CIV E 530 - OPEN-CHANNEL HYDRAULICS FALL 2012 - MIDTERM 1 - SOLUTION

PROBLEM 4

a.

If the flow is unsteady, it cannot be uniform. Uniform flow has constant depth and velocity in time and space. Unsteady flow is changing the depth and the velocity with time and space.

---

b.

Gravity, friction, pressure gradient, and inertia.

---

c.

W/D > 10

---

d.

Under Chezy friction, the neutral-stability Froude number is 2.
Under Manning friction, it is 1.5.

---

e.

Minimun n= 0.008 --- acrylic glass.
Maximum n = 1 --- Everglades flow modeling.
