Geomorphological Risk Modeling of Qashan Valley Basin in Sulaymaniyah Governorate

Abstract

The research aims to model the risks to which Wadi Qashan is exposed by building a spatial database for the region and representing it in the form of thematic maps that can help in making appropriate decisions. The study concluded that the region has three levels of risk: low-risk areas, with an area of ​​(11.9) km² and a percentage of (20.9%); medium-risk areas, which occupy an area of ​​(365.8 km²) and a percentage of (68.4%) of the basin area, and are spread in most parts of the region and are almost suitable for human, agricultural and pastoral activities. The third and final level, which is high-risk areas, has an area of ​​(57.4 km²) and a percentage of (10.7%) of the basin area, and is not suitable for establishing human settlements or practicing agricultural activities due to its risks represented by its high elevations, steep slopes, and rocky nature devoid of vegetation cover, as well as its soil being prone to erosion.
