CoSMoS (Coastal Storm Modeling System) Southern California v3.0 Phase 2 flood-hazard depth and duration projections: 1-year storm in Orange 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.本数据集为给定风暴情景与海平面上升（sea-level rise, SLR）情景下，当前海岸线向陆一侧被淹没区域的淹没面最大水深（单位：厘米）。注意：开敞海岸区段的淹没时长数据集可能存在偶发数据缺失。 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，针对当前及未来海平面上升（SLR）情景，以米级分辨率对风暴引发的海岸淹没与侵蚀过程开展精细化预测。针对南加州的CoSMoS v3.0版本提供了未来气候情景（含海平面上升与风暴情景）下的预测结果，可为应急响应人员与海岸规划者提供关键的风暴灾害信息，助力提升公共安全水平、减轻物理损失，并在复杂海岸环境中更高效地管理与调配资源。 模型细节与数据来源详见《CoSMoS 3.0 第二阶段南加州湾：数据与方法摘要》（可通过https://www.sciencebase.gov/catalog/file/get/5633fea2e4b048076347f1cf?name=CoSMoS_SoCalv3_Phase2_summary_of_methods.pdf获取）。南加州第二阶段数据集涵盖了从墨西哥边境至康塞普申角（Pt. Conception）沿岸的海岸灾害淹没信息。多个区域的预测结果相较于第一阶段已做出多处调整，请务必阅读方法摘要并仔细核查输出结果。本次呈现的信息所对应的数据均完整有效。
