Question 1 The sketch below represents a trapezoidal open channel used to manage storm water in A small town in KZN that contributes a discharge Q of 30 m³/sec. The channel base width is 1.5m and has side slopes of 1:2 and a bed slope of 1.5%. Use manning's coefficient (n) = 0.015. Estimate the height of the water after the heavy rain by using the Bisection method. The water height is between 1 m and 2 m. Do five (5) iterations Water level Useful formulae: A* Q = ² * R ³ * S² n h R = 4 (Area/wetted perimeter) Note: For this channel section A and P h = height of water (requires estimation) b = bottom width of channel (1.5 m) are given by Sketch not to scale A = bh + 2h² P = b + 2hv1 + 2²

A horizontal channel with a trapezoidal cross-section has a bottom width of 5 m, sidewall slope of 1V:2H, and discharge of Q = 10.85 m³/s. The water level was kept constant at the gate to 0.25 m to form a hydraulic jump in the channel. The conjugate depth based on the graphical method (Figure 6-7) is: Select an answer and submit.

Solve the the problem with drawing.
“ANS” is the professor’s provided answer.
A rectangular channel with a width of B = 2 m drains water with a discharge of Q = 2,4 m3/s. The depths of water at an adjacent point are 1,5 m and 1,4 m. If the Chezy coefficient is 50 and the slope of the Io channel base = 0,0004, calculate the distance between the two faces. Continue to normal depth with the direct step method.
