The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current and future sea-level rise (SLR) scenarios. CoSMoS version 3.1 for central California shows projections for future climate scenarios (sea-level rise and storms) to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety, mitigate physical damages, and more effectively manage and allocate resources within complex coastal settings.

Data for central California, included in this collection:

  • CoSMoS Central California v3.1 projections of coastal cliff retreat due to 21st century sea-level rise
  • CoSMoS Central California v3.1 projections of shoreline change due to 21st century sea level rise
  • CoSMoS v3.1 - San Francisco County
  • CoSMoS v3.1 - San Luis Obispo County
  • CoSMoS v3.1 - San Mateo County
  • CoSMoS v3.1 - Santa Barbara County

CoSMoS 1.0: Southern California

CoSMoS was initially developed and tested for the Southern California coast in collaboration with Deltares. CoSMoS has been used to assess coastal vulnerability within Southern California for the ARkStorm scenario, the January 2010 El Niño and Sea-Level Rise scenarios, and the January 2005 Newport Harbor Flood scenario.

Dynamic flood modeling essential to assess the coastal impacts of climate change

Coastal inundation due to sea level rise (SLR) is projected to displace hundreds of millions of people worldwide over the next century, creating significant economic, humanitarian, and national-security challenges. However, the majority of previous efforts to characterize potential coastal impacts of climate change have focused primarily on long-term SLR with a static tide level, and have not comp
