Determine the slope that would result in 1% difference between
depth in the vertical plane and the depth measured perpendicular to the channel
bottom? Compare this slope to the observation that a channel slope of S0 is generally
considered quite steep for open channel flow.
Q2 The mean velocity of flow in a strem is 1.1m/s/ An observer tossed
a rock into the stream that produced ripples radiating in all directions. The ripples
that propagated directly upstream traveled at a velocity of 0.67m/s in the opposite
direction to the direction of the flowing stream.
a) What is the Froude number of this flow
b) Estimate the depth of flow in this stream.
