In the framework of the projects 'Integrated plan for the Upper Sea Scheldt' and 'Agenda for the Future', it was necessary to develop a hydrodynamics and sediment transport model that covers the entire tidally influenced zone of the Scheldt Estuary and the mouth area, and that has sufficient resolution in the upstream part.
Existing models lack a high resolution in the Upper Sea Scheldt, Durme, Rupel and Nete. For this reason, the SCALDIS model, a new unstructured high resolution model of the Scheldt Estuary is developed in TELEMAC 3D for the entire estuary, but with special attention to the upstream parts. The use of an unstructured grid allows to combine a large model extent with a high resolution upstream. The calibrated model will be used to analyse the effects of several scenarios (different morphology of the Scheldt with different ranges of boundary conditions).
This report describes the model development, calibration and validation of the hydrodynamics. The model is calibrated for one spring-neap tidal cycle in 2013 against field data: water levels, velocities (in deep and shallow zones) and discharges.
