15-Modelling of Strem-Aquifer Interaction in a Part of Hindon Basin.-Abstract

Abstract

Many rivers particularly small ones in northern India are flooded during the monsoon period but flood water flows off in a short time and cannot be utilized. However, potential shallow aquifers occur in these areas which are known to be interconnected with these rivers. Lowering of water-table in these areas may result into a substantial recharge of these aquifers due to the influent nature of these rivers(Gupta et al.,]985) It is therefore, necessary to quantify the extent of this recharge under different scenarios. An experiment is reported (Nabi Hasan et al.,1990) to have been carried out in a part of the river Hindon near Gagaiheri,dist. Saharanpur, U.P. The water table in this area has gone down by 5 meters due to successive droughts during 1985-87. It was found that during 1988 when the monsoon was normal water-table has been found to be almost fully recouped.
