The collapse of dam structure leads to serious disasters for surrounding areas along the waterway. The objective of this research is to determine a new route for the waterway by using remote sensing techniques. Drainage patterns were determined from Digital Elevation Model (DEM) of Shuttle Topographic Radar Mission (STRM) by using the ARC-GIS software. The most appropriate route for the new valley is determined by using DEM and assisted by topographic maps of scale 1:500000 starting from Toshka lake until Qattara downrange and passing through the depressions of El Kharga oasis, El-Dakhla, El-Farafra and El-Baharia Oases. The route selection is matched with the expected new valley that proposed by Prof. Dr. Farouk El-Baz in his project " The Development Project / Corridor of Development
Project [ 1 ].
