Abstract

A possible approach to modification of water transfer model in porous medium has been described by taking into account relaxation effects. The model offered has made it possible to solve the problem about propagation of a traveling wave of unsaturated flow, construct saturation profiles and verify the model using experimental data of D.A. DiCarlo. It has been shown that the relaxational Richards's model modification enables us to describe the water transfer process in unsaturated porous media not only in qualitative, but also in quantitative terms.
