Gully erosion and its dangers in the Wadi Suera Basin in Erbil Governorate

Abstract

The research dealt with the study of the risks of groove erosion, which is located in the northeastern part of Iraq, using GIS technology, with the aim of assessing the spatial variation of the risk of water erosion in the Suera basin, as the layers of natural factors affecting the occurrence of groove erosion were collected for the purpose of producing a map of water erosion risks in the basin. The study found that there are six levels of groove erosion in the Soueira basin, ranging from low-erosion areas constituting 3.65% of the total area of the Suera basin, and areas with high groove erosion amounting to (0.8%) of the total basin area of (156 km²) of the research area. The nature of the rocks unfolding in the basin and their topography and morphological characteristics were reflected in determining the effectiveness of groove erosion in the Suera Basin...
