3. (2 point) How would you expect a 25-acre commercial development to affect runoff: In a 50 acre forested watershed In a 500 acre forested watershed a. b. Note: This is a conceptual questions to understand the impact of development on a watershed.

Solution

a- it will significantly affect the runoff. the volume of runoff will increase as commerical development will mostly consist of concrete surfaces which has more runoff coefficent than that of soil.hence runoff will increase.

b- runoff will have neglible increment as runoff coefficent of concrete is more than soil but the area of commercial establishment is very small compared to total area.
