CoSMoS (Coastal Storm Modeling System) Southern California v3.0 Phase 2 flood-hazard depth and duration projections: 100-year storm in Santa Barbara County

Maximum depth of flooding surface (in cm) in the region landward of the present day shoreline that is inundated for the storm condition and sea-level rise (SLR) scenario indicated. Note: Duration datasets may have occasional gaps in open-coast sections.
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/5633fea2e4b048076347f1cf?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. Several changes from Phase 1 projections are reflected in many areas; please read the Summary of methods and inspect output carefully. Data are complete for the information presented.

本研究指定的风暴情景与海平面上升（Sea-Level Rise, SLR）情景下，受淹没的现今岸线向陆区域内的淹没面最大深度（单位：厘米）。注：开放海岸区段的淹没时长数据集可能存在偶发缺失。
海岸风暴模拟系统（Coastal Storm Modeling System, CoSMoS）可在数百公里的大地理尺度上，以米级分辨率针对当前及未来海平面上升（SLR）情景，对风暴引发的海岸淹没与侵蚀过程开展精细化预测。针对南加州开发的CoSMoS v3.0版本可提供未来气候情景（含海平面上升与风暴情景）下的预测结果，为应急响应人员与海岸规划者提供关键风暴灾害信息，助力提升公共安全、减轻实体损失，并在复杂海岸环境中更高效地管理与调配资源。
