Abstract

Erosion is a dangerous phenomenon that threatens the land of th world and is considerd as a serious problem. On the other hand the hazardous effects of soil concentration erosion continuously increase. This, along with scalation of the population made people exploit agricultural lands for challenging with starvation. As a results of this action, soil erosion will further causing additional starvation. Sheet and RILL EROSION are two types of erosion in Qomrood watershed that have been often observed in pastures. In this study, after superposing the maps of soil, geology, slope, landuse and climate, more than 150 homogenous units were identified and the following factors for them was determined: i. e. the senility of rocks for erosion, average slope, percentage of bare soil and vegetation cover and CN variables. The severity of each and the TOTAL EROSION were measured by using S.L. M method. The relationships between severity of sheet and RILL EROSION forms to the given factors were evaluated using correlation matrix and stepwise regression multiple method. The results show that the soil and rock sensivity for erosion are the main factors affecting sheet and RILL EROSION in cold semiarid and cold temperate climates. Meanwhile, the accuracy of the resulting models were verified with independent data from the study area. The result of this study can be used to predict the severity of erosion in different forms even for the areas with similar climates, but facing lack of data.
