ABSTRACT
The electrical resistivity technique has improved significantly for geotechnical and geoenvironmental site investigations. The resistivity imaging (RI) test has been a very popular site investigation and characterization tool for different geotechnical and geoenvironmental applications over the years. Electrical resistivity is the inverse of conductivity, which decreases with an increase in moisture content. The conduction in municipal solid waste (MSW) is largely electrolytic, and the electrical current is carried by the ions in the pore fluid. Shihada. H utilized landfilled MSW samples to investigate the changes in the electrical resistivity with varying moisture content. The electrical resistivity of 30 landfilled MSW samples was measured at actual field moisture content. Shihada conducted a study using the electrical resistivity of fresh MSW samples, landfilled MSW samples, and degraded MSW. Each of the degraded MSW samples was oven dried and compacted, using the same compaction effort.
