Chalk is a soluble carbonate rock with extensive karst development. Natural cavityoccurrence initiallyappears to be random. In an area where the degree of influence of all cavityformational factors is similar, but dissolution is focused on one set of joints rather than another, then solution feature occurrence is perhaps random. This might be termed the ‘microscale’ view, measured at a scale of metres. However, if the pattern of natural cavityoccurrence is considered at a ‘macroscale’ level, saymeasured in hundreds of metres or kilometres, then spatial patterns emerge suggesting dissolution is not as random as it might first appear.

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.
