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.
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.
