Question

2.30. Given an initial rate of infiltration equal to 1.5 in./hr and a final capacity of 0.5 in./hr, use Horton's equation [Eq. (2-42)] to find the infiltration capacity at the

following times: 1= 10 min, 15 min, 30 min, 1 hr, 2 hr, 4 hr, and 6 hr. You may assume a time constant k =0.25/hr.
