Hydraulic scale models are still the most powerful tools in studying estuarine problems (density flows and salinity intrusion). Weak points are, however, uncertainties in the scaling laws for vertical mixing of salt and momentum and in the boundary conditions. Experience with the Rotterdamse Waterweg model shows the importance of an automated model operation and control and the availability of adequate boundary conditions from nature. A very good reproduction of tidal propagation, flow field and density distribution was possible. The model has been useful in providing support for management decisions related to the development of the estuary.
