SUMMARY The profiles of hydraulic conductivity for an Evesham Series and a Denchworth Series soil were measured for saturated conditions in the field when the water‐table was near to the soil surface, making use of existing piezometers installed horizontally from inspection pits. The hydraulic conductivity profiles of both soils were found to be practically the same, decreasing from about 100 mm d −1 at a depth of 0.5m to about 0.01 mm d −1 at 1.5m. At any depth the variation in the measured hydraulic conductivity obtained from different piezometer installations in both soils was as great as that between the two soils. Hydraulic conductivity values of the Evesham soil obtained using piezometers agreed with other published results obtained with the auger‐hole method on the same site. Also the hydraulic conductivity profile to 1 m depth obtained for this soil was the same as that found for a monolith, 0.8 m in diameter, taken from an Evesham soil some 100 km away. The results give encouragement to the possibility of inferring hydraulic conductivity values from soil morphological descriptions.
