This study describes the set up and validation of the first two models in this ‘model train’: DCSMv5 and ZUNOv3 for the simulated year 2014. The model run 2014 is set up in order to generate the boundary conditions for the morphodynamic models of the Scheldt mouth currently under development by Deltares in collaboration with Flanders Hydraulics Research within the framework of the Agenda for the Future project.
