Abstract: A supercritical concrete channel is proposed for Mission Creek located in Santa Barbara County, California. The proposed channel may transport gravels and cobbles as bed load during large flood events. Physical and numerical modelling are currently underway to determine the effect of the bed-load transport on the hydraulic roughness of the proposed channel. Preliminary results indicate a slight increase in hydraulic roughness with increased bed-load concentration. Formation of bed forms has not occurred for concentrations of less than 3000 ppm.
