Identifying Vulnerable and Critical Water Distribution Segments
Publication: World Environmental and Water Resources Congress 2020: Hydraulics, Waterways, and Water Distribution Systems Analysis
ABSTRACT
The purpose of this study is to develop a graph theoretic approach to evaluate segment vulnerability and importance (or criticality), so that isolation valves may be more strategically placed and key isolation valves can be identified. The method quantifies reachability from sources to segments for given segment isolation scenarios, allowing identification of critical and vulnerable segments. An important feature of this work is that it distinguishes between true sources (wells, treatment plants) and ephemeral sources (storage tanks) which have limited capacity. The capability to visually identify key segments is another advance presented in this paper. Preliminary results further indicate that the method captures the decrease in segment vulnerability as the number of valves increases in a network.
