Title: Relationship between tectonic activity, fluvial system and river morphology in the Dohuk catchment, Iraqi Kurdistan
Abstract:The study area lies along the Dohuk River, which runs from Dohuk Lake to Mosul Lake in Iraqi Kurdistan in the high folded zone of the Zagros Mountain Range in northern Iraq. The geomorphic characters ...The study area lies along the Dohuk River, which runs from Dohuk Lake to Mosul Lake in Iraqi Kurdistan in the high folded zone of the Zagros Mountain Range in northern Iraq. The geomorphic characters of the area such as elevation, basin slope, maximum flow distance and average overall flow were derived from the Digital Elevation Model. The indices used include the Stream Length-Gradient Index (SL), which is higher in the upper section than the lower section of the study area. The variability of land surfaces is in the lower section of the study area and it can be seen that this is not only due to the uplift of the Zainiyat foothills but also the activity of the drainage pattern flowing into the trunk stream of the Dohuk River. Drainage basin asymmetry (Af) indicates that uplift in the study area is occurring in the west and tilting in the east. The Transverse Topographic Symmetry Factor (T) is shown to indicate that the river basin is almost symmetrical and this has an impact on the drainage basin in the study area. Mountain Front Sinuosity has relatively high values. Field investigation in the study area has shown that there are three layers of deposits in the upper section of the area and five layers in the lower. An increasing quantity of deposit is linked to the volume of flow in the main channel in the lower section of the valley, the soft lithology of the rock and uplift of the slopes of the Zainiyat foothills.Read More
