Geomorphological hazards of Valley Takbarah Basin in Sulaymaniyah Governorate (Morphometric study)

Abstract

     The research aims to study the morphometric of the Vally Takbarah Basin in Sulaymaniyah Governorate, which is located within the high   folds region of Iraq, using geographic information systems and (GIS) to identify the morphometric characteristics of the basin represented by the spatial, morphological and histological characteristics and the characteristics of the water drainage network.                                              

     the basin is one of the secondary branches of the Basin the Shay River (Daquq) is one of the main tributaries of the Azim River.                                                                              Its area is (206.67) km2, its highest height (1692) m above sea level at the southwest of the basin, and its lowest area (672) m above sea level in the center of the basin at the main stream and estuary. The morphometric characteristics are determined by the nature of the natural factors affecting it. Such as the geological and structural structure, climate, surface, soil and natural vegetation, as several geological formations were exposed in the study area from the third and fourth time.                                                    

      Pebbles and rocks of a basal texture, and the natural vegetation appears in the study area, represented by two types: the natural pasture area and the steppe weed area. As for the analysis of the results of the morphometric characteristics, it was shown that the basin is in the aging stage of a circular shape, and the number of riverbeds in it reached (6) ranks and has rugged terrain and slopes It is dense and its drainage tissue is very soft, which means that it has a high drainage density and has little permeability.
