Abstract
Through studying and analyzing the processes of wind and rain erosion in Altun Kupri subdistrict, it was clear that the progress of wind over water in the study area, as the volume of rain erosion in the study area according to Douglas index reached (1,187) m3/ km2/ year in Kirkuk station and reached (0.507) m3/km/year at Makhmour station. As for erosion capacity of rain according to Fournier equation it reached (48.48) tons/hectare in Kirkuk station which classified within weak erosion range, while in Makhmour station it reached (58,52) tons/hectare which classified within moderate erosion range, this difference in the capacity is due to the difference in rain and terrain between the two stations. As for the ability of wind to wind erosion according to (Chepil) equation it reached (52,15) for Kirkuk station which classified as medium erosion range, while in Makhmour station it reached (83,29) which classified as high erosion rang, this difference is due to the terrain difference. According to Berjsma classification showed presence of three levels of erosion which ranged between weak, moderate and severe erosion, medium erosion got the biggest percentage of total erosion. The study concluded that climatic factors are the decisive factor in the occurrence of erosion processes.
