In a steep mountain stream with a catchment area of 0.7 km², bedload transport has been continuously monitored by an indirect measuring method for seven years. Limitations and potentials of this method are discussed. The main factors influencing the total sediment yield during a single flood event are shown to be the flood water volume, the peak flow and the threshold discharge at the beginning of bedload motion. A prediction equation for the total sediment yield per flood event is proposed. A comparison is made with a bedload transport formula developed from experiments in the hydraulic laboratory.
