Integrated Geophysical, Remote Sensing and GIS Studies for Groundwater Assessment,

The integration between advanced techniques for groundwater exploration is necessary to pro-tect and to manage the vital resources. Enhanced Thematic Mapper Landsat (ETM+) images, a geographic information system (GIS), hydrological modeling and direct current (DC) resistivity geoelectrical techniques were used in integrated manner to identify the groundwater potentiali-ties in the study area. The study area is approximately 1195 km2, located at the western portion of south Sinai. From the results of the eight thematic layers as input to GIS model, the suitable loca-tions for dams could be estimated in the two main drainage basins Matulla and Tayiba
