Abstract
The aim of the present study is evaluating the groundwater resources for the new land reclamation in the area located to the northhwest of Assuit district. In order to achieve this aim the geophysical and hydrogeological techniques were applied. The area under study covered by- sedimentary rocks ranging in age from Tertiary to Quaternary .
Fourty two vertical electrical soundings (VES) were conducted and the interpretation of the obtained data were correlated with the subsurface geologic information brigig from the drilled wells.
from the geophysical and hydrogeological studies, two water-bearing units are recognized in the area , The first is the Pleistocene sand intercalations and the second is the Eocene fracture limestone waterrbearing formations.
Four geoelectric unit~ were recorded in the study area. The first unit composed from loose sand and gravel, clay and sandy clay represents the second unit and characterized by low resistivity. The third geoelectric unit represent the water-bearing formation and composed of saturated sand and gravels. High remarkable resistivity values were recognized in the fourth layer which reflects the fractured Eocene limestone aquifer in the area. The maximum recorded thickness of the Pleistocene aquifer is 110m. The Eocene aquifer lies directly under the Pleistocene deposits with undefmed thickness.
The hydrological characteristics of both discussed including aquifer facies, groundwater occurrence and groundwater regime as well as the aquifer parameters. Regionally, the groundwater of Pleistocene and Eocene aquifers flows toward the north and west directions. The structural pattern groundwater occurrence in the study area. There is a hydraulic connection between both aquifer through this structural pattern. The partial 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 three surface water samples and fifty-five groundwater ones, ,representing the Pleistocene and Eocene fractured limestone aquifers. The chemical properties groundwater of the investigated aquifers were determined and discussed including TDS, major ions, ion dominance, hypothetical salts, hydrochemical coefficient and classification as well as the evaluation of groundwater for different purposes. There is a general decrease in the water salinity of these aquifers from west to east.
The dominant chemical water types are Ca(HC03)2 Mg(HC03)2 and NaHC03 in the ground water of the Pleistocene aquifer, while, NaCI is dominant in the ground water 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, about 63 % of the groundwater samples are characterized by non-carbonate
