Q1:

The parameters in Horton's infiltration equation are given as, fo = 7.62 cm/hour, fc = 1.34 cm/hour and k = 4.182/hour. For assumed continuous ponding the cumulative infiltration at the end of 2 hours is

A 2.68 cm

B 1.50 cm

C 1.34 cm

D 4.18 cm

ANS:C - 1.34 cm

f(2) = 1.34+(7.62-1.34) * e^(-4.182 * 2).
f(2) = 1.34 cm.
