USGS and NASA researchers meet to discuss Synthetic Aperture Radar for assessing USGS coastal-flooding projections

Release Date:

USGS and NASA researchers met July 16 at NASA’s Jet Propulsion Laboratory (JPL) to discuss Synthetic Aperture Radar (SAR) imagery of the Southern California coast collected during higher-than-normal tides (“king tides”) in fall 2016.

USGS and NASA researchers met July 16 at NASA’s Jet Propulsion Laboratory (JPL) to discuss Synthetic Aperture Radar (SAR) imagery of the Southern California coast collected during higher-than-normal tides (“king tides”) in fall 2016. JPL collected the SAR imagery to determine if it could be used to validate and improve coastal flood hazard simulations made by the USGS Coastal Storm Modeling System (CoSMoS). Volunteers with Urban Tides, a community science initiative with USC Sea Grant, took shore-based photographs on the dates of the SAR flights, providing  on-the-ground comparisons. USGS and JPL researchers met to discuss the initial analyses of data extracted from the SAR overflights, and the ability to use these data for validating CoSMoS king tide projections.

Coastal Storm Modeling System (CoSMoS)

The Coastal Storm Modeling System (CoSMoS) makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales. CoSMoS was developed for hindcast studies, operational applications and future climate scenarios to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety...
