Abstract

In order to provide pilots guiding ships near the harbour of Rotterdam in the Netherlands with accurate current information a considerable effort has gone into the modelling of the region around the 'Hook of Holland'. The currents in this region to a large extent are influenced by the flow of fresh water from the Meuse and Rhine rivers and by the wind. This necessitates the on-line forecasting of the currents, since the number of pos- sible combinations of wind and river outflow is simply too large to tabulate. Moreover, the clear three-dimensional structure of the currents makes the use of a three-dimensional model necessary. In the present study a three dimensional model of the area was com- pared with a large set of measurements for various settings of the mo
