RISPressure-Leak Duality for Leak Detection and Localization in Water Distribution Systems
Publisher: ASCE
Abstract: Water utilities are challenged to reduce their water losses through detecting, localizing, and repairing leaks as quickly as possible in their aging distribution systems. In this work, we solve this challenging problem by ...
A Robust, Rapidly Convergent Method That Solves the Water Distribution Equations for Pressure-Dependent Models
Publisher: American Society of Civil Engineers
Abstract: In the past, pressure-dependent models (PDMs) have suffered from convergence difficulties. In this paper conditions are established for the existence and uniqueness of solutions to the PDM problem posed as two optimization ...

Reformulated Co-Tree Flows Method Competitive with the Global Gradient Algorithm for Solving Water Distribution System Equations
Publisher: American Society of Civil Engineers
Abstract: Many different methods have been devised to solve the nonlinear systems of equations that model water distribution networks. Probably the most popular is Todini and Pilati’s global gradient algorithm (GGA). Given the GGA’s ...
Absorptive Resilience Phase Assessment Based on Criticality Performance Indicators for Water Distribution Networks
Publisher: American Society of Civil Engineers
Abstract: Water distributions networks (WDNs) are exposed to multiple hazards, leading the network to operate under a range of critical conditions. This paper explored the relationship between the impact of anomalous events (AEs) ...
