The modern theory of the motion of the water in the soil based on Darcy’s law does not take into account the fact that the particles of the soil can be elastically compressed and extended, assuming that the external forces and the hydrostatic pressure act on the liquid filling these pores only. This simplifying assumption necessitates a correction even in the case of problems on the steady flow of soil water under the influence of given external forces.
