Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Model domain Coastal 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.

Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability Source code availability (Or provide future intension) Through CSDMS repository Source web address Source csdms web address https://github.com/csdms-contrib/GEOMBEST-plusplus Program license type BSD or MIT X11 Program license type other Memory requirements Typical run time minutes to hours 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 Output format Other output format .mat file Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model See the GEOMBEST++ Users Guide, section 4.
