Daily Model Calibration with Water Loss Estimation and Localization Using Continuous Monitoring Data in Water Distribution Networks
Publisher: ASCE
Abstract: Due to the increasing deployment of sensors in water distribution networks (WDNs) for continuous monitoring, hydrodynamic data are readily available for engineers to improve the daily operations of WDNs. In collaboration ...
Generalized Acoustic Data Analysis Framework for Leakage Detection and Localization in Field Operational Water Distribution Networks
Publisher: ASCE
Abstract: Detecting and localizing leakages in underground water pipelines continue to be challenging in large-scale water distribution networks (WDNs) having a low density of acoustic sensors per unit pipeline. Many previous acoustic ...
Optimizing Speedup Performance of Computational Hydrodynamic Simulations with UPC Programming Model
Publisher: ASCE
Abstract: In this study, we exploit the advantages of Berkeley’s Unified Parallel C (UPC) programming model to optimize the speedup performance of computational hydrodynamic (CHD) simulations, which constitute an important class of ...
Computational Flood Modeling with UPC Architecture
Publisher: American Society of Civil Engineers
Abstract: Demand for effective flood modeling and forecasting based on the two-dimensional shallow water equations has increased due to uncertainties with climate changes and the need for further accuracy in the urbanized environment. ...
Near Real-Time Anomaly Event Localization by Pressure Drop Interpolation, Clustering, and Parallel Optimization of Hydraulic Model Calibration
Publisher: American Society of Civil Engineers
Abstract: Localization of anomaly events in near real-time (NRT) in water distribution networks is compelling but challenging for water utilities. This paper presents an integrated approach using both data-driven and hydraulic ...
Pressure-Based Demand Aggregation and Calibration of Normal and Abnormal Diurnal Patterns for Smart Water Grid in Near Real-Time
Publisher: ASCE
Abstract: An adequately calibrated hydraulic model is critically to the water distribution digital twin, which requires accurate representation of a water distribution network (WDN) in near real-time. It is thus imperative to construct ...
