Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Incorporated models or components: Spatial dimensions 2D Spatial extent Regional-Scale, Landscape-Scale, Watershed-Scale Model domain Coastal One-line model description 2D long-term marsh evolution model based on tidal dispersion Extended model description Simulate marsh evolution at 10-10000 time scale. Suitable for domains 0.1km2 to 1000 km2. Only simulates tidal flow. Conserve sediment within the domain. Allows to track sediment through the open boundaries. Version 2.0 also included wind waves, ponding, edge erosion Version under construction includes swell waves, cross-shore and along-shore wave-induced transport, secondary flow in channel bends, stratigraphy (sand and mud as separate constituents) Keywords: First name Giulio Last name Mariotti Type of contact Project manager Institute / Organization Louisiana State University Postal address 1 Postal address 2 Town / City Baton Rouge Postal code 70803 State Louisiana Country United States Email address gmariotti@lsu.edu Phone Fax Supported platforms Windows Other platform Programming language Matlab Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2017 Does model development still take place?
