摘要

Periodically changing boundary conditions influence the water flow at the interface of the unsaturated/saturated zone. In this study we investigate periodically time-variant lower boundary conditions in a one-dimensional soil column with a water table, using numerical solutions of Richards equation. The signals used for the simulations are triangular and rectangular wave Functions as well as a sine function with periods ranging from minutes to years and amplitudes of 25,50, and 100 cm. The upper boundary was described by a zero a constant downward flux of 0.01, and 1.0 cm d~-1.
