Sharon plain in Israeli Coastal Plain region

The Sharon Escarpment of Sharon Cliff[1] is the escarpment in Israel that connects the level of the coastal plain with the level of the Mediterranean Sea beach and the continental shelf and stretches along the coastal ridge approximately between Giv'at Olga and Tel Aviv, i.e., along the Sharon plain.[2]

The escarpment is up to 45m in height, of steepness 75-90°. The escarpment gradually moves eastward due to collapsing and slumping seawards. The separated slabs of sandstone slide downwards and crumble completely into fans of sand, swashed away by waves. The catchment area of the escarpment is visibly eroded by runoff, but this erosion is negligible compared to rockslides and slumps.[2]

The escarpment is threatened by road building, sand quarrying, drainage, slope grading, and other uncontrolled tampering with the topography. [2]
