Process erosion is one of the most important degradation process, particularly in semi-arid climate. Identify the sediment of the issues is important for watershed managers and planners. The main purpose of evaluating and comparing the potential contribution of this research has been deposition of marl formations. This study was conducted in hablerood basin and in the northern city of garmsar. for this reason, constructive map lithological was prepared as a unit in geographic information systems.then, the potential value erosion on sediment collected simulators rain comforts' with intensity4mm and continuing 10 minutes in the category marl and none marl has been determined. the results showed that in hablerood basins contribution marl and none marl land respectively59.4 and 40.6 percent. While in terms of lands area. marl and none marl land respectively 21.4 and78.6 percent.particularly sedimentation marl lands was 2.38 ton in hectares, that twice none marl land.this study showed that the use of simulators rain in order to determine the contribution of sediment formations suitable method for watershed planners, to estimate the erosion rate is correct.
