A rectangular, sharp-crested weir with end contractions is 1.4  m long. How high should it be placed in a channel to maintain an upstream depth of 2.35  m for 0.40  m^3 / s flow? I Q=1.83 L^' H^1 / 2 where L^'=L-0.2 H (due to end contractions). 0.40=(1.83)(1.4-0.2 H)(H)^3 / 2 H=0.30  m P=2.35-0.30=2.05  m (height of weir) | Numerade
