A growth model for water distribution networks with loops

Abstract: Water distribution networks (WDNs) expand their service areas over time. These growth dynamics are poorly understood. One facet of WDNs is that they have loops in general, and closing loops may be a functionally important process for enhancing their robustness and efficiency. We propose a growth model for WDNs that generates networks with loops and is applicable to networks with multiple water sources. We apply the proposed model to four empirical WDNs to show that it produces networks whose structure is simil… Show more

“…A conceptual framework for the water distribution scheme is proposed [14], which builds looped networks and is suitable for systems with numerous water sources. The proposed methodology is used to four actual networks to demonstrate that it generates networks with comparable architecture to the actual ones.…”

“…simplicial complex expands over time [15,16,17]. This arises in numerous applications, for instance, predicting the water flow in a new pipe between hydraulic components of a water network [18], providing a global ranking where new alternatives are coming over time in statistical ranking, or predicting the exchange rates in a financial market where a new trade between two commodities establishes over time [6,10]. Nevertheless, existing methods [19,13,20] only process simplicial signals on static settings and do not capture the expanding nature of the topology.…”
