CoastMorpho2D

Metadata

Also known as	CM2D
Model type	Tool
Model part of larger framework
Note on status model
Date note status model

Incorporated models or components:

Spatial dimensions	2D, 3D
Spatial extent	Landscape-Scale
Model domain	Coastal
One-line model description	Long term 2D morphodynamics of coastal areas
Extended model description	Long term 2D morphodynamics of coastal areas, including tidal currents, wind waves, swell waves, storm surge, sand, mud, marsh vegetation, edge erosion, marsh ponding, and stratigraphy. CoastMorpho2D was used to produce Fig. 8A of Mariotti and Canestrelli (2026). The CoastMorpho2D model includes the MarshMorpho2D model (which was previously uploaded on CSDMS).

Describe processes represented by the model	Tidal currents Sea waves Swell waves Storm surges Tidal dispersion transport Along-wave transport Downslope transport by currents, swell waves, breaking waves, and sea waves Edge erosion Marsh processes Along-shore transport by radiation stresses
Describe key physical parameters and equations	See -G Mariotti, S Murshid, 2018, A 2D Tide-Averaged Model for the Long-Term Evolution of an Idealized Tidal Basin-Inlet-Delta System, Journal of Marine Science and Engineering 6 (4), 154 -G Mariotti, 2020, Beyond marsh drowning: The many faces of marsh loss (and gain) Advances in Water Resources, 103710
Describe length scale and resolution constraints	Spatial resolution from 1 m to 1 km Spatial extent up to hundreds of km
Describe time scale and resolution constraints	Morphological time steps can be on the order of years Time steps shorter than one tidal period are not realistic
