This method is based evaluating a set of hydrological, geological and topographical parameters that influence the natural occurrence of groundwater. As a result, a ground water potential map (GPM) was generated by modeling these parameters. Groundwater potential map results were classified into three classes that describe the potentiality of each cell in the study area for groundwater exploration. These classes are;high, moderate and low groundwater potential area. It was found that about 7% of the study was classified as high potential areas which were found to be concentrated in the western part of the study area. About 79% of the study was classified as moderate potential for groundwater exploration. The rest of the study area (14%) was classified as low potential areas and concentrated in northeast and southeast part of the study area. These results were verified against existing well data and field observations. Furthermore, a sensitivity analysis was performed to study the effect of each parameter on the overall groundwater map using the effective weight and variation index. It was found that the slope parameter was the most effective among the five used parameters in the model.展开更多

Aeromagnetic data were analyzed using advanced processing techniques (Spectral analysis, deconvolution). The aeromagnetic interpretation was carried out using the analytical signal, horizontal gradient, vertical gradient, Euler deconvolution. The results were improved by the study of enhanced Landsat ETM+ images and correlated with the extracted surface lineaments. Two main lineament sets are observed in the study area. The major lineaments strike NW-SE, NE-SW and the minor E-W. General coincidence of both landsat and aeromagnetic lineaments trends were observed in the study area, which reflecting the real continuous fractures in the depth. The 3D Euler solution of the study area shows that the depth of the magnetic source body ranges from hundreds of meters to more than 3000 m in the middle northern part of the study area. The combined interpretation of aeromagnetic data and Landsat ETM+, added several significant structural elements, that were previously unrecognized from the separate interpretations of aeromagnetic and remotely sensed data.展开更多
