1. 2. Write a concise description (using equation when necessary) for each of the following terms: a. Open channel flows b. Froude number c. Gradually varied flows d. Uniform flows e. Momentum function f. Critical depth Specific energy diagram is an important tool and concept in OCH. The diagram explains many flow phenomena. For a rectangular channel, draw its specific energy diagram to illustrate the following (i) conjugate depths, (ii) critical depth, (iii) sub- and supercritical flows, (iv) critical flow, (v) velocity head and pressure head. Draw another two diagrams to illustrate how the flow depth, velocity, and specific energy will change when (1) a supercritical flow approaches an increase in channel bottom elevation, and (2) a subcritical flow approaches a contraction. You should consider all possible scenarios. Please make sure your sketch is clearly readable. Poorly labeled diagrams will result in a zero score.
