title = "Numerical analysis of bed development during pressure flushing with partial drawdown",
abstract = "Within this study the two three-dimensional numerical models SSIIM 1 and SSIIM 2 are used to simulate a physical experiment of a reservoir flushing with partial drawdown of the water level. During the setup of the numerical model, it can be seen that the sluice gate cannot be implemented in accordance with the given conditions in the laboratory experiment. Therefore, different simplifications are performed in the model to simulate the development of the flushing cone. An additional sensitivity analysis is carried out to determine critical modelling parameters. The simulated shape of the flushing cone, obtained by SSIIM 2, is in good agreement with the laboratory results, even if the modelling results indicate a slight underestimation of the eroded volume. SSIIM 1 predicts the amount of flushed out volume in a better way, but the geometric bed changes are replicated less accurately. Therefore, SSIIM 2 is considered to be more suitable for the modelling of reservoir flushing with partial drawdown, even if some simplifications have to be made in the numerical model.",
