Summary Contact Technical specs In/Output Process Testing Other Component info 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).
