Description :
The differences in mineralogical composition of the sediments enable the detection and mapping of wadi deposits in the Wadi Sabra valley by remote sensing using different spectral combinations of ASTER and SPOT-5 satellite images. Additionally, laboratory measurements of reflectance spectra were applied on selected surface samples and soil sections from the study area in order to verify the information derived from remote sensing and to quantify the degree of surface weathering and pedogenic processes. The results show that an initial transformation from hematite to goethite is the dominant process related to the recent arid conditions in the study area. Furthermore, it is possible to predict potential new archaeological finding areas using remote sensing techniques.
