The assessment of water resources in Wadi Watir Basin, Sinai by remote sensing and environmental isotopes

摘要

The integrated use of GIS processed remote sensing mosaics and environmental isotopes aided by piezometric informations are found to delineate the most secure places for socio-economic development and in identifying the major aquifers in the Wadi Watir Basin. It is believed that information derived from remote sensing data should help the local authorities to classify the main body of this basin into vulnerable tracts amenable to flash floods and into non-eroding belts liable for cultivation. The environmental isotopes of ~(18)O, and ~2H enabled the identification of three major aquifers, the Quaternary alluvial, Nubian sandstone and a reworked basement ones.
