Abstract

Different methods have been innovated for the estimation of sediment yield in different basins. In this research, three methods (hydrometric, hydraulic and experimental) have been used for this purpose in Firouzabad River basin. In the HYDROMETRIC METHOD, in addition to measuring the discharge of the river, sampling of the suspended materials is performed. No hydrometric station exists at Haiqer dam-site, but there is one in Tangab dam-site, some 60 km toward the upstream, and monthly and yearly measuring of discharge and sampling have been performed there in a period of 30 years. To determine the relationship between the river discharge and the sediment concentration, the sediment discharge is measured as a function of flow discharge using coordinated equations. With regard to existing statistical information, the average of annually suspended materials in Tangab hydrometric station has been determined and, by taking some factors and parameters into consideration, has been calculated for Haiqer dam-site exit. To control flood and fix up the river, we need to know the geometry, hydraulics and flow condition of each point of the river. To simulate a river, we usually use mathematical models. In this research, among the current models, the HEC-RAS software has been used, which is one of the most common river models and can simulate sediment transition unidimensionally. Different equations have been presented for sediment total load transition, whose operations have been analyzed and their validities have been determined. Using these equations and sediment transportation methods, the total load has been calculated in HEC-RAS software. The experimental MPSIAC method has also been used for the estimation of sediment yield in the basin. In this method, the effect of nine factors in soil erosion and sediment production (surface geology, type of soil, climate, running water, topography, vegetation cover, land use methods, erosion and channel erosion) is estimated in the basin. Depending on the intensity and weakness of each factor, a mark (of distinction) is given to it and with taking into account the sum of marks, the rate of sediment yield is estimated.
