Hydrogeochemical and geomorphological studies of some wadis on the eastern side of the gulf of Suez, Sinai, Egypt

Abstract EN

The purpose of this study is to examine the relationship between the geomorphological characteristics and hydrochemical properties in the Baba, Feiran, Sudri, and El-Tayiba basins, located on the eastern side of Gulf of Suez, Sinai.

In each catchment the stream order, bifurcation ratio, frequency, and drainage density for each basin, together with the rainfall analysis and possible runoff are measured or estimated.

Rainfall varies from 20 mm/year in the eastern head water regions to 55 mm/year in the west, near the Red sea coast.

The Feiran basin has the highest weighted average annual precipitation and hence, the value of runoff.

Hydrogeochemical studies include analyses of major cations and anions in groundwater samples from different aquifers and from different hydrographic basins.

Mineral saturation indices and correlation coefficients were computed for all the groundwater samples and interpreted in relation with the geomorphological parameters.
