Spatial Modeling of Geomorphological Hazards and their Implications for Transportation Routes Mount Merka Sur in Erbil Governorate as a Model

Abstract

The study's goal is to investigate the influence of geomorphological threats such as rockfall, landslides, and torrential flow on transportation routes in Erbil Governorate's Mirka Sur mountain. The research had multiple axes, the most important of which was an evaluation of the region's most significant natural attributes associated with the incidence of risks. The second axis was used to demonstrate how maps were matched and evaluated using the (Maps Overly) function in the (Arc Maps) application to create a model for geomorphological threats in the region. Which connects two or more layers, and a map was produced that revealed five levels of probable geomorphological concerns based on risk levels.

The study included several axes, the forefront of which was a review of the most prominent natural characteristics related to the occurrence of risks in the region, while the second axis was followed to explain the mechanism of building a model for geomorphological risks in the region, as maps were matched and analyzed according to the (Maps Overly) feature in the (Arc Maps) program. Which works to connect two or more layers, and a map was extracted that identified five levels of potential geomorphological risks according to the degrees of risk.
