Evaporation from two‐layered soil systems with varying depths to water table is described for steady‐state conditions. The difference in evaporation rate from a system of fine‐textured soil overlying a coarse soil compared to a homogeneous profile of fine‐textured soil may be relatively small. A reversed condition of layers may have a large effect on evaporation rates. It appears that for many practical purposes the presence of inhomogeneities may be of little consequence when the water table is relatively deep. It also appears that a weighted‐average capillary conductivity curve might give satisfactory results in calculating estimated evaporation rates.
