Part of: Geographic Information Systems and their Application in Geotechnical Earthquake Engineering


This paper describes the use of a geographic information system to model damage to a municipal water distribution system. In a demonstration application detailed attribute data on components of the water system, such as pipe age, diameter and material, are captured in a GIS database. These data are then used to estimate the probable number of water line breaks based on a set of damage probability matrices. Future extensions and concerns for extending this modeling approach are then discussed.
