Modelling Belgian Coastal zone and Scheldt mouth area. Sub report 14: Scaldis-Coast model

With the increasing awareness of sea level rise, the Flemish Authorities initiated the Complex Project Kustvisie(CPKV) in order to start together with all involved stakeholders to define the overall long-term coastal defence strategy for the Belgian Coast. In order to analyze the impact of sea level rise on the morphology of the coast and to assess proposed mitigation measures on their efficiency the need for a flexible coastal model for the Belgian coast and Scheldt mouth area was revealed.

With the increasing awareness of sea level rise, the Flemish Authorities initiated the Complex Project Kustvisie(CPKV) in order to start together with all involved stakeholders to define the overall long-term coastal defence strategy for the Belgian Coast. In order to analyze the impact of sea level rise on the morphology of the coast and to assess proposed mitigation measures on their efficiency the need for a flexible coastal model for the Belgian coast and Scheldt mouth area was revealed. Therefore, in 2015 it was decided to build an integral coastal model within the TELEMAC-MASCARET model suite. The present report describes the setup and validation of the sediment transport and morphodynamic part of the model. Scaldis-Coast consists of a morphodynamic module, a 2D TELEMAC hydrodynamic module and a TOMAWAC wave propagation module. The Scaldis-Coast model is a highly efficient and flexible model that is applicable for short and long term morphodynamics both in the tidally driven off-shore and wave driven near-shore part of the Belgian coastal zone and Scheldt mouth area.
