Development of Groundwater Flow Model Using Visual MODFLOW

A steady state finite difference model, MODFLOW, is developed to quantify groundwater in Choutuppal Mandal, Nalgonda (Dt) AP., using GW data from 19 observation wells. Well inventory and base map are used to assess surface features, GWL and direction. MODFLOW is conceptualized as two layered weathered and fractured aquifer system spread over 19215 m x 10366 m area. Result shows that the computed groundwater level contours are in good agreement with observed ones.
