The 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. Marin County staff processed these datasets to combine the coast and bay datasets into one dataset for each of the six scenarios. This data shows flooding extent of Scenario 1: SLR of 25 cm / 10 inches; No storm surge.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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.
