In geotechnical characterization of landfill sites it is necessary to determine the permeability or hydraulic conductivity of underlying soil strata. This is generally accomplished through in-situ permeability testing. a Perform an internet survey and hence identify different methods used for in-situ permeability testing. List the name of the test method and reference website URL in a table. b Select two of these test methods and provide a more complete description. Your description should include an illustration illustrations and an explanation of how each of the selected tests is performed and how the data is used to calculate permeability of the soil. Note Do not include those in-situ permeability tests that are used for testing permeability of low permeable clay liners at the ground surface .
