N2 - A bioreactor landfill, where municipal solid waste (MSW) degradation is accelerated by recirculation of liquids, emerges as a promising technology to harvest energy from MSW. Nevertheless, the effect of waste degradation on the properties of MSW is still not well understood. Shear wave velocity (V s) is directly associated with the stiffness of MSW, but such measurements are rare in bioreactor landfills. A combination of the multichannel analysis of surface waves (MASW) and the microtremor analysis method (MAM) has been implemented at six locations in the Smiths Creek bioreactor landfill in Michigan, at different times, in an attempt to assess the spatial and temporal variation of Vs. The results are presented in terms of dispersion curves and Vs profiles. Results to date show spatial and temporal variability of Vs in the bioreactor landfill with Vs values as low as 60 m/s. Vs profiles in this bioreactor landfill appear to be lower than conventional Subtitle D landfills in Michigan. V s profiles at leachate recirculation cells are similar to those at septage recirculation cells.
