RISFaster Inverse Transient Analysis with a Head-Based Method of Characteristics and a Flexible Computational Grid for Pipeline Condition Assessment
Publisher: American Society of Civil Engineers
Abstract: Targeted and proactive pipeline condition assessment is critical for cost-effective maintenance of aging water transmission and distribution systems. The current research proposes a fast inverse transient analysis (ITA) ...
Pressure Surge Suppression Using a Metallic-Plastic-Metallic Pipe Configuration
Publisher: American Society of Civil Engineers
Abstract: Plastic pipes [e.g., polyvinyl chloride (PVC) or high density polyethylene (HDPE)] are commonly used to replace aging metallic pipe sections (e.g., cast iron) in water-distribution networks. However, our understanding ...
Condition Assessment of Water Pipelines Using a Modified Layer-Peeling Method
Publisher: American Society of Civil Engineers
Abstract: Pipe wall condition assessment is critical for targeted maintenance and failure prevention in water distribution systems. This paper proposes a novel approach for condition assessment of water pipelines by adapting the ...
Generalization and Analysis of Elastic Water Column Model for Hydraulic Transient Analysis of Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: AbstractThe elastic water column model (EWCM) has been enhanced through the integration of
dynamic electromechanical elements, such as pressure-reducing valves (PRVs) and pumps,
facilitating advanced transient analysis of ...
Anomaly Recognition in Water Pipe Systems Using a Characterization Framework and Persistent Hydraulic Transient Waves
Publisher: American Society of Civil Engineers
Abstract: AbstractAnomaly detection in pipe networks is critical for targeted maintenance within water
distribution systems. A paired impulse response function (termed paired-IRF) technique
to detect anomalies in pipe networks has ...
