Abstract
The research aims to model and analyze water erosion in the Bai Dashk Valley Basin in Erbil Governorate based on the Jarvolovic EPM model, which is one of the modern models in calculating and estimating quantitative water erosion in any region, as its calculation depends on several variables, especially (temperature, rainfall and slope, the state of the vegetation cover and the geological formations of the surface of the region). Accordingly, the research concluded that there is a variation in the amount of quantitative water erosion, as the lowest amount of water erosion was recorded within the category (500-51) with an area of (11.59) km2, and it was spread spatially in a very small part of the study area. Due to its limited spread, it was classified as minor erosion, while the highest amount of erosion ranges in the amount of lost soil between 1500-501 with an area of (159.27) km2. It was spread in scattered and wide parts of the study area, but it was generally concentrated in the eastern and southern parts of the study area. Due to its wide and widespread distribution, it has been classified as medium erosion
