Abstract
The study area, South El Tahrir, lies in the Western Nile Delta, Egypt. It is
bounded by latitudes 30° 30´ and 30° 50´ N, and longitudes 30° 20´ and 30° 50´ E
with an area of about 24000 Km2. It is bounded by El Rayah El Nassery from
east, El Nubariya canal from north and to the north of Cairo-Alexandria desert road
The study area is promising area for a new reclaimed projects, it is suffering
from hydrological problems as, water logging and high salinity. The present study
deals with geoelectrical resistivity techniques and analysis both the groundwater
and surface water and introduce solution for these problems in the investigated
area. To achieve this target, a total of 24 Vertical Electrical Sounding stations
(VES’es) were carried out along the investigated area in the area free from
groundwater wells. The geoelectrical succession consists of three geoelectrical
layers (A, B & C) that the second layer divided into two geoelectrical unites (B1 &
B2), which act as water-bearing according to resistivity values.
The surface water system represents the main recharge resources of
groundwater aquifer. It is composed of Rosetta branch, El Rayah El Beheri, El
Nasseri and El Nubariya canal. Other canals are branched from El Nubariya canal
such as El Nasr and El Bustan canals.
Pleistocene aquifer system represents the main groundwater resource for
domestic, industrial and irrigation purposes, it has a wide distribution occupying
the area to the east and north of Cairo- Alexandria desert road and extends toward
northeastern and northwestern to merge with natural extension of the Pleistocene
aquifer under the Nile Delta, it extends towards southeastern to merge with
Moghra aquifer of Miocene at Wadi El Farigh and toward southwestern to merge
with the Pliocene aquifer at Wadi El Natrun depression.
