Prediction of the transition nappe/skimming flow on a stepped channel [PDF]
Journal of Hydraulic Research, 1996 On a stepped channel, two distinct flow regimes may occur : nappe flow for low discharges and flat slopes, and skimming flow for larger flow rates. A simple analytical method to predict the onset of skimming flow is presented. The method is based upon the change of momentum direction at the impact of the jet on the downstream step.

Standing waves of the stepped dropshaft in a deep tunnel stormwater system
Water Science and Technology, 2023 The deep tunnel stormwater system, consisting of dropshafts and underground tunnels, is used to alleviate or prevent urban water problems associated with extreme rainfall events. The stepped dropshaft can transport surface runoff to the tunnels with high

Numerical simulation of flow on circular crested stepped spillway
Applied Water Science, 2022 The spillways are one of the most important hydraulic structures used in river engineering, dam construction, irrigation, and drainage engineering projects. Recently, a new type of such spillways with a circular crest has been proposed.

Vortex-Resistance Hypothesis: Large Eddy Simulation of Turbulent Flow in Isolated Pool- Riffle Units
E3S Web of Conferences, 2018 By numerical simulations of turbulent flow in isolated poolriffle units with various riffle heights, four different types of vortices were found and named as follows: surface rollers (SR), corner rollers (CR), ramp rollers (CR), and axial tails (AT ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Experimental Study on Sediment Control in a Lateral Intake Channel by Using a Spur Dike Combined with a Skimming Wall [PDF]
Advances in Civil Engineering and Environmental ScienceWater diversion using lateral intakes often leads to the issue of sediment entering water transmission systems. Failure to control sediment at the intake results in its transfer into irrigation canals and facilities, causing numerous problems in various ...
