Abstract
The beach of Libda city extends for about 7 km. The shoreline orientation is mainly N70W-S70E. The relation between the direction and duration of the dominant wind, and the orientation of the shoreline governs the net sand transport budgets, toward sea or toward land. The northwestern beach of Libda city is sandy and bordered by sand dunes. On the other hand, the beach becomes rocky toward east and is nearly devoid of sand dunes. The sandy beach is sampled and the mean grain size was obtained for sand transport calculations. The transport budgets along the beach were calculated according to Kadib (1963) formula. The highest transport rate is recorded during spring. Large amounts of sand have been and continue to be removed from the beach by wind landward and accumulate as sand heaps and sand dunes bordering the sandy beach of Libda City. Severe sand encroachment occurs along the western coast of Libda city. Recommendations for the protection of the ancient Libda city constructions are given.
