STUDY OF A DEPRESSION STORAGE FOR MULTIPURPOSE WATER USE

Abstract

Until recently) the interaction between depression storage and ground-water is either neglected or evaluated as a residual of the other components of depression water balance. This has lead to serious misunderstanding about the role of depression storage in a hydrologic system. Emphasis has been given by the hydrologic community in recent past to conduct systematic research to comprehend this interaction as a physical entity. The mathematical modelling has been found to be potential tool to study the multifacetand complex interaction between ground and surface water. Ia the eastern fringe of lower Ghaggar basin, there exist nineteen interconnected sand dune depressions in Surathgarh area of rigsngcnagar district of Rajasthan which are used as flood cushion from 1968. The depressions have plan.. areas to the tune of 100 Sq .km. at full storage level. Due to the impoundment of water in the depressions r waterlogging in isolated patches in the surrounding area had been first noticed in 1975.
