Science Center Objects
Our Coast Our Future (OCOF) is a collaborative, user-driven project providing science-based decision-support tools to help coastal planners and emergency responders understand, visualize, and anticipate local impacts from sea-level rise (SLR) and storms in the San Francisco Bay region.
Our Coast Our Future (OCOF) is a collaborative, user-driven project providing science-based decision-support tools to help coastal planners and emergency responders understand, visualize, and anticipate local impacts from sea-level rise (SLR) and storms in the San Francisco Bay region. As part of OCOF, CoSMoS produced a suite of coastal flooding projections for over 40 combinations of anticipated SLR and storm conditions from Bodega Bay south to Half Moon Bay; results are accessible via interactive maps overlaying infrastructure and ecosystem vulnerabilities.
Scenarios developed for OCOF feature the full spectrum of SLR (0 to 2 meters, 5 meters) and coastal storms (daily to 100-year return) to meet every possible management planning horizon and degree of risk. The daily, 1-, 20-, and 100-year storm events used in this work were derived from numerically modeled wave heights offshore of San Francisco that were driven by 21st century wind projections derived from an ensemble of the latest Global Climate Models (GCMs) developed for the 5th Assessment Report of the Intergovernmental Panel on Climate Change. Those offshore wave conditions, combined with tides and storm surge, are modeled down to the local level using state-of-the-art numerical modeling tools to determine coastal water levels, which are then projected onto a 2-meter Digital Elevation Model (DEM) to estimate the extent of flooding.
