Coupling of 3D remote sensing images, Field sketching and field investigation represent interesting techniques to understand and evaluate the slope stability problems along rock cut slopes. These methods were applied along the highway section that connects the Sohag, Red Sea, and Cairo governorates on the eastern plateau, Egypt. It is one of the most used highways in Egypt during recent years and represents the backbone of Egyptian transportation and commercial traffic. This Highway passes through a difficult zone of
rock cut slopes located 20 km north of Sohag city. Serious stability and rockfall and/or slides issues have been recognized along this section. The applied methods are considered to be good and are new techniques in understanding different types of slope stability hazards such as debris flows, rockfalls/sliding and determining the most relevant factors affecting slope stability problems. In addition, the potential instability zones were mapped. These techniques also could help in remediation/mitigation strategies.
