6 Recommendations
Based on geophysical and TDS results, the following recommendations can be
considered in the area for groundwater management:
1. The most suitable sites for drilling new water wells occupy the northwestern
part of the surveyed area around VESes 34, 35, 38 and 39 which shows high
resistivity, high thickness and low accessible depth.
2. Establishing groundwater management and simulation models based on the
current results of geophysical and borehole logs to adjust the exploitation of
groundwater and developing a more effective scenario to determine the optimal
pumping rate from the shallow aquifer and reducing the degradation in the quality
and quantity of groundwater in the area.
3. Fixing a proper network of irrigation and drainage systems in the southern parts,
which will enable optimum use of water with minimum losses and also to void
increasing the soil and water salinity as a result of over pumping.
