The effect of wind energy on the movement and accumulation of sand accumulated on the beach east of Wadi Kaam in the city of Zliten.

Abstract

The area east of Wadi Kaam in the city of Zliten is one of the most important sites of moving marine sand, caused by the winds in western Libya, as large quantities of sand are produced from different areas on the beach and deposited in the form of moving sand dunes and accumulated at multiple points on the coast in this region that There are major human activities such as coastal roads, agricultural activities, and factories, and therefore these moving sands are always the cause of many problems, and in this study, climate data was analyzed to reach the calculation of the wind energy affecting the movement of sand and its prevailing trends during the seasons of the year and from wind energy and characteristics Volumetric sand samples in the region were calculated sand drift rates and the amount of sand accumulated annually in the region, and from the results obtained it was found that the sand transmission rate in the region is 218.36 tons / km per year, and using the rate of sand density in the sand dunes, the ton was converted to 3 meters and thus became The amount of sand transported in the study area is 565.56 m3/km per year, and this amount, although it does not seem very large, constitutes a major obstacle to development projects in the region, especially with the lack of continuous disposal, as it can accumulate to form dunes that reach a height of more than 10 meters. meters.
