Using what has become a celebrated catchphrase, Philip W. Anderson once wrote that
“more is different”(Science, Vol. 177, Issue 4047, pp. 393–396, 1972). First formulated in the …

Pool‐riffle units are naturally occurring topographical elements of rivers. Various hypotheses
have been proposed to describe how the hydrodynamics in pool‐riffle units may lead to …

Particle resuspension is an omnipresent source of aerosols into the environment as the
necessary detachment force to return particles to the atmosphere can arise from a variety of …

Rough-bed open-channel flows (OCFs) are ubiquitous in rivers and canals. However, the
scaling and energy contents of very-large-scale motions (VLSMs) in such flows remain …

Direct numerical simulations at two friction Reynolds numbers (550 and 1000) have been
performed to explore the statistical behaviors of wall-attached motions (WAMs) in open-and …

The vortex shedding topology of a heavy pendulum oscillating in a dense fluid is
investigated using time-resolved three-dimensional particle tracking velocimetry (tr-3-D …

The spatiotemporal evolution of hairpin vortex structures in a fully developed turbulent
boundary layer is investigated qualitatively and quantitatively by using two image methods …

Der Einfluss von kohärenten Strukturen auf den Bewegungsbeginn eines fluvialen
Einzelkorns wurde in einer grundlegenden Studie experimentell untersucht. Zur …

This study focuses on sediment particle entrainment over rough bed surfaces below critical
Shields values. For this reason, experiments in a hydraulic flume were conducted and high …

泥沙起动作为泥沙运动力学和河流动力学的基本问题之一, 对河床演变, 渠道冲刷,
推移质输沙率的确定等都具有重要意义. 受水流紊动, 泥沙颗粒床面位置随机等因素影响 …
