ESTIMATION OF GROUND WATER RECHARGE DUE TO RAINFALL BY MODELLING OF SOIL MOISTURE MOVEMENT
The purpose of this study is to estimate the ground water recharge due to rainfall by studying one-dimensional vertical flow of water in the unsaturated zone. A model has been formulated for finite difference solution of the non-linear Richards equation applicable to transient, one-dimensional water flow through the unsaturated porous medium. Implicit scheme with implicit linearization (prediction-correction) has been used for discretization. The ground water has been estimated using appropriate initial and boundary conditions for storm and interstrom periods.
