| Abstract: | A single layer mathematical model was developed to simulate the hydrogeological condition and groundwater flow in an area of about 2536 Sq km, which forms part of the WYC Command area. The model was run both for the steady state and for the transient state. The model was then successfully calibrated. The calibration results were recorded qualitatively and quantitatively. The results of the calibrated model were analyzed. Two Scenarios developed alonwith six scenarios created earlier, in another modeling study, were analyzed to find out a sustainable solution for optimal utilization of surface and ground water. The two Scenarios developed show that a viable solution will be reduction in pumping and regulated surface water supply. This will ameliorate water logging in the nearby areas. The reduction in pumping and thereby, reduction of return flow recharging groundwater can be achieved by improving water use efficiency and modifying/changing cropping pattern. These strategies can be successfully implemented, through mass awareness programmes, involving the farmers, who have to implement the programme, along with all the other stake holders. Ultimately reduction of groundwater pumping can be achieved through strict groundwater regulation. Direct recharge by way of seepage through canal can be reduced by lining the unlined canals and proper repair and maintenance of the already lined canals. But this has to be tested through a pilot project vis-a-vis economic viability of this lining, as seepage may be indirectly helping groundwater recharge in areas without water logging. Further to increase the availability of surface water and augment recharge of groundwater, the surface run off from the precipitation, can be utilized in various ways to reduce to decline of groundwater level. |
