A channel transitions from a width (b 1 = 1.5 m) and anelevation of z 1 = 0 m to a width (b 2 ) an elevation of z 2 =+0.08 m. In other words it is going up a step of Δz = 0.08 m andsimultaneously expands in width. The upstream depth y1 = 0.6 m andthe flowrate in the channel is Q = 1 m 3 /s. This channeltransition is specifically designed so that the water stays at thesame depth throughout.
Calculate the width b 2 required to satisfy theseconditions.
