Date note status model

Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Landscape-Scale
Model domain	Coastal
One-line model description	Geomorphic Model of Barrier, Estuarine, and Shoreface Translations + Marsh + Seagrass
Extended model description	GEOMBEST++Seagrass is a morphological-behaviour model that simulates the evolution of coastal morphology and stratigraphy resulting from changes in sea level and sediment volume within the shoreface, barrier, and estuary. GEOMBEST++Seagrass builds on previous iterations (i.e. GEOMBEST, GEOMBEST+, and GEOMBEST++) by incorporating seagrass dynamics into the back-barrier bay.

Keywords:	barrier island, seagrass, marsh, coastal evolution,

Describe input parameters	Note: See the GEOMBEST++Seagrass Users Guide, section 6 A minimum of four Microsoft Excel files are required to run a simulation: an “erosionresponse” file, an “accretionresponse” file, a “run#” file, and a “tract#” file. If the simulation involves a single coastal tract then the files must be titled “erosionresponse”, “accretionreponse”, “run1” file and “tract1.” Caution: Note that the run# and tract# files will have the same name (tract1, run1, etc.) for all simulations, so attention to organization is critical.
