Flow pattern formed over steps at a low-head dam: Salmon River Dam
Building Stepping way over the low-head dams has been proposed to reduce the risk of drowning in submerged flow conditions. In the Salmon Barrier, adding two steps downstream of weir was previously suggested as an effective method for reducing the risk ...

The effect of crest shape on discharge coefficient at linear weirs
A detailed experimental laboratory analysis of the effect of crest shape on the discharge coefficient of sharp-crested weirs is presented in the paper. The experiments were conducted for four different crest shapes. The experiments and analyses show that

Hydraulic Performance of Sharp-Crested Labyrinth Weir
Weirs are used as a control structure in the waterways. Among the influencing geometrical parameters on the weir performance is the total crest length. Experimental work on 27 geometric models of two-cycle Labyrinth shape crest weir is tested. The tested physical models consist of three weir heights, three apex widths and the sidewall angle is between (

Numerical modelling of flow over sharp-crested rectangular contracted weir [PDF]
Weirs are flow control structures that can be used for flow diversion purposes. They are classified according to section geometry or their length in the flow direction.

Numerical Investigation of Geometric Parameters Effect of the Labyrinth Weir on the Discharge Coefficient [PDF]
Weirs, as overflow structures, are extensively applied for the measurement of flow, its diversion, and control in the open canals. Labyrinth weir as a result of more effective length than conventional weirs allows passing more discharge in narrow canals.

Overflow Characteristic of Cylindrical Shape Crest Weirs over Horizontal Bed
The most common types of weirs are the broad-crested weir, the sharp-crested weir, the circular crested weir and the ogee crested weir. Advantages of the cylindrical weir shape include the stable overflow pattern, the ease to pass floating debris, the ...

Experimental study of discharge Coefficient of Piano Key Side Weir in 45-Degree Sector of a curved channel [PDF]
A new type of Long-crested weirs is Piano Key weir that allows the reservoir to run at a higher level. The use of a Piano Key weir as side weir allows for more drainage, due to the geometric shape of the channel and the impact of centrifugal force on the
