Abstract

Abstract

The second-order accuracy of several well-known integral estimates of the sorptivity is shown to be limited to a particular class of rapidly varying diffusivities. This class includes the exponential and power-law diffusivities commonly used in the description of soil-water flow. The derivation of the sorptivity estimates and the argument for second-order accuracy are clarified and a new formula for the sorptivity is derived that applies to a wider class of diffusivities.
