Abstract

The Red Sea coast represents a vital sector of the Egyptian territory due to its economic and touristic activities. Different types of geohazard problems related to the karst features and slope instability were encountered in different areas along the Red Sea Coast.  Karst features are very common in evaporite rocks due to their high susceptibility of dissolution as well as rock falls are distributed along the mountains and rock cuts that located in the vicinity of the roads and highways. The current study is aiming at identifying and mapping all the evaporite rock units and the slope instability sites along the Red Sea Coast stretch between Safaga and Gabal El Zeit, using medium and high resolution satellite images coupled with field investigations. Principal component analysis (PCA) and minimum noise fraction (MNF) were succeeded to map and isolate the evaporite units in the study area. 3D satellites images were used to investigate and extract the most hazardous slope instability sites. Our remote sensing findings were verified by field investigations.
