SURF AND NEARSHORE DYNAMICS CAMERA (SANDCAM) AT REHOBOTH BEACH, DELAWARE

PURPOSE

The purpose of this project is to use video-based remote sensing to quantify changes in the beach planform area over time. The methodology follows/utilizes the pioneering work of Rob Holman (THANKS!) to quantify what is seen in imagery overlooking the beach. There are presently 3 sites installed on the Delaware or New Jersey coast (Rehoboth Beach, Bethany Beach (Kirby's cameras), Cape May). In the near future, an additional site will be installed in New Jersey and one at Cape Henlopen in Delaware. to see the imagery click here.

The image below shows a merged time exposure image from Rehoboth Beach covering approximately 6 km in the alongshore and several hundred meters in the cross-shore.

This image shows the mean shoreline over several seasons at Rehoboth Beach after correcting for tidal variations. The net change at this site over roughly 1 year was ~1m.
