Laboratory and In Situ Determination of Hydraulic Conductivity and Their Validity in Transient Seepage Analysis

This paper critically compares the use of laboratory tests against in situ combined with numerical seepage modeling to determine hydraulic conductivity natural soil deposits. Laboratory determination used constant head permeability and oedometer on undisturbed Shelby tube block samples. The auger hole method Guelph permeameter were performed field. Groundwater table elevations deposits different values predicted using finite element compared field measurements assess various test results. Hydraulic obtained by provide predictions that best match groundwater table’s observed location at site. observation indicates determined represents actual conditions better than a setting. differences between can be attributed factors such as sample disturbance, anisotropy, fissures cracks, structure addition conceptual procedural testing methods effects size.
