Abstract

Computer-aided risk assessment in problems of groundwater contamination George F. Finder, Graciela S. Herrera & William A. McGrath Research Center for Groundwater Remediation Design, College of Engineering and Mathematics, University of Vermont, Burlington, Vermont, 05405 USA 1 Introduction The quantification, assessment and management of risk attributable to ex- posure to groundwater contamination can be facilitated via the effective use of computer-assisted analysis. Computer-assisted analysis, within the context of this work, refers to the use of interactive computing to provide engineering guidance into actions taken in the field. The computational tools that are combined to form the foundation for this approach include groundwater flow and transport models, random fields, and Kalman filters. In this paper we describe how these tools are employed. 2 Problem Definition The goal is to define the concentration distribution of a contaminant of concern (COG) dissolved in g
