CIV E 530 - OPEN-CHANNEL HYDRAULICS

SPRING 2018 - MIDTERM 2 - SOLUTION

PROBLEM 3: ESSAY QUESTIONS

1.

    More, because the permissible shear stress decreases, i.e., the water is hungry for sediment.

2.

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

3.

    So, Sc, 0, + ∞, and - ∞.

4.

    12 profiles; C1 and C3 are horizontal.
