Coastal Storm Modeling System (CoSMoS)
[Folder View]
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current conditions and future SLR scenarios, and in many locations, there are additional products for long-term shoreline change, cliff retreat, and groundwater hazards. Resulting projections for future climate scenarios (sea-level rise and storms) provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety and mitigate physical damages to reduce risk, and more effectively manage and allocate resources to increase resilience in response to a changing climate within complex coastal settings. CoSMoS has been implemented for the California coast, the U.S. Southeast Atlantic, populated U.S. Pacific Islands, and other locations; see the attached implementation map for details. Data for the various CoSMoS implementations and supporting investigations are available for download either on this site (ScienceBase) or the USGS Coastal and Marine Geoscience Data System (CMGDS, https://cmgds.marine.usgs.gov/). Additional platforms for visualizing the data and analyses include the Our Coast, Our Future website (OCOF, ourcoastourfuture.org, for California only), the USGS Hazard Exposure and Reporting Analytics Tool (HERA, https://www.usgs.gov/apps/hera/), and the USGS Multi-hazard Viewer (https://www.usgs.gov/apps/hera/multiHazardsTool.php).
