Summary
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 and future SLR scenarios, as well as long-term shoreline change and cliff retreat. 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, mitigate physical damages, and more effectively manage and allocate resources within complex coastal settings.
Several versions of CoSMoS have been implemented for areas of the California coast, including Southern California, Central California, and San Francisco Bay; see the attached implementation map for details. Further versions will be incorporated as additional regions and improvements are developed.
Data for the various CoSMoS versions and supporting investigations are available on this site (ScienceBase), on the Our Coast, Our Future website (OCOF, ourcoastourfuture.org), and on the CoSMoS website. See the implementation map for details.
These data are intended for policy makers, resource managers, science researchers, students, and the general public. These data can be used with geographic information systems or other software to identify and assess possible areas of vulnerability. These data are not intended to be used for navigation.
This work is part of on-going modeling efforts for California and the western United States. For more information on CoSMoS implementation, see https://www.usgs.gov/centers/pcmsc/science/coastal-storm-modeling-system-cosmos
