Can any one tell me how to how to determine best values of the parameters of Horton's infiltration equation from the datas obtainedfrom infiltration test on a soil using double ring infiltrometer.

Time since start (min) 5 10 15 20 30 40 60 80 100
Cumulative infiltration 21.5 37.7 52.2 65.8 78.4 89.5 101.8 112.6 123.3
(mm)

I don't know anything about Horton's infiltration equation but I know that you can transfer the values for time and cumulative infiltration on an excel spread sheet, graph the results from which you can do a regression analysis for a polynomial, exponential, reciprocal or whatever equation based on your observation of the plot. If I can do it, you can do it
