The purpose of this research was watershed management on sediment control in dryland region . To done this research collected inform, maps, reports about rain, sediment and runoff. In second steep done field works and recorded data, collected inform of checkdams dimensions. The measurement rainfall during research. Measurer put in dam stores to measure of sediment. Measuring specific erosion and specific sediment using PSIAC model. The data indicated that the 11 case rain occur more than 10mm in study area which 6 cases has been runoff, 3 cases rain controlled in dams reservoir and 2 cases has been, not runoff. During the research 545525 m3 flood came to dams reservoir which 0.037 of them was soil particles and other material. Data collected indicate that the 19824 m3 sediment control through dams that each hectare has crated 10 m3 sediment in study area during 2 years. |
