Model part of larger framework
Note on status model Development of the model is discontinued and is now merged and fully integrated with CoastMorpho2D (https://csdms.colorado.edu/wiki/Model:CoastMorpho2D)
Date note status model 2024-01-24
Incorporated models or components:
Spatial dimensions 2D
Spatial extent Regional-Scale, Landscape-Scale, Watershed-Scale
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. Version 2.0 also included wind waves, ponding, edge erosion Version under construction includes swell waves, cross-shore and along-shore wave-induced transport, secondary flow in channel bends, stratigraphy (sand and mud as separate constituents)

Describe processes represented by the model Tide-averaged flow (by tidal dispersion)

Flow erosion (assuming quasi-static propagation) Sediment deposition Sediment transport Soil diffusion (aka creep) Organic sediment production Vegetation effect on drag, settling velocity, soil creep Sea level rise

v.20 also includes:

Wind waves (empirical function of speed, water depth, and fetch) Edge erosion Identification of impounded areas Active pond deepening Active pond expansion

Describe key physical parameters and equations Creep coefficient for mud

Creep coefficient for marsh peat Tidal dispersion coefficient Erosion coefficient Critical shear stress for vegetated areas Critical shear stress for unvegetated areas Increase in τcr with depth below MLW Settling velocity in unvegetated areas Settling velocity in vegetated areas Tidal range Tidal period External sediment supply Rate of relative sea level rise Manning coefficient for unvegetated mud Manning coefficient for vegetated areas Maximum organic accretion rate Sediment dry bulk density Morphological time step Spatial resolution

v2.0 also includes:

Time series of wind speed and direction Edge erodibility Fraction of eroded edge material that is oxidized (i.e., removed from the mass balance) Rate of pond deepening Rate of pond expansion Elevation thresholds for pond formation

Describe length scale and resolution constraints Suitable for a large range of spatial resolution (0.5 m to 100 m)
Describe time scale and resolution constraints Generally runs with very large time steps (1 year)

Cannot resolve intra-tidal processes (i.e., ebb-flood variability)

Describe any numerical limitations and issues Implicit code. Very stable. Very efficient
