A grass-lined roadside channel (n = 0.02) is triangular in shape with 30° side slopes and a bottom slope of 0.005. Determine the normal depth of flow when the discharge is 5 cfs (ft3/sec). 30°

A triangular channel of side slopes of 1.5 horizontal : 1 vertical has a longitudinal slope of 0.0004 and Manning's n 0.022. When the discharge in the channel is 1.50 m/s, estimate the water surface slope relative to the horizontal at a section where the depth of flow is 1.20 m.

A circular channel (n = 0.013) has a diameter of 4.75 ft and is laid on a slope of 0.5%. The flow rate is 40 cfs . Determine the normal and critical depth.

The triangular channel (cross-section shown below) is made of corrugated steel (n = 0.022) and conducts 10 cfs at an elevation of 1000 ft to an elevation of 900 ft. (a) What is the velocity, V (ft/s), of flow? (b) What length, L (ft), should the channel be for normal flow? (c) What is the channel bed slope, So, to maintain normal flow? 2 ft

Is the flow subcritical or supercritical in a 5 m wide rectangular channel with a discharge of 10 m³/sec? Take So = 0.005, n= 0.014.

A trapezoidal open-channel has a bottom width of 30 ft and side slopes of 2:1 (H:V). The channel is paved with a concrete surface. If the channel is laid on a slope of 0.0001 and carries a uniform flow at a depth of 6 ft, determine: a) the discharge (flowrate) in ft3/s. b) the state of the flow (critical, subcritical, super critical)?

A grass-lined trapezoidal channel has a bottom width of 40.0 ft with 4H:1V side slopes. The channel has a longitudinal slope of 0.0005 and a water depth of 15.0 ft. Compute the discharge rate in the channel for a Manning's "n" value of 0.038.

6.8.11. A diversion gate backs up flow in a 5-ft wide rectangular irrigation channel (So = 0.001, 0.015). The discharge in the channel is 50 cfs. If the depth of flow at the gate is 5 ft, deter- mine the channel and flow classification (e.g., M-2, S-1) upstream of the gate and explain your supporting logic. Then determine the water surface profile by finding the depth of flow at distances of 200 ft, 500 ft, and 1,000 ft upstream of the gate. Use a spreadsheet or appropriate computer software to perform the computations. (See the book's preface for computer software suggestions.) %3D n%3D
