Results of an infiltrometer test on a soil are given below.
Time (min) 5 10 15 20 30 40 60 80 100
Cumulative
infiltration in
mm
21.5 37.7 52.2 65.8 78.4 89.5 101.8 112.6 123.3
a) From this data, plot the curves of Infiltration capacity Vs time and cumulative
infiltration Vs time in a single graph in MS Excel
b) Obtain the parameters of Horton’s infiltration capacity equation to represent the
data set.
