Natural and managed rivers throughout the world display a wide range of hydrographs that vary in shape from steep and flashy to gradual and consistent, thus influencing the volume and timing of water available for aquatic ecosystems. Although hydrograph shape is an inherent feature of river systems, relatively few investigations have focused on the influence of flow variability on channel grain sizes and bedload transport, and many uncertainties remain with regard to accurately predicting sediment movement during high-flow events. We explored the effects of hydrograph shape on sediment transpo...
