The accuracy of discharge measurements derived from surface velocities are highly
dependent on the accuracy of conversions from surface velocity us to depth-averaged …

Current riverine plastic monitoring best practices mainly consider surface observations, thus
neglecting the underlying distribution of plastics in the water column. Bias on plastic budgets …

Well-resolved direct numerical simulations of turbulent open channel flows (OCFs) are
performed for friction Reynolds numbers up to. In summary, the free surface in OCFs plays …

A theoretically based relationship for the Darcy–Weisbach friction factor for rough-bed open-
channel flows is derived and discussed. The derivation procedure is based on the double …

It is widely acknowledged that streamwise ridges on the bed of open-channel flows generate
secondary currents (SCs). A recent discovery of meandering long streamwise counter …

The structure of free-surface flows in a straight compound channel was investigated in a
laboratory flume, consisting of a central smooth-bed main channel (MC) and two adjacent …

Very-large-scale motions (VLSMs) and large-scale motions (LSMs) coexist at moderate
Reynolds numbers in a very long open channel flow. Direct numerical simulations two-way …

Large-eddy simulations of turbulent flow in partially filled pipes are conducted to investigate
the effect of secondary currents on the friction factor, first-and second-order statistics and …

This paper presents image velocimetry measurements on turbulent flows adjacent to a
permeable bed made of randomly packed glass particles. For measuring flow velocities …

Smooth-walled open channel flow datasets, covering both the direct numerical simulation
