Discrete interface penetration modeling has recently been proposed to quantify the phenomenological domain response to permeants that substantially alter soil's hydraulic conductivity. Analytical solutions are presented here for a dual‐interface model compatible with constant‐head, constant‐flux, or falling‐head permeameter testing. It is demonstrated that the nondimensional transient saturated hydraulic conductivity response K̄( t ) is independent of permeameter design. Solutions are also presented for the transient potential field φ̄( X,t ) and interface locations X̄ 1 ( t ), X̄ 2 ( t ) that would accompany the infiltration episode.
