Groundwater augmentation by flood mitigation in chennai region a modelling based study

Abstract

The rivers of southeastern peninsular are considered as a newlinehydrological riddle Though these rivers remain dry for most of the years yet newlinethe dry riverbed caters to the demands of the social and economical needs of newlinewater The Hydrologists presumes that rivers are subjected to erratic rainfall newlineand flash floods However the rivers have very good rainfall and offer scope newlinefor recharge of their good groundwater resources The feasibility of newlinecontrolling the overland flow to provide augmentation of its groundwater newlineresources have proves successful These facts have motivated this research newlinestudy by combining surface and subsurface flow system as a drainage basin newlineAs till date much of the analysis were carried out on the surface system alone newlinewhich was described as a catchment to concentrate only on surface flow newlineestimation newline newline
