Summary To interpret experimental results from installations of horizontal piezometers for the purpose of obtaining in situ estimates of hydraulic conductivity of saturated soils below the water table, shape factors for a range of cylindrical cavities at the ends of piezometers were obtained using an electric analogue. Those for the particular piezometers used in a field experiment in a clay soil were obtained in the same way and found to be smaller because of the limited number of perforations in the tip forming the cavity. Hydraulic conductivity values obtained with the piezometers were similar to those obtained in laboratory measurements on undisturbed cores of the same soil.
