and y1 30 cm but the channel slope is not equal to 1°.
Determine the proper slope for this condition.
No doubt you used the horizontaljump formula (10.43)
to solve Probs. 10.89 and 10.90, which is reasonable since
the slope is so small. However, Chow [3, p. 425] points
out that hydraulic jumps are higher on sloped channels,
due to “the weight of the fluid in the jump.” Make a con  v v P10.90  eText Main Menu  Bump: h = 10 cm P10.95

P10.97 A brickwork rectangular channel 4 m wide is flowing at
8.0 m3/s on a slope of 0.1°. Is this a mild, critical, or
steep slope? What type of gradually varied solution curve
are we on if the local water depth is (a) 1 m, (b...
