Model:Marsh column model


Marsh column model


Also known as
Model type Single
Model part of larger framework
Note on status model
Date note status model
Spatial dimensions 1D
Spatial extent Point-Based
Model domain Coastal
One-line model description Simulates sediment, roots and carbon accumulating in a 1D marsh profile.
Extended model description A marsh column model designed to (ultimately) be inserted beneath spatially distributed marsh sedimentation models. Tracks surface biomass, subsurface root mass, carbon accumulation and decay (includes both labile and refractory carbon), inorganic sediments, and sediment compaction.

Describe processes represented by the model Sedimentation, compaction, root growth and death, carbon deposition, carbon decay
Describe key physical parameters and equations Many, see Mudd et al. (2009) ECSS v 82(3) 377-389
Describe length scale and resolution constraints Point on marsh surface, depth of modeled column can extend to 10s of meters. Sub cm vertical resolution.
Describe time scale and resolution constraints Daily timestep.
Describe any numerical limitations and issues Model slows down as layers are added making long runs (>2000 years) impractical.

Describe available calibration data sets see Mudd et al. (2009) ECSS v 82(3) 377-389

Calibrated from South Carolina sediment cores
