Land use planning in unstable areas: Ventnor, Isle of Wight
Recent UK Government guidance has emphasized the need to take account of landslide problems in the land use planning process (DoE 1990, 1996). To assist the implementation of this policy, the then Department of the Environment (DoE) commissioned a number of demonstration projects to develop approaches to assess the potential for landsliding and to identify the best ways of in corporating this information in the planning process.
In the UK there are many situations where historic development has resulted in the concentration of urban development and infrastructure on unstable ground. This is often on a scale such that total avoidance or abandonment are out of the question, as is recourse to large-scale and inordinately expensive engineering solutions (e.g. the Bath area, Lyme Regis, the South Wales valleys, etc. (Jones & Lee 1994)). Under these circumstances, detailed knowledge of slope instability is required so that pragmatic policies can be developed to assist communities to reduce risk. This approach has been pioneered by the detailed study of the Undercliff at Ventnor, on the south coast of the Isle of Wight, England (Lee & Moore 1991; Lee et al.1991a, b, c;Moore et al 1991).
Figures & Tables
This volume presents a collection of papers on techniques and case studies in land surface evaluation for engineering practice written by specialist practitioners in the field. The volume arose out of deliberations by the Second Working Party on Land Surface Evaluation set up by the Engineering Group of the Geological Society in January 1997 and chaired by Dr. J. S. Griffiths. The book examples of cost-effective methods for collecting land surface and near surface data prior to carrying further detailed ground investigations of engineering geologist, geotechnical engineers, geomorphologist and planners who have the responsibility for planning a designing investigations of potential sites of development.
