) A watershed experiences a rainfall of 8 inches. What is the runoff volume when the curve number is 80

5.625 inches

Step-by-step explanation:

Given that:

Total Rainfall in inches (P) = 8 inches

The runoff volume (in inches) Q = ???

The curve number CN = 80

Recall that: The runoff volume can be calculated by using the formula:

   for P > 0.2S

Q = 0                     for P < 0.2S

where:

curve number CN = 80

S = 2.5 inches

Since the rainfall (P) is greater than 0.25

Then:

Q = 5.625 inches

Thus, the runoff volume = 5.625 inches

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
