Mass loss and landfilled waste mechanics. (2009)
Presentation / Conference Contribution
McDougall, J. (2009). Mass loss and landfilled waste mechanics.

The impact of mass loss on a particulate medium is investigated. Through a series of laboratory tests on a partly soluble sand, the quantitative impact of mass loss is measured at different applied loads. It is shown that for the material in question...

Landfill modelling challenge: HBM modelling predictions (2008)
Journal Article
McDougall, J. (2008). Landfill modelling challenge: HBM modelling predictions. Proceedings of the ICE - Waste and Resource Management, 161, 147-153. https://doi.org/10.1680/warm.2008.161.4.147

Two laboratory-scale consolidating anaerobic reactors were commissioned, constructed and monitored by Southampton University's waste research group to investigate the long-term behaviour of decomposing waste. The reactor tests were run for 919 days w... Read More about Landfill modelling challenge: HBM modelling predictions.

Geomechanics and Long-Term Landfill Settlement (2008)
Presentation / Conference Contribution

Long term landfill settlement is commonly attributed to two phenomena: creep and biodegradation. Biodegradation, which may contribute the greater proportion of long‐term settlement, is a function of a range of factors, many of which are not easily as...

Assessment of landfill settlement data for evaluation of a hydro-bio-mechanical settlement model. (2007)
Presentation / Conference Contribution
Needham, A., Jones, D. R. V., McDougall, J., Dixon, N., Braithwaite, P., & Rosevear, A. (2007). Assessment of landfill settlement data for evaluation of a hydro-bio-mechanical settlement model.

A hydro-bio-mechanical (HBM) model of waste degradation has been under development for several years to simulate the actual processes involved in the settlement of landfilled wastes. The objective of this current research is the further development o... Read More about Assessment of landfill settlement data for evaluation of a hydro-bio-mechanical settlement model..

Sustainable landfill: the role of fail-safe engineering for landfill aftercare. (2007)
Presentation / Conference Contribution
Hall, D. H., McDougall, J., Drury, D., Blakey, N., Braithwaite, P., & Rosevear, A. (2007). Sustainable landfill: the role of fail-safe engineering for landfill aftercare.

The route to sustainable landfill while adhering to the Landfill Directive requires that ultimately, the waste site will reach equilibrium status. Chemical equilibrium is part of the requirements, but hydraulic equilibrium must also play a role. The...

A hydro-bio-mechanical model for settlement and other behaviour in landfilled waste. (2007)
Journal Article
McDougall, J. (2007). A hydro-bio-mechanical model for settlement and other behaviour in landfilled waste. Computers and Geotechnics, 34, 229-246. https://doi.org/10.1016/j.compgeo.2007.02.004

A conceptual framework for the analysis of settlement and other processes in landfilled waste in relation to coupled hydraulic, biodegradation and mechanical behaviour is presented. The hydraulic model is an unsaturated flow model. The biodegradation... Read More about A hydro-bio-mechanical model for settlement and other behaviour in landfilled waste..
