During the week of March 26, scientists from the U.S. Geological Survey carried out four days of mapping selected beaches and the adjacent seafloor in Santa Barbara and Ventura counties. Results will be compared to surveys from last fall to highlight changes due to winter waves, and to sediment inputs from area streams.

The study area includes Montecito, California, which was devastated on January 9 by debris flows that killed 21 people.

USGS scientists are measuring beach topography and seafloor bathymetry in this area to better understand long-term coastal changes. The researchers will use precision GPS units on backpacks and on an all-terrain vehicle for beach surveys, and personal watercraft equipped with GPS and sonar for bathymetry surveys. This will be the first comprehensive beach and nearshore survey since the Montecito debris flows on January 9, which was the first major sediment input to Santa Barbara beaches since 2005…

When Santa Barbara County dumps tons of mud from the catastrophic debris flow of January 9 on the shores of Goleta and Carpinteria, this wasn’t like anything that’s happened before. So residents are asking, “Will there be long-term effects? Might there be other locations that can share the impacts..?”
