Abstract

The present research attempts to study detail morphometric analysis of Harrir and Shaqlawa watersheds in the northeastern part of Erbil city, north of Iraq. The areas of the watersheds are 350 Km² and 223 Km² for Harrir and Shaqlawa, respectively. To achieve the aims of this study, the ALOS PALSAR Digital Elevation Model data, and Geo-information (Remote sensing and GIS) techniques were used for determining and analyzing morphometric parameters in terms linear, aerial and relief aspects. Several tools in ArcGIS 10.4 software were utilized for preparing and producing maps, analyzing and assessing various characteristics of the parameters. The main results show that there is a strong inverse relationship between stream order, number and length of the stream in the watersheds of the study area by R² values (R² = 0.78 and 0.81 of Harrir watershed and R² = 0.8 and 0.79 for Shaqlawa watershed, respectively). The watersheds are elongated in shape with dendritic, sub dendritic to parallel drainage patterns. Moreover, detail morphometric analysis shows that the watersheds have a low runoff, low permeable material, and moderate slope. The structural geology and climatic parameters of the study area have influenced the landform development and stream behavior in the watersheds. Hence, the present study is useful and essential for watershed management and planning rainfall harvesting.
