Geomorphology of Wadi Lulub Basin, Al Jabal Al Akhdar, Northeastern Libya

Abstract

This paper discussed the geomorphology of the Spiral Basin, in Jabal Al Akhdar, where the study aimed to identify the general features of the surface features, and study the natural characteristics of the study area from the structural structure, geology, climate, water and vegetation cover, where several approaches and methods were relied on, including the descriptive approach in describing geomorphological phenomena, and the method Quantitative analytical in the analysis of climate elements, digital elevation model analysis, and analysis of topographic and geological maps, as well as the analysis of some morphometric characteristics of the basin. Respectively, according to the Fournier classification of rain erosion, the randezina soil is the most common type of soil, constituting 56% of the basin area. A high value indicates that the basin has reached a very advanced stage of its subsurface cycle. The drainage density of the spiral basin is 0.85 km/km².
