Friction-factors for flat-bed flows in sand channels
Method is developed for determining friction factors of open channel flows over flat sand beds in active state of transport; graphical predictor is derived from both field and laboratory data, and is presented in format similar to that of Moody pipe-friction diagram; variation of friction factor with Reynolds number for constant values of ratio of hydraulic radius to median sediment size was found to be much different for these flows than for one-phase flows in rigid-boundary conduits.
