摘要: A solution is presented of the linearized Richards equation with inclusion gravity and appropriate boundary conditions describing combined soil-controlled surface evaporation downward infiltration, following application a given amount precipitation or irrigation. This shown to agree available field measurements, namely evolution time zero-flux plane depth rate from bare soil surface. The problem solved by means Green's function method; result general enough be also applicable flow problems in linear soils substantially different ones considered herein.
