Proposal of management framework for coping with potential soil and groundwater contamination in a watershed to influence its rivers and lakes

Abstract

In this research, we proposed a management framework for coping with the contamination in public water areas such as rivers and lakes due to chemical compound leakage to soil and ground water in their watershed. As a fundamental tool for the management, we developed the system of making a simulationbased map of substance flows transported by ground water around a public water area. The map enables river administrators to appropriately take various measures in both a precaution stage and a stage after a leakage.
