CoSMoS-COAST: The Coastal, One-Line, Assimilated, Simulation Tool of the Coastal Storm Modeling System
CoSMoS-COAST is a computer model used to predict shoreline change due to waves, sea-level rise, and other local processes.
Features
- Accounts for longshore and cross-shore sand transport and local trends
- Assimilates historical shoreline observations to calibrate and validate the model
- Typically applied to project shoreline change on decadal to centennial time scales
- Run in an ensemble to better characterize uncertainty
- Model output is optionally .kml files, readable in Google Earth
About
CoSMoS-COAST, the Coastal, One-line, Assimilated, Simulation Tool, is a transect-based, data-assimilated “one-line” shoreline model that integrates long-shore and cross-shore transport processes. The CoSMoS-COAST model, initially created as the long-term shoreline change component of the USGS Coastal Storm Modeling System, has been in development for almost a decade. The notable and novel aspects of the current model include (a) ensemble simulation techniques and uncertainty quantification, (b) integration with satellite-derived shorelines, (c) the development of a novel “littoral-cell based” ensemble Kalman filter data-assimilation method and (d) output of .kml files, readable in Google Earth.
