Abstract: The U. S. Army Corps of Engineers, State of California, and various local agencies in California have collaborated to create tools for regional sediment management (RSM). RSM is meant to be a cost effective way of using sediment dredged from harbors and flood control projects to nourish beaches that have eroded, often to human activity and provide necessary shoreline protection to California's coast. This paper discusses the development and application of a GIS-based tool called Coastal Sediment Benefit Analysis Tool (CSBAT) to optimize the placement of sediment from various sources to various receiver beaches that has been developed for specific application to San Diego County in southern California. The tool is designed to function as a planning level screening tool to help decision-makers evaluate sediment disposal scenarios within an efficient, user-friendly GIS environment. CSBAT was designed around five components: sediment sources, receiver beaches, transportation modes, recreational usage, and environmental considerations.
