Beach Erosion Control Methods
The Bedload Sediment Collector allows energy of streams and coastal longshore currents to selectively capture bedload sediment using simple physical principles. Coarse-grained sediment, fine sands to gravel, migrates as bedload, passes through the grate system to collect within hoppers. Finer sediments, silts and clays, and other organic matter, remain in suspension passing unimpeded over the hopper grates. As the hoppers fill, sediment is pumped to a placement area or dewatering site for beneficial reclamation of harvested sediments. The grated hopper of the collector systems allows operators to target particle sizes captured in the internal hoppers of the collector.
