Abstract
The present study deals with the geology, hydrology, aquifer characteristics and hydrochemistry of the Quateranry Nile Delta aquifer in the Gharbiya Governorate. This is based mainly on data obtained fiom RIGW and the published information on stratigraphy, structure, sedimentology, geomorphology, climate, hydrology, well lowg techniques and hydrochemistry of this aquifer; and also based on physical and chemical properties determined by the writer for 82 groundwater samples collected from domestic and irrigation wells during 1992, 1993 and 1994 fiom the whole area. Several conclusions have been achieved from the present study that can be summarized in the following paragraphs : - 1- The study area lies within the limit of the Mediterranean climatic zone and has an average precipitation ranges fiom 48 to 59 mm, an average annual temperature of 20 OC, an average annual relative humidity of 74% and the evapotranspiration demand in the area is 4 mm/day. 2- The principal uses of groundwater in the Gharbiya Governorate are mostly for domestic, public and irrigation supplies. The total quantities of water abstracted fiom the study area are 270 million m3/y. 3- Geomorphologically, the present Nile Delta is considered as the ideal model for deltas in the world and its topography varies from 17 m above sea level in the South (near Cairo) and decreases gradually towards the North direction to become zero level at sea shore. The Nile Delta includes the following physiographcal depositional provinces.
