Sažetak
The one-dimensional model of vertical infiltration of water into an unsaturated soil layer is presented in the paper. The stationary boundary condition of constant soil surface watering is used for analysing the dynamics of transition from the unsaturated to saturated state of soil pores. The discretisation of the space and time domain of flow is conducted using the finite difference method. The resulting numerical algorithm is included in the program package MathCAD 14 to enable numerical analysis of filtration flow rate.
