Also known as Marsh Channel and Platform Model
Model type Single
Model part of larger framework
Incorporated models or components:
Spatial dimensions 1D
Spatial extent Reach-Scale, Watershed-Scale
Model domain Coastal
One-line model description A stand alone model for the morphological evolution of an idealized transect across a marsh channel-and-platform.
Extended model description A stand alone model for an idealized transect across a marsh channel-and-platform. The model simulates morphological evolution from sub-tidal to millennial time scales. In particular, the model explores the effect that soil creep (of both vegetated and unvegetated mud) has on channel bank dynamics, e.g., bank slumping. The model is written in Matlab.

Describe processes represented by the model Sediment advection/diffusion

Sediment settling Bed erosion Soil creep Organic sediment production Increase in effective settling due to vegetation Increase in drag due to vegetation

Describe key physical parameters and equations -Creep simulated as a linear diffusion process, with vegetation dependent diffusivity

-Suspended sediment concentration variable in time and space throughout the cross section

Describe length scale and resolution constraints Spatial resolution 0.1-1 m

Cross section generally 100 m wide

Describe time scale and resolution constraints Time resolution ~ 1 minute (it explicitly simulates tides)
Describe any numerical limitations and issues Quasi-static tide propagation. Flow neglected when water depth too small.
