Theme-II-4-Simulation of spatial groundwater behaviour in south-west Punjab.

Abstract

The assessment of groundwater resource of South-West Punjab has been carried out through estimate of seasonal groundwater recharge and water balance study. The season-wise (khariflrabi) quantification of various components of water balance equation has been done for the period from 1990-91 to 1999-2000. The groundwater behaviour of the selected area has been simulated using the finite difference groundwater flow model 'Visual MODFLOW'. The model was calibrated and validated using observed groundwater heads for the period from 1990-91 to 1999-2000. The groundwater heads obtained using the model compares reasonably well with the corresponding observed groundwater heads. Thus the model 'Visual MODFLOW' can be used successfully to simulate the groundwater behaviour of south-western part of Punjab state and to predict the future spatial groundwater behaviour in the selected tract.
