A model approach to total geology

The ground conditions at any site are a product of its total geological and geomophological history. We call this total geological history, it includes stratigraphy, the structure, the former and current geomorphological processes and the past and present climatic conditions.

Geological models provide a way to conceptualise ground conditions and make predictions. They impose structure on the raw data, identify paterns, allow us to draw on experience and published case histories. A site specific geological model is essential to make sense of the total geological history and predict how this will influence the engineering performance of the site during and after construction.

This site specific geological model is based on consideration of the regional and local geological and geomorphological history and of the current ground surface conditions (Fookes, 1997).
