2. A 15mm rainfall is recorded over a small catchment according to the table below. Infiltration tests in the area have given the following Horton equation parameters: a. Calculate the infiltration capacity as a function of time. It is assumed that the soil surface is always ponded with water. Can the Horton equation be applied to calculate infiltration for this rainfall event? fo=27 mm/hr, f.=6 mm/hr; k=3.5 hr. %3D

2. A 15mm rainfall is recorded over a small catchment according to the table below.
Infiltration tests in the area have given the following Horton equation parameters:
a. Calculate the infiltration capacity as a function of time. It is assumed that the soil
surface is always ponded with water.
Can the Horton equation be applied to calculate infiltration for this rainfall event?
fo = 27 mm/hr, f=6 mm/hr; k=3.5 hr.
