Abstract

Sediment yield is eroded soil that transported from a place to a measurement point, for example in a reservoir. Sediment in the reservoir is a problem that can reduce the performance of the reservoir, so it needs to be assess regularly. One of many ways to assess is to calculate the potential of sediment that enters the reservoir. The research objective is to calculate the potential of sediment that enters the reservoir at Situ Gintung Dam using two methods, the Universal Soil Loss Equation (USLE) and Schaffernak methods. The USLE method calculate sediment that comes from land erosion of a watershed, but the potential land erosion that occurred is not necessarily create actual sediment load at the river bed so it needs to be correlated with the results of the actual sediment load. The actual sediment load can be calculated using Schaffernak method. The results of that obtain from each method will analysed to confirm the representativeness of the potential land erosion in Situ Gintung Dam. Percent of potential land erosion that transform into the sediment in the water body can be calculated by the value of Schaffernack method.
