Where Are the Loops?
Publication: World Environmental and Water Resources Congress 2020: Hydraulics, Waterways, and Water Distribution Systems Analysis
ABSTRACT
Loops in water distribution networks (WDN) provide redundancy. There are surrogate measures of redundancy, quantifying the percentage of actual loops to maximum potential loops for a given network. However, it has been noted in the literature for over three decades that not all loops are equal or contribute to redundancy in the same way. There is a gap in differentiating between WDN layouts with the same percentage of loops, bypassing key network properties. This study applies a method previously used for biological network analysis, to capture more detail on WDN loops. Specifically, this method decomposes the original graph of the WDN to a tree graph, a network model representing loop connectivity. Analyzing such a network model is promising for enhancing the quantification of WDN redundancy and robustness. Measures of loop connectivity are then compared with hydraulic simulation data for benchmark WDN(s).
