Abstract

In the present study groundwater sustainability of Indus river sub basin aquifer were analyzed using the numerical model. The water table is declined from 106-137ft in the years of 2012-2016. The increasing demand of water is causing the cone of depression to decline which may the dissolved contaminants in it or the intrusion of groundwater with surface water. The effect on groundwater regime by the continuous increasing abstraction of groundwater according to existing pattern of groundwater development was analyzed by estimating discharges and recharging of the aquifer. A discharge to a safe yield must be applied to attain the sustainability of the groundwater. For modeling of the groundwater for sustainability management, Micro FEM is used because it can explain all parts of the aquifer in deep study i.e. by drawing contours, flow lines, transient modeling. Wells data along with its coordinates, elevation, heads, discharge capacity and daily working hours is required. The decline in the water table shows the excess of discharge rate than the recharge rate. The flow lines show that the direction are towards the wells of the nearby area and which has more working hours and exactly there the cone of depression is deepened.
