Experimental study on the body parameters of the two-stage stilling basin in low Froude number flow
Shui kexue jinzhan, 2018 Under the condition of a low Froude number (Fr) flow, the two-stage stilling basin is an effective way of solving the problem of energy dissipation. However, to date, there have been many applications of the two-stage stilling basin, but little research ...

Hydraulic jumps and stilling basins [PDF]
, 2015 A hydraulic jump is a rapid transition from a high-velocity open channel flow to a slower fluvial motion. It is commonly experienced in streams and rivers, in industrial channels, during manufacturing processes and downstream of dam spillways. The air is entrapped at the jump toe that is a discontinuity between the impinging flow and the roller.

Hydraulic Performance of Wave-Type Flow at a Sill-Controlled Stilling Basin
Applied Sciences, 2023 Downstream of the sluice gate or weir, wave-type flows inevitably occur in stilling basins with no tailwater. This paper aims to investigate the hydraulic performance of wave-type flows at a sill-controlled stilling basin through experimental research ...

Numerical Simulation of Imported Sediment in a Stilling Basin
Frontiers in Earth Science, 2021 Sediment buildup at the bottom of a stilling basin can result in premature drainage of spillway structures and can even lead to dam failure in severe cases. Such failures pose ecological and human safety hazards to downstream areas.

Development of Stilling Basin Models with Appurtenances
International Journal of Engineering and Management Research, 2022 This research paper describes about the experimental work leading to the sustainable hydraulic structures by developing new stilling basin model as compared to USBR VI stilling basin model for pipe outlet using with sills. The experimental study was carried out for three Froude numbers namely 3.85, 2.85 and 1.85 for non-circular pipe outlet ...
