Document Summary
The 10-year idf curve for baton rouge is given as follow: i. 0f =10 in/hr, where i is the rainfall intensity in in/hr and t is the rainfall duration in minutes. If the infiltration for an area in baton rouge can be described by the horton parameters: cf =1. 5 in/hr, and k =0. 15 min-1, and the depression storage is 0. 4 inches. Consider a 10-year 1-hour storm with uniform rainfall intensity in the baton rouge area, use the horton method to calculate ponding time. Continue problem 1, calculate total infiltration at 1 hour. Continue problem 1, calculate total runoff at 1 hour. [hint: total runoff = total rainfall total infiltration depression storage. - 0f =150 mm/h, cf =50 mm/h, and k =3min-1.
