The Study of Energy Loss in Stepped- Labyrinth Spillways

علوم آب و خاک, 2020
A ‘spillway’ is a structure used to provide the controlled release of flood water from upstream into downstream area of a dam. As an important component of every dam, a spillway should be constructed strongly, reliably and efficiently to be used at any ...

Assessment of submerged floor water jets to minimize the scour downstream from a stepped spillway

, 2021
Because of hydraulic jump, the scour downstream a stepped spillway is the most confusing issue that endangers the overall stability of the spillway. In this paper, thirty-six exploratory runs are described to explore the impact of utilizing submerged ...

Prediction of Energy Dissipation and Length of Jump over Modified Stepped Spillway using Empirical and Adaptive Neuro-fuzzy Inference System Technique [PDF]

Journal of Applied Fluid Mechanics
This study aims to enhance energy dissipation efficiency by introducing an alternative design to conventional stepped spillways. To achieve this, modified stepped spillway (MSS) with reflector were used and analyzed experimentally for energy dissipation ...

Energy dissipation on a stepped spillway downstream of a Piano Key Weir - Experimental study

, 2011
peer reviewedPiano Key Weir (PKW) is a new type of weir showing appealing hydraulic capacities. Its specific geometric features create different interacting flows and jets downstream of the structure.

Recent Advances in Stepped Spillway Design: Air-Water Flow on Stepped Chutes, Embankment Dam Stepped Spillway and Other Considerations [PDF]

, 2004
New experiments were conducted in a large stepped channel with a 22 degree slope operating at large Reynolds numbers. Interactions between free-surface and cavity recirculation were systematically investigated in the skimming flow regime.
