Abstract
Reservoir sedimentation is one of the most common lakes and reservoirs degradation. With land use change and more development in the catchment area, soil loss becomes more imminent causing more sediment yield into the reservoir. With this uprising trend, it is important to predict sediment yield using soil loss (RUSLE) and sediment delivery ratio (SDR). This modelling is simplified in GIS. This paper compiles prediction of sediment yield for reservoirs in Malaysia based on soil loss model (RUSLE) calculated in GIS for Cameron Highlands and Chenderoh (Perak). The analysis show that land use change increases sediment yield. Sediment yield rate for reservoirs in Cameron Highlands is higher than the sediment yield rate for Chenderoh.
