A 105-acre rural drainage area, located in the Eastern Panhandle of WV, consists of three different watershed areas as follows: (Use the Rational Method) Pavement = 50%, earth shoulder = 30% and grass shoulder = 20%, assume 1% slope
If the time of concentration for the drainage area is 30 minutes, determine the peak runoff rate (Q) for a storm of 10 yr frequency.
Submit the following answers:
Time of concentration (TC) =
Rainfall intensity (i) =
Runoff Coefficient (C) =
Q10 =
