In recent decades, low-yielding rainfed farms have become known as the main sources of sediment production and soil erosion in the country. Therefore, more research is needed on the factors affecting erosion and sediment production in these areas. This research was carried out with the aim of studying the effects of slope and rainfall intensity on erosion between rainbow trout in test farms in Kermanshah provinces using field descendant simulator. In a preliminary study, the erosion situation in the high slope drilands of the province was studied by field observations. Then, in some representative fields (in terms of erosion, slope and climate class), the status of erosion and agronomic management and its components were examined and soil sampling was carried out. 11 farms were selected in the current management conditions and in the dominant slopes (10 to 30%), and rainfall simulator test were performed in these farms and erosion and runoff were measured. The results showed that in sloping fields, the percentage of crop residue and slope, respectively, significantly controls the process of runoff production and soil erosion.
