This poster present an experimental investigation of bedload transport in steep slope streams. Accurate technics are used to measure bed elevation and sediment transport rate. The data shows the dynamics of antidunes and the stochastic behavior of bedload ...
Large fluctuations in the sediment transport rate are observed in rivers, particularly in mountain streams at intermediate flow rates. These fluctuations seem to be, to some degree, correlated to the formation and migration of bedforms. Today the central q ...
Among the recent experimental studies focusing on the stochastic nature of bedload transport, some results are particularly intriguing: in experiments in which tagged particles (tracers) are tracked, the statistical moments of the time evolution of particl ...

We demonstrate in this poster the role played by stochasticity in bedload transport on steep slope. Multiscale and multifractal behavior is observed, while long range correlation takes place. ...
The idea of stochastic sediment transport models emerged in the 1930s, notably with the doctoral work of Hans A. Einstein (1936). Einstein's seminal work gave impulse to several stochastic models, which usually led to thin-tailed or bounded distributions f ...
