Settlement behavior of landfills plays an important role in the design of landfill closures, in post-closure maintenance, as well as in the design of post-closure development on top of closed landfills. The last item (post-closure development) gains importance as increasing number of developments take place on closed landfills, driven by real estate pressures in urban areas.
Current understanding of settlement behavior of landfills is primarily based on settlement properties of soils, supplemented by field observations. In this research, attempts are made to integrate the results of field observations with settlement behavior of soils. The results of this research are recommended values of parameters that can be used to predict landfill settlement under various conditions. Among special conditions considered in this research are the states of decomposition of the landfill waste and landfills where bioreactor/leachate recirculation is practiced. Case histories and examples of landfill settlement calculations are developed to aid design practitioners.
This research is conducted in collaboration with senior personnel from GeoSyntec Consultants, Inc.
