABSTRACT
Many developing countries are located in areas where the rainfall is seasonal and unpredictable. In these countries, water is supplied through storing in wet years for dry years. One way to overcome seasonal shortages of water is utilization of groundwater. However, in the late dry seasons, in some areas, even underground water resources are also depleted. Alongside, in some other areas, underground water is not available so that there is a need to dig deep wells and install pumps to exploit water which is not cost-effective. Unfortunately, the groundwater levels have declined in recent years due to inefficient management. This matter causes lot of issues including drop in groundwater levels and salinity of soil and water. The expertise believe that the construction of underground dams can be partly overcome these problems. The issue whether the construction of underground dams is in consistent with the objectives of sustainable development or not and in what extent needs to be cautious. The present study attempts to identify advantages and disadvantages of different types of underground dams to determine the future sustainability of such structures from economic, social and environmental viewpoints.
