A long wide rectangular channel carries a steady flow rate of 35 m2s-1 (flow per unit width) and passes through an abrupt change in slope from 0.005 (upstream of the change) to 0.003 (downstream).
Water enters a very wide rectangular channel (Manning's n = 0.0149) at a velocity of 12.2 ms-1 and a depth of 0.61 m. An H3 curve forms downstream and the water jumps to a depth of 2.4 m some distan
