CoSMoS (Coastal Storm Modeling System) Southern California v3.0 Phase 2 flood-hazard projections: 20-year storm in Orange County

Geographic extent of projected coastal flooding, low-lying vulnerable areas, and maxium/minimum flood potential (flood uncertainty) associated with the sea-level rise 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. 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.本数据集涵盖给定海平面上升（Sea-Level Rise，SLR）与风暴情境下，预估海岸洪涝、低洼易受灾区域的地理分布范围，以及洪涝极值与最小潜势（即洪涝不确定性）。 海岸风暴模拟系统（Coastal Storm Modeling System，CoSMoS）可针对当前及未来海平面上升情境，在数百公里的大地理尺度上以米级分辨率精准模拟风暴引发的海岸洪涝与海岸侵蚀过程。针对南加州的CoSMoS v3.0版本，可输出未来气候情境（含海平面上升与风暴）下的洪涝预估结果，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、降低实体财产损失，并在复杂的海岸区域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_Phase_2_Southern_California_Bight：数据与方法总结》（可从https://www.sciencebase.gov/catalog/file/get/5633fea2e4b048076347f1cf?name=CoSMoS_SoCalv3_Phase2_summary_of_methods.pdf获取）。 南加州第二阶段的数据涵盖了从墨西哥边境至康塞普西翁角的海岸带洪涝灾害信息。 本版本相较于第一阶段预估结果，在诸多区域存在多项调整；请务必阅读方法总结文档并仔细核验输出结果。本次呈现的所有数据均完整有效。
