ABSTRACT: An
electrical resistivity and electromagnetic emission survey was carried out
involving the use of vertical electrical soundings (VES) and natural pulse
electromagnetic field of the earth (NPEMFE). The use of this new methodology
managed to detect the fracture flow system rupture zones in the underground,
also answered the questions about the deferent subsurface water bodies. The present
study focuses on Marsaba-Feshcha sub-basin in the northeast of the Dead Sea.
Due to the scarcity of boreholes in the study area, several geophysical methods
were implanted. The combination of these two methods (VES and NPEMFE) with the
field observations and East-West transversal faults with the coordination (624437/242888)
was determined, cutting
through the anticlines with their mainly impervious cores with
fracture length of >400 m. These transversal faults saddle inside Nabi Musa syncline (Boqea
syncline), leading to a
hydraulic connection between the Lower and the Upper Aquifer. Due to the identified transversal
fault, the water of the Upper and Lower Aquifer mixed and emerged as springs at
Ein Feshcha group.
