Also known as
Model type Single
Model part of larger framework
Incorporated models or components:
Spatial dimensions 2D
Spatial extent
Model domain Coastal
One-line model description 2D long-term marsh evolution model based on tidal dispersion
Extended model description Simulate marsh evolution at 10-10000 time scale. Suitable for domains 0.1km2 to 1000 km2.

Only simulates tidal flow. Conserve sediment within the domain. Allows to track sediment through the open boundaries.
