In a sharp-crested wear, the thickness of the wear should be less than half of the water of wear.

Q= 2/3CdL √2g h3/2.

The thickness of a sharp-crested weir is generally much thinner such as in using a Plate.

B<H/2.
B = thickness of the weir.
H = height of water above the crest of the weir.

The Discharge equation for a sharp-crested weir remains the same as that of rectangular weir & rectangular notch.

Q = 2/3 Cd X b Root of 2g X H2/3.

L=H÷2.

Length of sharp, hight of water in the weir.

2L < H.
L < H/2.
= length of sharp - crested weir.
