Describe processes represented by the model	The model calculates changes in elevation and vegetation growth for a hypothetical salt marsh. In each cell, elevation change is calculated as the difference between accretion and erosion. Accretion rates are a function of inundation depth, vegetation growth, and suspended sediment concentration. Water routed according to Rinaldo et al. (1999) scheme. Erosion rates calculated according to excess sheer stress. Channels widen according to a diffusion-like routine where downslope transport is inversely proportional to vegetation. Vegetation grows according to Morris et al. (2002) where biomass is proportional to inundation depth up until an optimum depth. Episodic vegetation disturbance is simulated by removing vegetation from randomly selected cells (Kirwan et al., 2008). Another version of the model treats wave erosion in a simplistic manner (Kirwan and Murray, 2008).
Describe key physical parameters and equations	Key parameters include the rate of sea level rise, suspended sediment concentration, tidal range (which controls vegetation distribution), critical shear stress for sediment erosion, and the period of time that erosion takes place during each tidal cycle. Parameters controlling the growth pattern of vegetation can easily be modified.
Describe length scale and resolution constraints	Domain size is 3 km by 3 km, grid cell is 5 m by 5m.
Describe time scale and resolution constraints	The model explicitly runs on an individual tidal cycle time step, which we scale up to 2 months. But, results most meaningful at timescales greater than a couple years.
Describe any numerical limitations and issues	--

Describe available calibration data sets	Biomass productivity and marsh accretion rates from 1984-present, described in Morris et al. (2002).
Upload calibration data sets if available:
Describe available test data sets	A couple high resolution Pb210 curves that span ~100 years are currently being constructed and used to test model.
Upload test data sets if available:
Describe ideal data for testing	Long term, high resolution (annual to couple years) datasets of marsh accretion. Similar time series of channel characteristics would be useful.

Do you have current or future plans for collaborating with other researchers?	Yes

Is there a manual available?	No
