The Hydraulic Conductivity-Water Content Relationship During Nonsteady Flow Through a Sand Column1

  1. J. S. Rogers and
  2. A. Klute2



Water contents and hydraulic heads were measured for three rates of draining and rewetting a vertical column of sand. Fluxes of water determined from the water content data and hydraulic gradients determined from the hydraulic head data were used in Darcy's Law to determine hydraulic conductivity. The hydraulic conductivity was a single valued function of the water content exhibiting no hysteresis. There was no relationship between hydraulic conductivity and the rate of change of water content although a rate dependent water content-pressure head relationship was present in the data.
