Moveable-bed sediment transport experiments in open-circuit flumes require that sand be fed into the flume inlet. Previous sand feeders have required the use of dry sand for accurate input rates. Sand recovery and reuse is necessary in open-circuit simulated-flood experiments now in progress in the W. M. Keck Hydraulics Laboratory, Pasadena, Calif., because of the high transport rates used. The large amount of sand recycled makes drying between experiments impractical, requiring that the recovered sand be fed wet. This paper describes the programmable wet sand feeder developed for these experiments.
