An experimental study on a large model flume using fiber-optical instrumentation indicated
that the onset of skimming flow is a function of critical depth, chute angle, and step height …

Skimming flows in stepped channels are systematically investigated under a wide range of
channel slopes (5.7°⊠ θ⊠ 55°). The flow conditions of skimming flows are classified into two …

Hydraulic engineering of dams and their appurtenant structures counts among the essential
tasks to successfully design safe water-retaining reservoirs for hydroelectric power …

The roughness Froude number is a relatively new dimensionless parameter that began
appearing in the hydraulic engineering literature in the late 1970s, first for the analysis of …

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 …

Rock and stepped gabion weirs are peculiar hydraulic structures that received relatively little
attention in technical literature. Nevertheless, they can be successfully used for river …

Numerous research contributions have been made on the hydraulic properties for steep,
stepped chutes. Stepped chutes applied to more moderate slopes like those for aging …

Stepped chutes are a standard element in hydraulic engineering. Among others, two basic
problems have not yet been addressed so far. These include the direct spray reduction on …

Dans les chutes étagées, le front de la chute est muni d'une série de marches, de près de
l'arête jusqu'au pied. Comme plusieurs autres configurations d'écoulements à grande …

For maintaining healthy streams and rivers, a high concentration of oxygen is desired and
hydraulic structures act as natural aerators where oxygen transfer occurs by creating …
