Results of this research which had been done by hydrogeological and geoelectrical survey for fresh water resources in the study region (wells and springs) show that the fundamental aquifer of underground water in AL-SIN region belongs to Jurassic. Th
e alimentary basin of AL-SIN spring depend upon filtration of rain water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation on west and south-west where we find flow place of AL-SIN spring and submarine springs near seashore.
The study area is located in the eastern part of south eastern side of Jabal.
Kassion to the west of Barza Al Balad village. The site was selected to
construct electric power station. The electric prospecting technique was
applied to clarify the f
ollowing:
١-Structures.
٢- subsurface caves
٣- Fractured areas and their trends.
This study includes laboratory measurements using different models in
order to determine the effect of wall-phenomenon on the electrical resistivity
measurements, and field applications. This phenomenon had been studied in
the case of homogeneous
medium of which the resistivity is constant, and in the
case of unhomogeneous medium, composed of two or three different layers. It is
found that the effect of this phenomenon is the same although the medium
resistivity is different or with the increase of the number of layers. This
phenomenon changes according to the measurements conditions such as the
measurements direction concerning the edge of slope or wall, the distance
between AB electrodes, and the distance between the configuration and the
wall.
