This report presents methodology for designing weir sand-bypassing systems. Jetties are generally shore-normal structures built at tidal inlets to fix the location of the inlet and associated navigation channel. In a weir-jetty system one or both jetties is constructed with a low weir section across which sediment can move into a deposition basin. The sediment caught in the excavated deposition basin is periodically dredged and bypassed to downdrift beaches to preclude serious erosion of those beaches. The design of a weir bypassing system requires knowledge of the wave and sand transport conditions at a site and involves locating and proportioning the jetties, weir section, deposition basin, and navigation channel, as well as selecting and designing the desired updrift and downdrift beach configuration. Methods of data analysis and interpretation for weir-system design are presented along with guidance on proportioning the various components of a weir bypassing system.
