Sumario: Infiltration is physically described in order to model it as a diffusion stochasticprocess. Theorem M-B 1 is enunciated; whose main objective is the inverse diffusionproblem. The theorem is demonstrated in the specific context of solution injectability,and it is applied to solve the inverse diffusion problem in the presence of Boltzmann’sgroup. The inverse problem of the similarity exponent is solved following group analysismethods. The dispersion of a water drop in a three-dimensional porous medium isapplied; a result which in turn is applicable to drop irrigation.Keywords: inverse problems, group analysis of differential equations, similarity, fractals,diffusion, porous medium.
