Coastal Processes Study of Santa Barbara and Ventura Counties, California. Final Report to the Beach Erosion Authority for Clean Oceans and Nourishment (BEACON)

摘要

The United States Geological Survey and the University of California, Santa Cruz collaborated on a three-year project (2005-2008) to analyze sediment transport processes and identify coarse-grained, nearshore sediment bodies along the Santa Barbara and Ventura County coastline. Work described in this project was primarily supported by the California Department of Boating and Waterways through a grant from the Beach Erosion Authority for Clean Oceans and Nourishment, and was conducted in collaboration with the United States Army Corps of Engineers, Los Angeles District. This research was designed as a regional study of the Santa Barbara-Ventura County coast, complemented with five localized studies in areas of critical interest. Semi-annual surveys (October 2005 to October 2008) designed to capture maximum and minimum beach volumes and seasonal transport patterns (early fall and late winter) included topographic beach surveys using All-Terrain Vehicles, nearshore bathymetric surveys using the USGS Coastal Profiling System, and grain-size analysis using digital cameras.
