Hydraulic jumps and stilling basins [PDF]
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

Characterization of Hydraulic Power in Free-Stream Installations
The performance of open-channel hydropower devices can be optimized by maximizing the product of their load, hydraulic, and generator efficiencies. The maximum hydraulic power theoretically available must be defined according to the operational scenario ...

Experimental and Numerical Investigation of the Effect of Transition Length on Energy Losses in Gradual Transitions Open Channels Under Subcritical Flow [PDF]
'Transition' is a short hydraulic structure used to change the cross-sectional shape or flow shape. Transitions are commonly used both in the open-channels and natural waterways.
