Abstract:

Five different numerical models are used to reproduce estuarine cohesive sediment transport and intercomparisons are made of the resulting predictions. Comparison with test cases have shown that the numerical treatment of cohesive sediment is very sensitive to model parameters and formulations, and requires good calibration. Some of the specific processes that have been developed through the MAST.3-COSINUS European project are used here to improve the ability of numerical models to reproduce the sediment behaviour in real estuaries. Despite this progress, it is shown that numerical models results still have many limitations, and their results should always be interpreted with great care. © 2002 Elsevier B.V. All rights reserved.
