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 fc= 1.25 cm/h; and the initial infiltration capacity is fo=8 cm/h. The rate of decay of infiltration capacity parameter is k = 3 h-1. The time rate of change of precipitation is given below. Compute the rainfall intensity (and plot the hyetograph), infiltration capacity and actual infiltration.

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 fc=
1.25 cm/h; and the initial infiltration capacity is fo=8 cm/h. The rate of decay of infiltration
capacity parameter is k = 3 h-1. The time rate of change of precipitation is given below.
Compute the rainfall intensity (and plot the hyetograph), infiltration capacity and actual
infiltration.
