Abstract : The purpose of the study was to further the understanding of unsteady transport of coarse bedload. A particular focus was the interaction of the load with the river bed material and the effects of transport on stream hydraulics. It was anticipated that new methodology would be developed and that data sets suitable for further modelling would result. The nature of coarse gravel transport through a short reach of a mountain river was examined using novel methodology; primarily, magnetic particle detection; acoustic bedload detection, electromagnetic current meters and fine-resolution bed elevation surveys.
