NUMERICAL MODELLING OF SUSPENDED SEDIMENT TRANSPORT IN THE LOIRE ESTUARY
Numerical modelling of suspended sediment transport in the Loire estuary In order to evaluate silt displacements and deposits in the outer part of the Loire Estuary over one year, a two-dimensional depth-integrated model of suspended sediment transport has been carried out. It takes into account transport and dispersion of suspended sediment by tidal currents, and […]
