Résumé
Focused on evaluation of groundwater quality and potentialities of different aquifers for sustainable development between Beni Mazar and Mallawi, west El Minia, mainly Nubian sandstone aquifer, Eocene limestone aquifer and Oligocene aquifer. The thesis dealts with the hydrological characteristics through collecting data of 73 wells. In addition to geochemical analysis of 33 water samples. Management of groundwater in west El Minia was discussed by using the mathematical processing (MODFLOW) model to predict the future drawdown in groundwater levels through applying three scenarios. Concerns with the hydrogeological catalogue which reveals that, the groundwater is available from three aquifers : Oligocene aquifer, Nubian sandstone aquifer and Samalut aquifer with significant variations in their hydrogeological conditions. These distinctive conditions reflect pronounced differences in local morphologic, topographic, lithologic and tectonic features that control the groundwater occurrence, depth to water, the water movement and water quality. Groundwater flow value and its direction are calculated. The water table contour map was constructed with flow pattern for the Samalut limestone aquifer using the available records of the wells data during the field trip. Hydraulic parameters of the Eocene main aquifer (Samalut Formation) is also calculated. Focused on management of groundwater in the study area and discussed carefully by using the mathematical Processing MODFLOW model to predict the future drawdown in groundwater levels by applying three scenarios, after 50 years till the year 2068 indicating the high potentiality of Eocene aquifer.
