Curve simulator

The quasi-exact cumulative downward infiltration equations for 1-D and 3-D  infiltration from a disc infiltrometer can be respectively described as (Haverkamp et al., 1994)

or

The following link allows simulating a 1D and 3 D infiltration curve using the complete and simplified equations of the Haverkamp et al. (1994) model.
