The structured grid approach consists of the combination of the NEVLA 3D model with 4 detailed 2D models (which are nested in the NEVLA model). The unstructured grid approach consists of the 3D SCALDIS model. Model performance is checked by comparing model predicted velocities against 67 different ADCP measurement campaigns.
In general, SCALDIS shows the best performance on velocities throughout the Scheldt. The updated flow fields are therefore extracted from SCALDIS. The velocity data calculated by the SCALDIS model is exported as ASCII files over one tidal cycle during both spring and neap tides.
