Turbulence in Open-Channel Flows
TL;DR: A review of open channel turbulence, focusing especially on certain features stemming from the presence of the free surface and the bed of a river, can be found in this article, where the statistical theory of turbulence and coherent structures in open channel flows and boundary layers are discussed.
The impact of stress history on bed structure and critical shear stress
TL;DR: In this paper, the relationship between stress history and entrainment threshold for beds of a range of grain size distributions was quantitatively ascertained using high-resolution laser scanning, which revealed vertical settlement, changes to bed roughness and particle repositioning.

Probabilistic Characterization of Sweep and Ejection Events in Turbulent Flows and Its Implications on Sediment Transport
TL;DR: In this article , a conditional velocity decomposition is applied to the available direct numerical simulation (DNS) flow data after uniform momentum zones (UMZs) edges were determined, which can determine the probabilistic characteristics of coherent structures such as the center point, wall-normal length and streamwise length.

Screened poisson surface reconstruction
Michael Kazhdan,Hugues Hoppe +1 more
TL;DR: This work extends Poisson surface reconstruction to explicitly incorporate the points as interpolation constraints and presents several algorithmic improvements that together reduce the time complexity of the solver to linear in the number of points, thereby enabling faster, higher-quality surface reconstructions.

Local Structure Of Turbulence in an Incompressible Viscous Fluid at Very Large Reynolds Numbers
TL;DR: In this article, the velocity components at each point P = (xi, x2, x3, t) of the region G under consideration belonging to the four-dimensional space were regarded as random variables in the sense of probability theory.
