This research was conducted in two watersheds Dasht-e-Room in Boyerahmad county and Kareh in Dena county using IntErO model. After collecting basic information; the 26 input variables were extracted and calculated using topographic, pedologic, and geologic and land use maps and climatic data i. The results showed that the maximum outflow from the watersheds of Kareh and Dashtrom in 100 year return period are 235 and 179 cubic meters per second, respectively, In other words, the amount of runoff produced in the Kareh watershed is approximately 1.3 times the oufflow from the Dasht-e- room basin and the amount of soil erosion in Dasht-e-Room and Kare watersheds, 105162.22 and 71402.58 cubic meters per year, respectively. Considering sediment delivery ratio of 0.195 in Dasht-e-Room watershed and 0.487 in the Kareh watershed, the amount of soil eroded transferred to the outlet of the watersheds (sediment yield) is 20521.32 and 34800.46 cubic meters per year respectively. The erosion intensity coefficient in Dasht-e-Room watershed is 0.338 and as a result, based on the degree of erosion intensity of IntErO model, the erosion process intensity in this watershed is low and the dominant erosion of the region is deep. The erosion intensity coefficient in Kareh watershed is 0.403 and as a result, the erosion process intensity in this watershed is moderate and the dominant erosion of the region is superficial. The amount of sediment yield per unit area in Dasht-e-Room watershed is 133.53 and in the Kareh watershed it is 347 cubic meters per year.
