Update SCALDIS 2019: a 3D hydrodynamic model of the Scheldt Estuary: calibration report
Vanlede, J.; Chu, K.; Smolders, S.; Decrop, B.; Mostaert, F. (2020). Update SCALDIS 2019: a 3D hydrodynamic model of the Scheldt Estuary: calibration report. Version 3.0. FHR reports, PA016_1. Flanders Hydraulics Research/IMDC: Antwerp. IX, 99 + 45 p. app. pp.
The SCALDIS model is a reference model for the entire estuary of the Scheldt developed in TELEMAC 3D. The model was initially developed and calibrated for scenario analysis of measures in the Upper Sea Scheldt. Based on the hydrodynamic model, both a mud and a sand transport model were developed. Vanlede et al. (2018) proposed an update cycle of 6 years for a re-calibration of the SCALDIS model. This is inspired by the availability of a new spatially covering bathymetry every 6 years. Since the original SCALDIS model was calibrated for 2013, the new calibration is carried out for 2019. This report describes the model development, calibration and validation of the hydrodynamics for the year 2019. The model is calibrated for two spring-neap tidal cycles in 2019 against field data of water levels, velocities (ADCP sailed and stationary in deep and shallow zones) and salinity. Two more stormy periods are selected for calibration and validation respectively. The re-calibrated SCALDIS 2019 model in general captures the hydrodynamics of the Scheldt estuary. The model is considered as a useful tool to analyze the effects of different scenarios of sediment transport and morphology for future studies.
