Abstract
Shores are persistently affected by breaking wind waves. This effect might result in shoreline reformation towards either the landside or the seaside by removing or transferring beach soils from one place to another. The shoreline reformation towards the landside is known as shore erosion. The erosion takes place in case of shore cliffs composed of weakly cohesive soils having steep slopes where eroding the cliff from the beneath results in unbalancing the repose angle and ultimately being collapsed. From the inspection of available satellite images within the last decade, it was noticed an increasing activity of such phenomenon along the shoreline of Tajura municipality where the circumstances are proper for the erosion to take place. The erosion has reached noticeable levels in some coastal region of Tajura where the coastline became within few meters away from the shoulders of the coastal highway at the most extreme erosion. In this research, an evaluation study was conducted to design shore protection structure for the eroded regions aiming to protecting the shore from such a phenomenon. The study included simulating wave propagation using the most widely used numerical model in this field based on the extreme storms recorded west of Libya. The study incorporated the various physical processes waves undergo and the factors affecting the water level variation including climate change. The results pointed out the effect of shoaling on wave breaking through the limited wave heights. Typical cross sections of the structure were produced using revetments for rocky and sandy seabeds.
