Publicatie type | rapport Deltares
This report presents the setup of the Haringvliet-Biesbosch SWAN model, called swan-hvbbhr2023_ 6-v1a. The model is to be used for performing BOI ('Assessment and Design Instrumentation') production computations. The curvilinear computational grid is taken from the previous model version (Deltares, 2016). We updated bathymetry and obstacles. The directional resolution is 5°. The model uses SWAN version 41.31A.1 and uses the generic settings as recommended in Deltares (2021a en 2021b). The model uses uniform wind- and water level fields. Currents are not included. Sixteen test computations were performed for the combinations of high and low wind speed (47 m/s and 10 m/s), high and low water level (NAP+7 m and NAP-1 m) and four directions (67.5°N, 202.5° N, 270°N, 315°N). The computations did not reveal anything notable. Our advice is to maintain a maximum of 80 iterations for the production runs. However, during the execution of the production runs it is advised to check whether the convergence in the area of interest and at the output locations is okay. There are no measurements available to validate the model. The results look logical and show no abnormalities. Apart from the output locations, the model is suitable for use for BOI production computations.
