CoSMoS v3.1 for central California shows projections for future climate scenarios (sea-level rise and storms)

USGS scientists installed video cameras atop a building and oceanographic instruments off San Juan, Puerto Rico, to better understand how waves move across coral reefs and cause flooding on tropical shorelines.

This web page provides files that may be used to run a basic depth-averaged (2DH) Deltares Delft3D version 4.00.01 astronomic tide model for San Francisco Bay. It was developed with the primary aim of assessing water level fluctuations and flow conditions in the vicinity of the Golden Gate (Elias and Hansen 2013).

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

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.

The tsunami that was triggered by a magnitude 8.1 earthquake on September 29, 2009, caused significant damage and loss of life on Samoa, American Samoa, and Tonga. In the hopes that disasters such as this can be minimized in the future, we attempt to understand the mechanism and impact of this tsunami. The information presented here is focused on geologic aspects of the disaster.
