الملخص EN

The research aims to identify the characteristics of water erosion of Si Dara basin in Sulaymaniyah governorate, as the research problem is focused on the amount of soil lost due to water erosion, and the possibility of building a mathematical model to calculate the amount of soil lost due to water erosion for the basin whose area is (65 km2), located in the south of Sulaymaniyah Governorate, depending on Based on the (Gavrilovic) model, in terms of the type of rock structure, rate and degree of slope, vegetation cover density, rain and temperature, which depended on the data of the satellite (Land sat oil L8) for the year (2020), and four levels of soil erosion were determined lost inside the basin, ranging between (85-15049.3 m 3 / km 2 / year), and severe erosion constituted the highest levels of erosion by (63.2%) of the total area of the basin (65 km 2)
