Sorptivity calculation for arbitrary diffusivity

An estimate of the sorptivity that requires only the knowledge of simple integrals of the soil-water diffusivity weighted by a power of the water content is present. The result is checked systematically for diffusivity functions with very different behaviours: power law, exponential and the two Fujita diffusivities. In all cases the error is always less than 1% regardless of whether or not the diffusivity increases rapidly with water content.
