摘要

In the framework of the European Project MAST3-COSINUS, developments have been made inorder to predict cohesive sediment behaviour in estuaries with accuracy. The final aim of the project is toimprove numerical models, in order to predict sediment transport in the case of real estuaries.This report is the contribution of the Laboratoire National d’Hydraulique et Environnement (LNHE) of EDF,regarding the Loire estuary (France). The model gives good results. Comparing the general pattern of theturbidity maximum and the order of magnitude of the computed concentrations with observations, it’s obviousthat sediment prediction is in progress thanks to the developments considered here.This work is co-financed by the European Commission, Directorate XII for Science, Research &Development, through the COSINUS project within the framework of the MAST-3 programme, contractMASC3-CT97-0082.This study has been done within an agreement between EDF-LNHE and the Centre d'Etudes Maritimes Et Fluviales(CETMEF) from the French Ministry of Equipment. It has been financed by the Direction de la Recherche et des Affaires Scientifiques et Techniques (DRAST), through the contract 98-DST-17.
