Students completing the module should
be aware of the range of problems and treatments associated with major examples of degraded or contaminated land
appreciate how rehabilitation objectives vary and how this influences choice of reclamation option
understand how investigation of engineering and ecological aspects of land rehabilitation may be integrated under realistic conditions.
be familiar with issues of sustainable reclamation to a range of afteruses.
The module consists of an integrated series of lectures and field trips covering the main examples of land degradation and contamination resulting from industrial, mining and civil engineering activities. It describes the sources of these environmental problems, their consequences and the scientific basis of reclamation and remediation to sustainable, 'soft' end-uses.
The lecture course begins with a review of the extent of rehabilitation need in the UK, of the varying objectives for differing end use, of approaches to site assessment and investigation, and of differing national approaches to contaminated land issues. It then deals with the problems associated with particular types of land degradation or contamination and provides an understanding of the science underlying their alleviation.
A number of specific topics is then considered. The causes of extreme acidity are investigated and mitigation measures explained. Hazards associated with the behaviour of metals and organic contaminants are described. Engineering and clean-up approaches to alleviating these hazards are then reviewed. Finally, the management of physically degraded and nutrient deficient soils is considered. Rehabilitation to agriculture, amenity and woodland is described in terms of reclamation and subsequent management. The special problems associated with landfill sites and with conservation end-uses are also considered.
A field visit illustrates examples of particular rehabilitation problems or approaches. Workshops use case studies to demonstrate the practical and economic constraints which influence the selection of rehabilitation option.
