Web13 nov. 2011 · Hydraulic conductivity was measured over a wide range of water content, from 15.0 up to 23.4%, and dry density in the range 1.57 to 1.74 Mg·m − 3. The correlation between hydraulic conductivity of the lime-treated St Quentin silt, the molding water content and dry density of the samples is shown in Fig. 3. Web1 jan. 2005 · Soil hydraulic conductivity is often measured with small laboratory samples. Due to sampling artifacts or spatial variability, small-scale laboratory samples may not yield representative...
Web20 aug. 2004 · The hydraulic conductivity of the sub-crust shows significant changes from the early stage for the silt loam soil, but only at the final stages for the silty clay loam. The initial value of the hydraulic conductivity of the sub-crust drops by more than 50 per cent for silt loam compared to about 35 per cent for silty clay loam. WebThe in situ horizontal hydraulic conductivity determined from these tests is found to be approximately 10 −3 cm/sec. This value is one to three orders of magnitude larger than that of typical silts and clays, and two to four orders of magnitude larger than the vertical hydraulic conductivity measured on core in laboratory permeameter experiments.
