The project of Wadi al Bab and Wadi Ahmar in Libya aims to deveplop the available water resources, both surface and groundwater. The study area is approximately 2,000 km², located on the south-western flank of Jebel Akhdar Mountains,30 to 80 km southeast of Benghazi.
The climate of the study area is semi-arid and its mean annual precipitation is 100 to 200 mm high. With First Escarpment as a border, to the west is spread the Benghazi coastal plain, and to the east, a table land. Tertiary rocks and Quaternary deposits are distributed. Each formation of Tertiary period displays transgressive and regressive facies and are comprised mainly of marine carbonates.
In this paper, some results of hydrogeological investigation, such as groundwater storage conditions, water quality, water balance and etc., will be discussed.
