Opis:: In the pressure form of Richards' seepage equation, the differential wa-ter capacity function is used and calculation of its values is necessary to solve the equation. The course of function variability was determined basing on the soil moisture characteristic. To obtain simpler solutions, the water capacity was expressed as a function of moisture. Using van Genuchten and logistic functions, its course for six soils available in the relevant literature was determined. Two sandy soils were used to dis-cuss the water capacity hysteresis and simple formulae were proposed, enabling the coefficient for scanning runs to be determined.

Opis:: This paper presents a different, than commonly used, form of equations describing the filtration of a viscous compressible fluid through a porous medium in isothermal conditions. This mathematical model is compared with the liquid flow equations used in the theory of consolidation. It is shown that the current commonly used filtration model representation significantly differs from the filtration process representation in Biot’s and Terzaghi’s soil consolidation models, which has a bearing on the use of the methods of determining the filtration coefficient on the basis of oedometer test results. The present analysis of the filtration theory equations should help interpret effective parameters of the non-steady filtration model. Moreover, equations for the flow of a gas through a porous medium and an interpretation of the filtration model effective parameters in this case are presented.
