A regional sediment budget for St. Augustine Inlet and St. Johns County, Florida, was developed for the 1999 to 2010 period. Development of the sediment budget had three main objectives: characterize the transport pathways and magnitudes for the 1999 to 2010 period, compare to an earlier sediment budget for 1974 to 1995 (Srinivas and Taylor 1998), and provide input to numerical modeling of the region (Reports 2 and 3, Beck and Legault 2012a,b). An innovative method was developed to create an inlet sediment budget using high quality measured volume changes for an inlet and beach system. Methods described in the Coastal Engineering Manual (CEM-V-6 2008) and Bodge (1999) were applied to determine the extent of inlet influence along the adjacent beaches, the total inlet sink, and a regional sediment budget for a given set of measured volume changes occurring at St. Augustine Inlet in northeast Florida, U.S.A.
