Geophysical and hydrogeological tools for groundwater exploration and evaluation in the area around Idfu-marsa alam road Eastern Desert, Egypt

الملخص EN

Idfu-Marsa Alam Road traversing the southern part of the Egyptian Eastern Desert, between the latitudes 24° 00' and 25° 05' N and longitudes 33° 00' and 35° 00' E.

The areas surrounding the road is almost of desert condition and dry climate.

The groundwater in the area is of great importance where it is the unique source for drinking and grazing water.

The groundwater exploration and evaluation in the mentioned area are the main objective of the present study.

Some localities were carefully selected for applying the geophysical and the hydrogeological techniques to achive the gaol of the study.

Both the direct current resistivity and the shallow seismic refraction methods were applied.

Twenty four vertical electrical sounding stations were measured and six seismic refraction spreads were done.

The collected climatic data and the hydrogeological information were analyzed and evaluated using the available software.

Three main groundwater aquifers were detected and distinguished in the area.

The groundwaters in these aquifers are generally present under unconfined conditions.

The water compositions are mainly related to their bearing rocks.

In few localities the groundwater can be used for domestic and irrigation purposes.

The study cleared also that Wadi Abbad and Wadi El Shaghab are the best localities suggested for drilling groundwater wells.

The application of these results is very important for developing the area.
