Geomorphic Indices Analysis of the Rawandoz River Basin, Erbil, Kurdistan Region, Iraq

Abstract

The Rawanduz river basin locates in Erbil, Kurdistan Region, northestern part of Iraq. This study focus to deduce the tectonic activity of Rawanduz river basin by means of using geomorphic indices.The management information programs in generating a geomorphic indices based on Aster DEM 12.5 m resolution data to analyze the drainage scenario of study region from ArcGis platform software (GIS 10.8). Tectonic activity indicated from diffrendent geomorphic variable indices by using the Iat categorize which has four main classes, and the main tectonic action of the region was indicated appropriately which is 2.33, indicating that the basin's tectonic activity is in moderate to active stage and it is representing that the basin is situated tectonically inside the High Folded Zone, Imbricated Zone, and Zagros Suture Zone, or has been impacted by the same tectonic forces in the past geological period, including the final orogenic forces that are still active.
