IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

The unstructured scaldis model: a new 3d high resolution model for hydrodynamics and sediment transport in the tidal scheldt
Author : JORIS VANLEDE(1), SVEN SMOLDERS(1), TATIANA MAXIMOVA(1) & MARIA JOÃO TELES (2)
ABSTRACT
In the framework of the projects "Integral Plan for the Upper Sea Scheldt" and "Agenda for the Future", the SCALDIS
model, a new unstructured high resolution model of the tidal Scheldt is developed in TELEMAC 3D (Telemac-Mascaret
software platform). Starting from the stated model purpose, a weighted dimensionless cost function is set up that attributes
equal weight to the vertical and the horizontal tide. By adapting the bottom roughness, the cost function is minimized
during model calibration. Quantification of the model skill and cost function calculation is done using the VIMM toolbox
which is developed and maintained at Flanders Hydraulics Research. The quantified model skill of the SCALDIS model
shows that the model is well suited to assess the effects of changing the bathymetry and geometry of the Scheldt river on
water levels, velocities, tracer dispersion and residence times, and that the hydrodynamics can be used as the basis for
sediment transport calculations (both cohesive and non-cohesive).
