What is broad-crested weir?

Broad crested weirs are robust structures that are generally constructed from reinforced concrete and which usually span the full width of the channel. They are used to measure the discharge of rivers and are much more suited for this purpose than the relatively flimsy sharp-crested weirs.

What are the types of weirs based on shape of the crest?

It is of four types they are, sharp-crested weir, broad- crested weir, narrow-crested weir, and ogee-shaped weir.

FAQ

What is Discharge over a broad-crested weir?
The Discharge over a broad-crested weir formula is known by considering the coefficient of discharge, length, and the head of liquid without the velocity approach and is represented as Q=1.705*Cd*l*(H^1.5) or Discharge=1.705*coefficient of discharging*Length*(head of the liquid^1.5). The coefficient of discharging or efflux coefficient is the ratio of the actual discharge to the theoretical discharge, Length is the measurement or extent of something from end to end and The head of the liquid is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column from the base of its container.
How to calculate Discharge over a broad-crested weir?
