Determine the section factor (Z) of a triangular channel with right angle corner (900) with a depth of 3 meters.

Assume the following channel slopes occur in a prismatic open channel depicted in Figure 5. Note where the water surface begins on the left. Number the water surface curves with a 1 if the water surface is above both ye and yo, 2 if the water surface is between ye and yo, and 3 if the water surface is below both ye and yo. Figure 5: Engineered channel profile view Determine • Label ye and y, for each reach (state if y, is infinite). Label the bed slopes. • Label the control points. • Draw a possible gradually varied flow profile and label all the curves (letter and number). ● Free overfall

What is the critical depth corresponding to a discharge of 5.0 ems in a trapezoidal channel of bottom width 0.5 m and side slope 1.0 Horizontal: 1.0 Vertical? 2) Similarly, what is the critical depth in a circular channel with a diameter of 1.75 m carrying a discharge of 5.0 ems? (Hint: Use graphical methods).

What is normal depth? Explain how it is established in open channels.

ind the depth of trapezoidal channel of bed width 4m,bed slope of channel is 0.00059,and side slope of 2 horizontal to 3 vertical,when the discharge through the channel is 20 m³/sec.Manning's N=0.03. P 4m
