The study area is located in the northwestern part of Iraq, represented by the Tharthar Valley basin between latitudes (21 23 34) and (22 26 36) north and arc length (3 42 41) and (42 21 43) east, as the area of the area is (22622 km2) ), that the advantage of using the (EPM) model is that it is one of the most appropriate models in diagnosing the levels of erosion of large areas, through an overlap between the various environmental factors of the region, and this model was designed by (Gavrilovic) in the fifties of the last century and did not gain the attention of researchers until after The revolution that took place in the development of geographic information systems programs, and depends in its application on the coefficient of temperature, rain, vegetation cover (NDVI) and soil properties, and depends on integrating all these parameters into the program (ARC GIS 10.4) by adopting specific mathematical formulas to obtain erosion levels in the region The importance of studying the Tharthar Valley basin is that it extends in vast areas of the Iraqi country in an area that is the main source of surface water, whose investment reflects an important wealth in Iraq’s economy. For erosion, the region is located in five levels, of which it begins with unclear erosion and ends with strong erosion, with the exception of the sixth level, which represents the catastrophic level and the capacity of erosion uprooted as a whole in the region at (13,000) m 3 / year and varies from one place to another, and the study has proven the effectiveness of using modern technologies in calculating levels of erosion. This model. | ||
