الملخص الإنجليزي
Jabal Al Akhadr is a major recharge area for bedrock aquifers underlying the Batinah Plain in the north and the interior desert areas in the south. The Hajar Super Group (HSG), a local classification rocks, mainly composed of hard limestone in which the groundwater moves along fractures, mainly result of tectonic movement. The aquifer of this area mostly is controlled by second porosity i.e., Karts, faults and fractures. This project presents the hydrogeological assessment of the Al Jabal Al Akhdar applying the modern technical tools like remote sensing and Geographic Information System (GIS).
The main purpose of the project was to integrate remote sensing and GIS derived information with other data such as geological structures, geology, the location of wells and springs with their yield to identify several potential drilling sites.
The methodologies used for this project are mainly, data acquisition from satellite images and previous studies; data processing by GIS software and interpretation of the data supported by field work and ground truthing.
The study shows that in the Al Jabal Al Akhdar area, considerable yields could be obtained from wells in the Hajar Super Group limestone, especially at the intercepting fractures. The study also identified that the eastern part of Saiq Plateau has important groundwater development potential. The study area is characterized by many large faults intersecting Hajar Super Group formations. The analyses of the lineaments interpreted from the TM Landsat data along with hydrogeology data indicate that the presence of high dense lineaments could control water accumulation in some areas, where as in other areas no control because there are other factors such as type of cementation within the fault can control the accumulation of water in the fracture zones.
