Stepped spillway prototype operation and air entrainment: toward a better understanding of the mechanisms leading to air entrainment in skimming flows

H Chanson - Journal of Hydraulic Engineering, 2022 - ascelibrary.org
A spillway is a conveyance structure designed to pass flood waters. The construction of
steps down the steep chute may contribute to some energy dissipation, in turn reducing the …

Environmental fluid mechanics of minimum energy loss weirs: hydrodynamics and self-aeration at Chinchilla MEL weir during the November–December 2021 flood …

H Chanson, CJ Apelt - Environmental Fluid Mechanics, 2023 - Springer
During the recent decades, a number of overflow embankment protection systems were
implemented. One design is the Minimum Energy Loss (MEL) weir, developed to pass large …

Inception line of air entrainment for converging stepped spillways

G Liu, S Qian, J Feng, H Xu, F Ma… - Journal of Hydraulic …, 2025 - ascelibrary.org
In the traditional stepped spillways with uniform width, the inception points of air entrainment
along the spillway transverse direction generally remain at a similar distance from the …

[HTML][HTML] Modelling spillway and weir operation during major overflows. On optical measurements in prototypes: pros and cons

H CHANSON, R SHI - Flow Measurement and Instrumentation, 2024 - Elsevier
At weirs and dams, the spillway flow is a high-velocity turbulent motion operating at very-
large Reynolds numbers and physical measurements are challenging. In these high-speed …

Self-aeration on large dam spillways during major floods

H Chanson - Journal of Hydro-environment Research, 2024 - Elsevier
In a spillway chute flow, the upstream flow is typically non-aerated and the flow becomes self-
aerated when the turbulent stresses acting next to the water surface exceeds the combined …

[HTML][HTML] Numerical Investigation of Different Stepped Spillway Geometries over a Mild Slope for Safe Operation Using Multi-Phase Model

BR Pandey, MR KC, B Crookston, G Zenz - Water, 2024 - mdpi.com
The appropriate design and operation of spillways are critical for dam safety. To enhance
design practices and gain insights into flow hydraulics, both experimental and numerical …

Self aeration and energy dissipation on a steep stepped chute: how does physical modelling compare to prototype observations?

H Chanson, J Hu - Environmental Fluid Mechanics, 2024 - Springer
For the last five decades, a number of overflow stepped chutes were built because the
staircase shape is conducive to reduced construction costs and increased rate of energy …

Uncertainties in Measurements of Bubbly Flows Using Phase-Detection Probes

M Bürgler, D Valero, B Hohermuth, RM Boes… - arXiv preprint arXiv …, 2024 - arxiv.org
The analysis of bubbly two-phase flows is challenging due to their turbulent nature and the
need for intrusive phase-detection probes. However, accurately characterizing these flows is …
