Problem One: A trapezoidal channel of base width 20 ft and side slopes of 1.5H:1V is laid on a slope of 0.001, at a discharge of 1000 ft/s. Compute the flow and draw the surface profile upstream from the overfall to the region where the depth is 10 percent lower than uniform. Assume a manning n- 0.025 and that critical flow occurs at the overfall. Classify the profile.

02) A long rectangular channel is 3 m wide with Manning roughness of 0.018 and bottom slope of 2%. The channel runs downstream from a reservoir into a free overfall at its end. In the reservoir the water surface level is 1.35 m above the bed of the channel at the entrance. Ignore local loss at entrance. a) Calculate the critical depth, the discharge and the normal depth of the channel. (5/8) b) Sketch the water surface profile in the...

A 7-ft wide channel carrying water with a flow rate of Q =2 ft/s is metered by a V-notch weir with an included angle of 639 into a second unfinished concrete channel of 1/2 the width of the first, and a depth of 1/2 Y. If the vertex of the notch is 0.2 ft from the ground, please answer the following questiohs: A. What is the upstream velocity of the fluid (uniform approximation away from the weir)? B. What is...

Water flows at 11 m3/s in a rectangular channel of width 5 m. The slope of the channel is 0.001 and the Manning roughness coefficient is equal to 0.035. If the depth of flow at a selected section is 2 m, calculate the upstream depth at 500 m from the selected section using the standard step method

Open channel flow must have a surface. Because of the free surface, is the driving force in open channel flow. The application of the equation is most effective to estimate the rapid loss of energy when determining the shape of flow profiles for Rapidly varied flow. Flow in open channels is mainly in the regime. Depth of Flow (y or d) – is the vertical distance of the lowest point of a channel section from the surface. In slope is...

A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.

Q1) Consider a rectangular channel with a constant width b, a) Obtain the equation of water surface profile (dy/dx) as function of Froude number and channel bottom slope in a channel transition assuming that over a short distance Ax, the energy losses can be neglected. b) Using the equation you have obtained, draw the water surface profile if flow is supercritical and if there is a downward step at the channel bed and show your results on the graph of...
