Abstract
The present thesis in mainly concerned with the shallow geophysical investigation using the seismic refraction and geoelectric resistivity techniques on Delta of Egypt. An area of about 700 sq. km. in El - Dakahlia is chosen for this study made for the first time in the delta region. In addition mechanical and wet analyses of the Late Quaternary sediments were carried out on samples raised from El - Wastani borehole for the direct correlation with the geophysical results obtained. A sufficient number of map. cross sections and diagrams have been constructed to illustrate results of the geophysical surveys made by the writer. Published informations on sedimentology, hydrology, hydrochemistry and hydrogeology of the delta and coastal areas wer taken into consideration in the interpretation of geophysical results.
