The present work aims to elucidate for the first time the hydrogeological conditions in the Argeen (west Lake Nasser) and Adindan (east of the Lake Nasser) areas on both sides of Lake Nasser. The Abu Simbil sandstone rocks ocuupy most of the western and eastern shorelines of Lake Nasser. The groundwater is exploited from Abu Simbil sandstone aquifer and exists under unconfined conditions. The depths to basement rocks are recorded at depths west of Lake Nasser(313 m) while they are recorded shallower (212 m) at east. The saturated thickness of Abu Simbil sandstone aquifer ranges between 30m (Adindan area) and 312m (Argeen area). The main result of the present study shows that the seepage water from Lake Nasser attains 15 million m3/year. This huge recharge from the Lake Nasser increases the groundwater head in the Nubia aquifer.
The groundwater potential in the west of the Lake Nasser (Argeen area) is high than in the eastern part (Adindan area). The rise of water table from 1965 to 2015 ranges between 29.61m and 51.86m reflect the impact of Lake Nasser on the groundwater in the study area. The calculated transmissivity for two productive wells attains 409m2/day (Argeen area) and 305m2/day (Adindan area) indicating moderate potential of Abu Simbil sandstone aquifer. The groundwater salinity ranges from 229ppm to 782ppm. The groundwater salinity reveals an increase of groundwater salinity towards the west direction in Argeen area (west of the Lake Nasser) and the east direction in Adindan area (east of the Lake Nasser) confirming the groundwater flow from Lake Nasser to abu simbil sandstone aquifer.
