Physical and numerical modeling of water dynamics in soil profile
Original language description
Comparison of observed and numerically simulated water transport inside a large undisturbed soil column is one of important procedures for studies of the water and chemicals movement in soil pore system. A setup for undisturbed soil column experiments was constructed in such a manner that a broad variety of initial and boundary conditions may be applied (Matula et al., 1998b). The undisturbed column of Typic Hapludoll, 0.3 m in diameter and 0.85 m in height was taken in a hard plastic container from thefield to the laboratory. A dripping head equipped with syringe needles was used to create relatively homogeneous irrigation pattern of water over the soil surface. The impulse pump was used to control well the irrigation intensity. The sand tank was connected at the bottom of the soil column to establish pressure head (soil water potential) selected from 0.00 m to -0.90 m. Thus the boundary conditions at the soil surface and at the bottom of soil column were well controlled and defined.
