Settlement-The Short and the Long of it
Conference Proceeding
McDougall, J. (2011)
Settlement-The Short and the Long of it. In D. Zekkos (Ed.), Geotechnical Characterization, Field Measurement, and Laboratory Testing of Municipal Solid Waste, (76-111). https://doi.org/10.1061/41146%28395%293
Total settlement in municipal solid waste (MSW) landfills can be considerable, from 25% to 50% of original fill thickness (Bjarngard and Edgers, 1990). Some occurs very quickl...
Mass loss and landfilled waste mechanics.
Conference Proceeding
McDougall, J. (2008)
