Abstract
The Southern California Beach Processes Study: GIS Applications Track: Ocean, Coastal, and Marine Resources Author(s): Randy Bucciarelli, Julie Thomas, Robert Guza The Southern California Beach Processes Study (SCBPS) is designed to improve our understanding of beach sand transport by waves and currents, thus improving local and regional management of sandy shorelines. Airborne topographic LIDAR is used to survey beaches and cliffs from the Mexican border to Long Beach, California. The surveys, at the approximate times of maximum (fall) and minimum (spring) beach width, are used to quantify alongshore variations in the seasonal cycle of changes in beach width and sand volume. The spatially dense but temporally infrequent LIDAR surveys are supplemented with monthly in-situ surveys at two focus sites, selected for their contrasting exposure to sea and swell. The monthly surveys are conducted using GPS-equipped all terrain vehicles and personal watercraft. ArcGIS is implemented throughout the planning, collection, quality assurance, and dissemination of these datasets.
