Example 3.E - Graf Assume a channel with uniform flow at a depth of 5.03 m. Channel is rectangular with a width of 9 m and average velocity of 12 m/s. After a straight reach, the channel makes an a = 60o curve with ro = 100 m. How much super-elevation is expected?

Solution Methodology Note that for a rectangular channel: Dh = A/B = (Bh)/B = h Need the determine if flow is supercritical: Determine b:

Solution Methodology Determine q: Calculate maximum and minimum water depths:

Solution Methodology Another solution for super-elevation:
