ABSTRACT
ABSTRACT: Two case studies for the computation of reservoir sedimentation are described in the present paper: Forggensee Reservoir (Bavaria, Germany) and Yermasoyia Reservoir (Cyprus). The physical processes that were quantified, are: runoff resulting from rainfall, soil erosion due to rainfall and runoff, inflow of eroded particles into streams, sediment transport in streams, sediment inflow into the reservoir, and sediment deposition in the reservoir. The above physical processes were included in a mathematical simulation model which computes the inflowing sediment quantity into the reservoir considered from the corresponding basin. The computed sediment inflow into Forggensee Reservoir was compared with available sediment yield (suspended load) measurements at the reservoir inlet for 12 years (1966-1977), while the computed sediment inflow into Yermasoyia Reservoir was compared with the measured mean annual rate of soil erosion in the corresponding basin. In both cases, the comparison results are satisfactory.
