Abstract
This report shows how the relationship between relative hydraulic conductivity and soil water content, together with the soil water characteristic curve, was related to a soil water diffusivity D of constant value. The dissimilarity of such so-called linear soils from other soils is manifested by a special relation that exists between the unsaturated hydraulic conductivity and the soil water content, rather than a special relation for their soil water characteristic curves. The derived relationships can be used when the results of numerical methods are tested by analytical procedures.
