Document Summary

Tutorial 4: a trapezoidal channel has a bottom width of b=1. 83m and side slopes of m=2 (1v:2h) and it carries a discharge of q=8. 21cms. Suppose the channel is nearly horizontal except that there is a smooth, short upward step in the channel bottom of z=0. 69m. The energy loss due to this step is still negligible. The depth before the step (section a) is 1. 62m. Determine the flow depth over the step (section. B): in a rectangular concrete channel (n=0. 013) of width 2. 0m and slope 0. 0018, the water discharge is 3cms. Determine the width of the throat of the venturi flume such that a hydraulic jump will be formed in the downstream part of the channel with a sequent depth equal to the depth of uniform flow. Calculate the increased water depth at the upstream of the venture flume: a riffle has changed the flows as following.
