Statement

The MARS3D hydrodynamic model is coupled with the sedimentary module MUSTANG to simulate sediment transport dynamics. Based on this model, a configuration has been developed using an orthogonal curvilinear mesh grid covering the Gironde Estuary with its tributaries and the adjacent continental shelf. The vertical grid is discretized in 10 equidistant sigma layers. The model is forced by realistic forcing of the year 2015 (wind, waves, tide, surges, river liquid and solid discharges). The sediment transport module computes the spatial and temporal variations of sand and mud mixtures under the effect of hydrodynamic forcing. In the water column, it solves the advection-diffusion equation for 5 classes of particles chosen to be representative of the natural characteristics of sediment particles in the domain. The sediment initial distribution was uniform and a spin-up year prior to the analysis period was computed in order to ensure the model relevance and to let the simulated waves and currents redistribute the sediment over the domain. Both simulated year parameterization and results are available here.
