Abstract
    The aim of the present report is to investigate the transient (=non-steady state) evolution of 
    suspended sediment concentration and mud dredging volume in the Scheldt in relationship to the Deurganckdok in the period after the opening of the dock, the period around 2011 when the upstream discharge was reduced and the maintenance dredging strategy changed, and in the years following the peak.The study is performed using long-term numerical model simulations over the period 2006- 2015. In consultation with the client, it was opted to perform the simulations using the existing LTV-model instruments, consisting of the NEVLA3D model for hydrodynamics and a DELWAQ model for sediment transport, with an offline coupling between the two models (van Kessel et al., 2010).
