摘要：

Warrick's [1975] solution was for general time dependence although the analytical form was for a constant flux or step functions. A new method has been extended to derive analytical solutions of a linearized Richards' equation for arbitrary input fluxes before surface saturation. The new solution also determines the time to surface saturation.
