Smolders, S.; Bi, Q.; Maximova, T.; Vanlede, J. (2018). Modelling cohesive sediments in the Scheldt estuary (Belgium) with SEDI-3D, in: Bacon, J. et al. (Ed.) Proceedings of the XXVth TELEMAC-MASCARET User Conference, 9th to 11th October 2018, Norwich. pp. 53-60
A new cohesive sediment transport model for the Scheldt Estuary is presented in this paper. The model is built in SEDI-3D, which itself is part of the TELEMAC-3D code. The 3D hydrodynamic Scheldt model, Scaldis, was used for hydrodynamics. One fraction of fine sediments is modelled as a tracer. The results show good agreement with point measurements and with estimated transport rates and directions. However the local turbidity maximum is dependent on a local sediment source and a fix for excessive deposition of mud in shallow areas needs a more elegant solution.
