CIV E 530 - OPEN-CHANNEL HYDRAULICS

FALL 2019 - MIDTERM 2 - SOLUTION

PROBLEM 3: ESSAY QUESTIONS

1.

    Because natural water carries a certain amount of sediment, and there is a need for a minimum Froude number (and velocity) to avoid channel clogging.

2.

    So (gravity), Sc (friction), and Froude number (hydraulics).

3.

    So, Sc, 0, + ∞, and - ∞.

4.

    12 profiles; C1 and C3 are horizontal.
