AN INTEGRATED EVALUATION PROGRAM FOR THE ASSESSMENT OF VARIATIONS IN URBAN GROUNDWATER LEVEL

摘要

Bridging the gap between a need for preserving unique historic cities and a requirement for modern infrastructure development is one of the major challenges for sustainability of urban areas. Many historic cities around the world have complicated ground conditions, commonly represented by weak soils and a high groundwater table. Natural, or historically formed, hydrogeological conditions need to be maintained carefully in such ground conditions, since even insignificant variations of groundwater level and gradient may affect valuable historic buildings. This paper discusses an integrated evaluation program for the assessment of causes and consequences of variations in hydrogeological parameters within urban historic environments. An analytical quantitative method based on hierarchy structures is used for the program. Some examples of the potential use of the assessment program in Hamburg and St.Petersburg are given.
