CE 5327 - GEOTECHNICAL PRACTICE FOR WASTE DISPOSAL Homework Assignment # 4 (Due Wednesday, February 16, 2005) 1. 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 level. .
