CoSMoS 3.0: Southern California

In progress, preliminary data available fall 2015

An updated Southern California project is targeted for completion in 2016. Preliminary data from a 100-year storm event and several sea level rise scenarios will be available late 2015. Funding provided from the California Coastal Conservancy with additional support from local jurisdictions will stimulate this multi-agency collaboration featuring top coastal and climate scientists from Scripps, Oregon State University, private sector, and USGS.

Model enhancements for Southern California include:

  • Improved system methodology from CoSMoS 1.0 for more accurate flood projections in high-interest embayments and estuaries
  • Long-term coastal evolution projections for sandy beaches and cliffs produced from a collection of state-of-the-art models and extensive historical data
  • Downscaled winds from Global Climate Model (GCM) data for locally-generated seas and surge
  • Discharge from rivers for event response and long-term sediment supply
  • An improved baseline elevation DEM that incorporates recent LIDAR surveys collected by the California Coastal Conservancy.
