Abstract
- The article focuses on the vertical mixing in the unstable layer of sediment-loaded open-channel flow. It states that the time between opposite fluctuations is short to set up a steady velocity. Field data for integral timescales are also presented, as well as the particle turbulent fluctuations. It emphasizes that exponential closures are only useful for shallow channel flows, and adds that a Rousean concentration profile should be used for approximation of deep-water scales.
