This data contains geographic extents of projected coastal flooding, low-lying vulnerable areas, and maximum/minimum flood potential (flood uncertainty) associated with the sea-level rise (SLR) and storm condition indicated.
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 sea-level rise (SLR) scenarios. Projections for CoSMoS v3.1 in Central California include flood-hazard information for the coast from Pt. Conception to the Golden Gate. Outputs include SLR scenarios of 0.0, 0.25, 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 3.0, and 5.0 meters; storm scenarios include background conditions (astronomic spring tide and average atmospheric conditions) and simulated 1-year/20-year/100-year return interval coastal storms. Methods and processes used in Central California are replicated from and described in O'Neill and others (2018). Please read metadata and inspect output carefully. Data are complete for the information presented.
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 one portion of ongoing 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

Attribute values are model-derived extents of flood projections, low-lying vulnerable areas, and maximum/minimum flood potential (flood uncertainty) due to plausible sea-level rise and future storm conditions and therefore cannot be validated against observations. The projections were generated using the latest downscaled climate projections for Central California and calibrated hydrodynamic models. See O'Neill and others (2018) for more information.
Data have undergone quality checks and meet standards.
Dataset is considered complete for the information presented (as described in the abstract) and will be updated as necessary as improvements are developed. Users are advised to read the metadata record and cited references carefully for additional details.
Data are concurrent with topobathymetric DEM locations.

GCM data
statistically downscaled Global Climate Model (GCM) data for California
Determined regional 100-year, 20-year, and annual storm events, as well as average conditions for study area. Generated storm-event boundary conditions for Tier I simulations. See O'Neill and others (2018) on CoSMoS framework.
20171201
Obtained topobathymetric DEM data. Set up and populated Tier I/II Delft-3D grids bathymetry from DEM.
20180801
Finished initial grid and FLOW-WAVE model structure within Delft-3D. Finished test storm (January 2010 storm including tides, waves, wind, and pressure) and tide scenarios (no atmospheric forcing, FLOW only) with initial QC checks. Checks included quantitative comparisons to tide station water levels within Central California study area and output comparisons between model versions to determine model accuracy and consistency.
20181030
Began simulations for each scenario. Began post-processing Delft-3D and XBeach output within Matlab (v. 2015b) to make spatially cohesive flood projection. See O'Neill and others (2018) for information on model framework and outputs.
