Abstract
The present study deals mainly with the hydrogeological aspects of the groundwater resources in the investigated area. Hydrogeological and hydrochemical analysis as well as geophysical survey were conducted to verificate all aims of the present study.
The area under study occupies the reclamation lands and covered by sedimentary rocks ranging in age from Tertiary to Quaternary. from the geological studies and geophysical interpretations, two main aquifers are detected in the area (Pleistocene aquifer and Eocene fracture limestone aquifer). The wells tapping these aquifers are drilled at depth ranges between less than 10m and more than 80m. Regionally, the groundwater of Pleistocene and Eocene aquifers flows toward the north and west directions. The recharge of these aquifers takes place from the direct downward infiltration of the excess irrigation water and the flash floods.
The Hydrochemical characteristics are evaluated based on the chemical analysis of 3 surface water samples as well as 85 groundwater samples, representing the Pleistocene and Eocene fractured limestone aquifers. The TDS values of the groundwater of the Pleistocene aquifer range between very fresh and brackish, while in those of the Eocene aquifer varies between fresh and saline water. There is a general decreases in the water salinity of these aquifers from east to west. The dominant chemical water types are Ca(HCO3)2, Mg(HCO3)2 and NaHCO3, in the groundwater of the Pleistocene aquifer, while, NaCl is dominant in the groundwater of the Eocene aquifer.
The hypothetical salt combinations show that there is hydraulic connection between the Nile water and the groundwater of both aquifers. The hydrochemical classification indicates that water of the Pleistocene aquifer is reflects primary alkalinity characters while the water of Eocene aquifer reflects secondary salinity properties. Surface water and most groundwater of Pleistocene water are suitable for drinking and irrigation, while most of the groundwater of the Eocene aquifer is not suitable for the same purposes.
The Geoelectrical studies reveal that, there are four layers in the studied area. The first layer is loose sand and gravel, clay and sandy clay represent the second layer and characterized by low resistivity. The third geoelectric layer represented the water–bearing formation and composed of saturated sand and gravel. High remarkable resistivity values are characterized the fourth layer which represents the fractured limestone and it considers the second aquifer in the area. Contour map shows that the maximum thickness of Pleistocene aquifer is reached to more than 140 m. Resistivity map of Eocene aquifer show that, it lie directly under the Pleistocene deposits.
