This paper describes the field experience acquired with the construction and operation of three sizes of trapezoidal-shaped supercritical flow flumes for measuring water flows from basins discharging large quantities of sediment and debris. A method of computing theoretical discharge ratings is presented and shown to be in close agreement with model and field calibrations. Techniques and precautions in design and placement in stream channels are presented. Commercially available water samplers programmed to optimize sampling with storm hydrograph characteristics can be used to measure sediment concentration hydrographs. With both sediment concentrations and water discharges known for storm runoff events, sediment loads can be determined.
