This Note describes a series of experiments with a model of the Eastern Scheldt, located in the southwestern region of the Netherlands. The results demonstrate that the model is well adjusted for the section Oostkapelle-Razernijpolder but that it has insufficient spatial resolution in the northeastern branch of the estuary. The computations need to be performed with a small timestep to achieve good agreement, as amplifications and lags of the semi-diurnal tide and its overtides are influenced differently by the timestep of the simulation. When larger timesteps are used, the shape of the computed wave is affected. Water levels and residual circulations are weakly influenced by modifications to the major system parameters.
