The CoSMoS system for Southern California has been set up as part of the USGS Southern California Coastal Hazards project. The system consists of several numerical models that generate real-time forecasts of water levels, wave heights, coastal erosion and flooding for a period of up to 3 days in advance. The latest model predictions are posted on this website every 12 hours.
In addition to making real-time forecasts, the CoSMoS system has also been applied to simulate a number of historical storms and hypothetical scenarios.
The objective of the SoCal Coastal Hazards project is to integrate multiple USGS research activities with the needs of external partners such as emergency managers and land-use planners to produce products and information that can be used to create more disaster-resilient communities.
