Leak detection in virtually isolated pipe sections within a complex pipe system using a two-source-four-sensor transient testing configuration

Autor: Martin F. Lambert, Aaron C. Zecchin, He Shi, Angus R. Simpson, Jinzhe Gong

Publikováno v: Journal of Hydroinformatics. 22:1306-1320

Leak detection in complex pipeline systems is challenging due to complex wave reflections. This research proposes a new technique for leak detection in targeted pipe sections within complex water supply pipe systems using controlled hydraulic transie

Bayesian Inverse Transient Analysis for Pipeline Condition Assessment: Parameter Estimation and Uncertainty Quantification

Autor: Martin F. Lambert, Jinzhe Gong, Mark L. Stephens, Angus R. Simpson, Chi Zhang, Aaron C. Zecchin

Publikováno v: Water Resources Management. 34:2807-2820

Strategic pipeline asset management requires accurate and up-to-date information on pipeline condition. As a tool for pipeline condition assessment, inverse transient analysis (ITA - a pipeline model calibration approach) is typically formulated as a

Journal of Water Resources Planning and Management, American Society of Civil Engineers, 2022, 148 (1), pp.15. ⟨10.1061/(ASCE)WR.1943-5452.0001484⟩

International audience; This paper used the fusion of an active-set method (ASM) and an interior point method (IPM), with a Newton method, to solve for the steady-state flows, heads, and outflows of a pressure-dependent water distribution system. The

Extremely Sensitive Anomaly Detection in Pipe Networks Using a Higher-Order Paired-Impulse Response Function with a Correlator

Autor: Wei Zeng, Martin F. Lambert, Aaron C. Zecchin, Jinzhe Gong, Benjamin S. Cazzolato, Angus R. Simpson

Publikováno v: Journal of Water Resources Planning and Management. 147

Detection of anomalies in pipe networks (leaks, blockages, and wall deterioration) is critical for targeted pipe section replacement and maintenance in water distribution systems. A hydraul...

Simpler Is Better—Calibration of Pipe Roughness in Water Distribution Systems

Autor: Qi Zhao, Wenyan Wu, Angus R. Simpson, Ailsa Willis

Publikováno v: Water; Volume 14; Issue 20; Pages: 3276

Hydraulic models of water distribution systems (WDSs) need to be calibrated, so they can be used to help to make informed decisions. Usually, hydraulic model calibration follows an iterative process of comparing the simulation results from the model

Condition assessment of pipelines using a Bi-directional layer-peeling method and a dual-sensor configuration

Autor: Wei Zeng, Martin F. Lambert, Jinzhe Gong, Aaron C. Zecchin, Angus R. Simpson, Benjamin S. Cazzolato

Publikováno v: Journal of Sound and Vibration. 457:181-196

Over the past two and a half decades, hydraulic transients have been proposed and also used to assess the condition of pipeline systems through detection of anomalies such as extended pipe wall corrosion and blockages. This paper proposes a new bi-di
