The morphodynamic risks of the area between the ‎AlManei Valley basin ‎and the Jibab Valley basin in the ‎north of the western Anbar plateau

Abstract

Objectives: this study aims to identify the risks of material movement or what is known as morphodynamic risks and the explanation of their types, forms and ways to confront them in the area between the Mani Valley Basin and the Jabab Valley Basin north of the western Anbar Plateau according to the geographical vision. It also aims to shed light on the characteristics of the study area and its strategic depth represented by the fact that it represents the middle of the western part of Iraq and the northwestern part of Anbar Governorate.Methodology: The current study adopted the analytical-deductive approach to study the existing reality of the impact of morphodynamic risks in the area between the Mani Valley Basin and the Jabab Valley Basin north of the western Anbar Plateau, in addition to the field study for the year 2022.Results: Following the analysis of the data, the results showed that the impact of morphodynamic risks on land uses in the region represented by (agricultural use, urban use, and transportation). The results also showed that the highest area occupied by agricultural use amounted to (172) km2 and the lowest area occupied by urban use amounted to (14) km2, while transportation routes occupied an area extension of (337) km, as it was found that these uses exist to a large extent in the parts adjacent to the Euphrates River and their distance from the high and sloping parts and from the barren desert lands, which represent dangerous places that residents avoid and avoid establishing any activity in them.Conclusion: A model for morphodynamic risks was created through the layers entered in the GIS programs, and these layers are (rock material movement, morphometric, hydrological, water erosion), as it was found that the study area include (5) categories of risk degrees, which are (non-risk areas amounting to 89 –low-risk areas amounting to 203 - medium-risk areas amounting to 295 - hazardous areas amounting to 248 - high-risk areas amounting to 110) km2 of the study area
