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. CoSMoS v3.0 for Southern California shows projections for future climate scenarios (sea-level rise and storms) to 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. Model details and data sources are outlined in CoSMoS_3.0_Phase_2_Southern_California_Bight:_Summary_of_data_and_methods (available at https://www.sciencebase.gov/catalog/file/get/57f1d4f3e4b0bc0bebfee139?name=CoSMoS_SoCalv3_Phase2_summary_of_methods.pdf). Phase 2 data for Southern California include flood-hazard information for the coast from the border of Mexico to Pt. Conception to include the Channel Islands. Please read the Summary of Methods 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.

The projections were generated using the latest downscaled climate projections for Southern California and calibrated hydrodynamic models. Data have undergone quality checks and meet standards. Dataset is considered complete for the information presented (as described in the Summary of methods) and will be updated as necessary as improvements are developed. Users are advised to read the metadata record and Summary of methods carefully for additional details. Data are concurrent with topobathymetric DEM locations. Model-derived data are accurate within the limitations outlined in CoSMoS_3.0_Phase_2_Southern_California_Bight:_Summary_of_data_and_methods.

See Summary of methods for information on elevation data and grid structure. 20150228 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 Southern California study area and output comparisons between model versions to determine model accuracy and consistency. See Summary of methods for information on model structure and data used. 20150501 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/II simulations. See Summary of methods for information on model structure and outputs. 20160401 Began Channel Islands simulations for each scenario. Began post-processing Delft-3D and XBeach output within Matlab (v. 2015b) to make spatially cohesive flood projection. See Summary of methods for information on model structure and outputs. 20170701 Metadata was modified to add or correct the Larger_Work section, and to correct the link(s) to the Methods Summary pdf so that it points to the new location of the file.
