Assume that the time evolution of the infiltration capacity for a given soil is governed by Horton's equation. For this soil, the asymptotic or final equilibrium infiltration capacity is fe 125 cm/h, and the initial infiltration capacity is f=8 cm/h. The rate of decay of infiltration capacity parameter is k = 3 k'. The time rate of change of precipitation is given below.
