Spatial Modeling of Geomorphological Hazards for ‎Morphodinic Processes ‎in Haditha Region - Western ‎Iraq

Abstract

Objectives: To demonstrate the accuracy of using remote sensing data in determining risk levels, then identify the natural factors of the region and the extent of their influence in determining risk levels and build a model that shows the levels of geomorphological risks using remote sensing data (RS) and geographic information systems (GIS). Method: The inductive and analytical approach leading to the adoption of quantitative methods and approaches in the use of mathematical standards and spatial information systems software in order to build models that simulate reality to provide an analytical vision of work mechanisms. Results: The possibility of relying on modern technologies to determine levels of risk by building a mathematical model for them. It became clear that there are three levels of risk, as the low-risk lands reached an area of ​​(1038.66 km2) and are spread on both sides of the Euphrates River, while the moderately dangerous areas reached an area of ​​(1058 km2). While the area of ​​the most dangerous areas reached (1117.7 km2). Conclusion: Variation in the weak geological formations in the region, which led to a large number of fracture joints and separation surfaces, different directions and numbers of linear structures and surface characteristics, as well as poor vegetation in the region, which led to varying levels of danger in the region.
