Bedload conditions the development of river morphology along different space and time scales; however, by concentrating the flow in preferential paths, a given morphology controls bedload for a given discharge. As bedload is a non-linear response of shear stress, local morphology is likely to have a strong impact on bedload prediction when the shear stress is averaged over the section, as is usually done. We will see how taking into account the river morphology can help to improve bedload prediction. But on the other hand, predicting the morphology also requires predicting the size of the transported material, and from this point of view, we will discuss the limitation of available computational methods in a morphodynamics perspective.
Bio :
Alain Recking is researcher in the Torrent Erosion and Snow Avalanches group at Irstea, in Grenoble. His research focuses on fluvial-hydraulic processes in gravel- and cobble-bed channels, including grain sorting and feedbacks between flow hydraulics, sediment transport, and morphodynamics. He teaches every years Hydraulic and Sediment Transport in several Universities as well as for staffs of several government agencies.
