On the effectiveness of the vlf-em method For ground water prospecting in the Basement terrains, Sinai, Egypt
MetadataShow full item record
The VLF-EM method is proved to be an effective, fast and inexpensive tool for ground water prospecting in the basement terrains of Southern Sinai. The resistive shallow alluvial deposits increase the penetration depth of the received VLF waves to as deep as 40 meters which is very reasonable to detect the water bearing alluvium in the studied areas. The measured horizontal and vertical components of the resultant VLF-EM field were used to calculate the apparent resistivities of the conductive alluvial deposits. D.C. resistivity soundings were, therafter, carried out at some selected sites to confirm the VLF-EM anomalies and to decide the best Sites for drilling water wells.
