Sea Level Rise – 5 feet

Six Marin County SLR Scenarios are derived from CoSMos, which combined global climate and wave models with projected sea level rise to identify areas that could be flooded.Coastal Storm Modeling System (CoSMoS) was created by the CoSMoS project team led by Patrick Barnard at the USGS Pacific Coastal and Marine Science Center. CoSMos data is available for free download on the Our Coast Our Future website. CoSMos is releasing data as it is completed: v2.0 covers the Central California outer coast from Half Moon Bay to Bodega Bay; completed December 2012. CoSMoS v2.1 covers inside San Francisco Bay; completed June 2014. Marin County staff processed these datasets to combine the coast and bay datasets into one dataset for each of the six scenarios. Scenario 1: 25 cm / 10 in No storm surge Scenario 2: 25 cm / 10 in + 100-yr Storm Surge Scenario 3: 50 cm / 20 in No storm surge Scenario 4: 50 cm / 20 in + 100-yr Storm Surge Scenario 5: 150 cm / 60 in No storm surge Scenario 6: 150 cm / 60 in + 100-yr Storm Surge Original data was renamed and re-projected from UTM to State Plane coordinate system.Original GIS file names of the six scenarios: Scenario 1: SLR025_W000 Scenario 2: SLR025_W100 Scenario 3: SLR050_W000 Scenario 4: SLR050_W100 Scenario 5: SLR150_W000 Scenario 6: SLR150_W100 BayWAVE website: marinSLR.org OCOF website: ourcoastourfuture.org马林县的六个海平面上升（Sea Level Rise，SLR）情景数据集源自海岸风暴模拟系统（Coastal Storm Modeling System，CoSMoS）。该系统将全球气候模型、波浪模型与预测海平面上升数据相结合，用于识别潜在洪涝淹没区域。海岸风暴模拟系统（CoSMoS）由美国地质调查局（United States Geological Survey，USGS）太平洋海岸与海洋科学中心Patrick Barnard领衔的CoSMoS项目团队开发完成。CoSMoS数据集可在Our Coast Our Future（我们的海岸我们的未来）官网免费下载。CoSMoS按完成进度逐步发布数据：v2.0版本覆盖加利福尼亚州中部外海岸（半月湾至博德加湾海域），于2012年12月完成；v2.1版本覆盖旧金山湾内部水域，于2014年6月完成。马林县工作人员对上述数据集进行处理，将海岸与海湾数据集整合为对应六个情景的单一数据集。六个情景具体如下：情景1：海平面上升25厘米（10英寸），无风暴潮；情景2：海平面上升25厘米（10英寸）叠加百年一遇风暴潮；情景3：海平面上升50厘米（20英寸），无风暴潮；情景4：海平面上升50厘米（20英寸）叠加百年一遇风暴潮；情景5：海平面上升150厘米（60英寸），无风暴潮；情景6：海平面上升150厘米（60英寸）叠加百年一遇风暴潮。原始数据已完成重命名，并从通用横轴墨卡托（Universal Transverse Mercator，UTM）坐标系转换至州平面坐标系。六个情景的原始GIS文件名如下：情景1：SLR025_W000；情景2：SLR025_W100；情景3：SLR050_W000；情景4：SLR050_W100；情景5：SLR150_W000；情景6：SLR150_W100。相关平台网站：BayWAVE平台：marinSLR.org；OCOF平台：ourcoastourfuture.org。
