摘要：In this study the numerical model SSIIM 2 is used to simulate
the flow situation and the suspended sediment transport within the
Schwarzenbach reservoir in Germany. Hydrodynamic simulations are
carried out to assess the influence of wind forces and different
discretization schemes on the calculated flow field. A hydraulic plausibility
check is performed based on stationary ADCP measurements to assess the
performance of the model. Both the consideration of the wind and the
plausibility check using an ADCP are hardly used in large reservoirs so far.
The simulation results show a complex flow field with two large (re-
)circulation zones in the middle of the reservoir, whereby the temporal
development of the simulated and measured velocities have comparable
characteristics. Moreover, morphodynamic simulations are performed to
compute the suspended sediment transport. The results show that the
settling behavior of the sediments is mainly influenced by the inflow
discharge and the operation level of the reservoir.

Moreover, morphodynamic simulations are performed to compute the suspended sediment transport.
