This study is based mainly on the interpretation of LANDSAT-i satellite images for an area covering about 85,000 km2 including the west of the Nile Delta and the adjacent north Western Desert of Egypt. From this study; new geological, structural lineation and drainage maps have been constructed on scales of 1 : 500,000 and 1:1,000,000. Furthermore, the groundwater hydro geological characteristics and potentials of the same area have been compiled and evaluated in the light of the new investigation to help proposed reclamation projects to be carried out there.The investigated area is covered by extensive exposures of sedimentary.
rocks ranging from Late Cretaceous to Holocene, in addition to foreland basic volcanic of Late Oligccene-Early Miocene age. It has been possible to construct on the LANDSAT images thirty four geological.
And environmental units in the investigated area. Of especial importance from the scientific and applied points of view, is the classification
and mapping of the Miocene into nine units; the Pliocene into four units and the Quaternary into sixteen units. This work helps to decipher the geological history of northern Egypt, the Mediterranean.
Sea and the Nile Delta. At the same time these units represent great contrasts in physical and chemical characteristics influencing the suitability of soils for land reclamation^ and the movement and quality of groundwater and drainage water on the surface and in the subsurface.
It is emphasized that additional irrigation waters should not be introduced in the area of investigation until detailed geological and hydro-geological studies have been carried out.
