Abstract:
The wadi Tanezzuft is nowadays an inactive fluvial valley located in the SW Fezzan, an hyperarid region of the Libyan Sahara. In the wet Holocene (11-5 Kyr BP) there was an endorheic river which ended in a large delta system and the area was inhabited by human communities. In order to reconstruct the palaeoenvironment detailed study of the geomorphological features and reconstruction of palaeohydrographical setting can be obtained through the analysis of satellite imagery with middle (ASTER and LANDSAT) and high resolution (IKONOS) and Digital Elevation Model (SRTM). During the geoarcheological field surveys a large amount of data (archaeological finding, 14C and TL dating) has been collected which permits to date the environmental changes.
