Geomorphologic Evolution and Morphometric Analysis of the Upper Basin (Güzelsu) of the Engil River (Van)

The study area is located in the Eastern Anatolian Plateau found Alpine-Himalayan fold mountain belt. Engil River Upper Basin (Güzelsu) within Lake Van Closed Basin, largest soda lake this belt terms of volume and area. This aims to investigate geomorphologic evolution Güzelsu support development with morphometric analysis. With aim, a Digital Elevation Model (DEM) was created aim quantifying evaluating field observations findings, 22 subdrainage areas basin determined by DEM. indices Hypsometric integral, curve, shape, Elongation ratio, Drainage asymmetry, Mountain front sinuosity Valley width-height ratio were applied these drainage which formed depending on internal external processes. When geomorphological sedimentological findings studies evaluated index results, it revealed that geomorphology under influence tectonism, climate fluvial
