USGS scientists have installed video cameras pointed at beaches on the coasts of western Florida and central California. They’re analyzing the videos to measure features of the beach and ocean so they can improve coastal-change forecasts.
Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?
