Field Measurement of Unsaturated Hydraulic Conductivity by Infiltration Through Gypsum Crusts1

  1. J. Bouma and
  2. J. L. Denning2



Field trials were made to test the use of gypsum crusts in the crust test method for measuring unsaturated hydraulic conductivity (K) in situ. Crusts consisting of mixtures of sand and gypsum were more stable and had more constant hydraulic properties than previously used crusts consisting of various puddled soil materials. Test results of four soil horizons are reported.
