a) Sketch the specific energy curves for the following open
channel flows:
· A hydraulic jump formed in a rectangular open channel
· Flow through a channel width constriction, where the depths
remain subcritical
throughout
· Flow through a sluice gate, where the gate opening is less
than the flow’s critical
depth.
· Flow through a combined channel width constriction together
with an upward
step, where the depth remains subcritical throughout.
b) Define and explain the following terms
· Critical...
