One-line model description Geomorphic model of barrier, estaurine, and shoreface translations plus dynamic marsh plus waves
Extended model description GEOMBEST++ 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++ builds on previous iterations (i.e. GEOMBEST+) by incorporating the effects of waves into the backbarrier, providing a more physical basis for the evolution of the bay bottom and introducing wave erosion of marsh edges.

marsh, barrier island, wave erosion, overwash, sea level rise,

Describe input parameters Note: See also the GEOMBEST++ Users Guide, section 6

A minimum of four excel files are required to run a GEOMBEST-Plus 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., see below) for all simulations and so attention to organization is critical.

Input format
Other input format Excel
Describe output parameters Marsh boundary - gives the position of the backbarrier marsh edge through time

Shorelines - gives the position of the barrier shoreline through time step number - saves the surface morphology and stratigraphy for the model at each time step
