ABSTRACT
Fifty six sediment samples, taken from seven boreholes drilled in
Sharm EI-Sheikh basin, are subjected to laboratory measurements of
grain and bulk densities, porosity, cementation factor, electrical
resistivity, grain size and elastic modulii.
Some physical models and normograms are constmcted to relate
the obtained hydrogeophysical parameters to each other. These
