Abstract: Purpose: In this Coastal and Hydraulics Engineering Technical Note (CHETN), a depth of closure (DOC) analysis for all of the United States coastlines is presented. The DOC is calculated using Wave Information Study (WIS) hindcast stations along the United States coastlines. The results summarized in this CHETN are available in the form of a spreadsheet on the Coastal Inlets Research Program (CIRP) website ( and are planned to be the initial phase of a larger effort to provide DOC estimates as a publicly available interactive web tool that will also include estimates of sediment mobility. The tool will describe the theoretical boundaries of wave-initiated sediment motion for the United States using a simplified method that does not require numerical modeling of waves as well as the frequency of mobility of sediment placed in the nearshore. The tool can be used to rapidly develop a better understanding of what depth and geographical location sediment may be beneficially placed. For navigation channels the DOC would signal the location where channel infilling would lessen. This tool will be useful for any coastal engineering analysis that requires an understanding of the seaward extent of significant net sediment transport in a region.
