TL;DR: In this article, a linear power coupled model is proposed to integrate the differences between hyper-concentrated and dilute flows, a parameterized method combining the sediment size, Rouse number, mean concentration, and flow depth parameters has been used for modelling the sediment profile.

TL;DR: In this paper, three kinds of pier arrangements were tested: two piers in tandem arrangement, two staggered arrangement, and three symmetrically staggered arrangement and the equilibrium scour depth at the downstream pier was shown to be the same as that of the upstream pier at S = 8b, where S is the streamwise spacing or distance between piers.

TL;DR: In this article, an improved Shiono-Knight model (SKM) was proposed to represent lateral flow turbulence and secondary currents in different shapes of open channel, i.e., rectangular and trapezoidal.

TL;DR: In this paper, the effect of naturally formed mobile bedforms on velocities, turbulent intensities and turbulent stresses was analyzed using a two-dimensional particle image velocimetry (PIV) to evaluate the turbulence structure of free surface flow over a fixed (immobile) bed, a weakly mobile bed and a temporally varying mobile bed with different stages of bedform development.

TL;DR: In this article, an analytical model that represents the streamwise velocity distribution for open channel flow with submerged flexible vegetation is studied, and a sensitivity analysis has been conducted to assess the influences of the drag (C D ) and friction (C f ) coefficients on the flow velocity.
