Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Incorporated models or components: Spatial dimensions 1D Spatial extent Model domain Coastal One-line model description Coupled salt Marsh - tidal Flat Transect model Extended model description One dimensional model for the coupled long-term evolution of salt marshes and tidal flats. The model framework includes tidal currents, wind waves, sediment erosion and deposition, as well as the effect of vegetation on sediment dynamics. The model is used to explore the evolution of the marsh boundary under different scenarios of sediment supply and sea level rise. Time resolution 30 min, simulation length about 100 years.

Input format ASCII Other input format Describe output parameters Bottom configuration at each time step. Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? Yes If above answer is yes Other visualization software gnuplot (facultative) Describe processes represented by the model Wind waves are computed by wave action propagation, tidal current are computed with a quasi static approximation. Bottom shaer stress, computed from a combination ot the two, induces bottom erosion. Suspended sediment are advected / diffused by tidal current, and eventually sedimented back. A different erosional process are used where waves break on a vertical obstacle (the vertical scarp at the marsh boundary). Vegetation is computed as a function of the ground elevation respect to the mean tidal level. Vegetation change bottom erodability and the sediment trapping. Describe key physical parameters and equations In each cell and at each time step the following are computed: bottom elevation, above-ground vegetation, water level, wave height, tidal current velocity, bottom shear stress, and suspended sediment concentration. Describe length scale and resolution constraints Transect length about 500 m Describe time scale and resolution constraints Time resolution 30 min, simualtion length about 100 years.
