In the framework of some recent projects carried out at Flanders Hydraulics Research it was found that the model grid of the NEVLA model could be improved. The objective of this study is to improve the model grid and adapt the bathymetry. First of all the numerical schematization of the Deurganckdok was improved. The model grid was extended to include the entire area of the dock. Also the grid resolution was refined.
In the Sea Scheldt it was noticed that some parts of the intertidal area (the so-called slikke and schorre area) were not included in the model. In order to have a better model, the model grid was extended and necessary adaptations were made to include these areas.
Furthermore, it was noticed that the Durme was only partly included in the numerical model. This tributary of the Sea Scheldt was extended up to the limit of the tidal area.
In the original model the dams of Ballastplaat and Ouden Doel in the Sea Scheldt were schematized as thin dams in U and V direction located next to each other. Some efforts were made in order to schematize both dams in a better way, by adapting the local bathymetry. A new bathymetry was defined based on the available bathymetric samples.
Finally the model with the adapted grid and bathymetry was calibrated and validated. The analysis was based on the comparison of the magnitude and phase of the calculated and measured high and low waters.
