Multichannel analysis of surface waves (Park et al., 1999), commonly called MASW, is a seismic technique used to map the near-surface S-wave velocity structure. It has been applied to a range of geotechnical engineering problems, such as detection of cavities (Miller et al., 1999), the search for bedrock structure (Carnevale et al., 2005), examining water seepage (Ivanov et al., 2006), and monitoring ground improvement (Burke and Schofield, 2008). As a by-product of urban development, industrial and domestic refuge is amassed and deposited in various places, ranging from naturally low ground to abandoned quarries. These places are called landfill sites. As urban development progresses, the landfill sites reach their capacity and become unsuitable for further filling. At that point, a variety of approaches are considered as a means of increasing the capacity. When housing developments creep up to the fill site, more refuse is not welcomed and the land use is reconsidered.
