Abstract

The present study involved the documentation of the most important geomorphological features of certain regions along the sea coastlines of Khoms, Ka'am, and Zliten cities located to the west of the Capital Tripoli. A high-definition digital camera "Nokia" is used to maintain high-quality photos of the whole geomorphological features. Based on the nature of the geological processes that generate the different geomorphological features in the studied regions, two main types were distinguished: the depositional features (as a result of marine deposition processes) and the erosional features (as a result of marine erosional processes). This study also revealed that Khoms coastline is characterized by smooth and even territory with low elevated cliffs that in most cases vanish wherever the beach and shore zones became larger. The picture was completely different in the coastline regions of Ka'am and Zliten (in special), here, the terrain was extremely steepened due to the gradual proximity of the coastline to the highly-elevated cliffs that led to a narrowing of beach and shore zones. Rockfall, demolition, landslide, and creep processing dominated at coastline regions of Ka'am and Zliten in special. These processes took place because of the highly-elevated cliffs with their noticeable steepness towards the coast as well as their brittle and non-consolidated nature coupled with wave storm action, especially during winter seasons. As a result, coastline regions in Zliten and Ka'am become retreated and large rock blocks as well as boulders and detritus took place in front of the cliffs’ feet and were subjected to the continuous wave current action within beach and shore zones. In general, the sea coastline of Khoms is considered a "low-laying coast" covered with sand, small gravels, and several dunes, while the sea coastlines of Ka'am and Zliten were considered to be "coasts of emergence" characterized by rocky beaches.
