Notes - 2

  • The water conductivity LRES_WCND may be included from relevant testing. For tests with natural water content values may come from suitable water collected in boreholes or, where water is added, a combination of in situ values and those of the added water.
  • The method used including the container shape (LRES_CSHP) and test geometry (LRES_PENT) should be included.
