Abstract
Analytical approximations of the sorptivity have previously been formulated to be accurate for rapidlyvarying hydraulic diffusivities However investigations have indicated that the diffusitivity of undisturbed field soils varies much less rapidly than that of repacked soils commonly used in laboratory studies In fact for certain soils the diffusivity may decrease with increasing moisture content In the present paper a new analytical estimate of the sorptivity is derived which retains the accuracy of earlier approximations for rapidlyvarying diffusivities while remaining accurate even for constant and decreasing diffusivities
