1. 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?

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

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

4. Solution Methodology
Another solution for super-elevation:
