Determining the Internal Wall Condition of a Water Pipeline in the Field Using an Inverse Transient
Publisher: American Society of Civil Engineers
Abstract: The application of inverse transient analysis (ITA) to estimate the location and magnitude of lost lining and internal corrosion of metal pipelines is demonstrated for a field pipeline. The method uses a transient model ...
Drought Analysis Using Trivariate Copulas Conditional on Climatic States
Publisher: American Society of Civil Engineers
Abstract: Droughts are an inevitable consequence of meteorological variability, and the design of water resource infrastructure and management strategies to mitigate their effects requires assessment of the risk. Crucial characteristics ...
Parameter Identification in Pipeline Networks: Transient-Based Expectation-Maximization Approach for Systems Containing Unknown Boundary Conditions
Publisher: American Society of Civil Engineers
Abstract: The simulation of hydraulic transients within fluid line networks is important for many applications (for example, water hammer analysis within distribution networks). However, in many instances, modeling efforts are impeded ...
Closure to “Systematic Evaluation of One-Dimensional Unsteady Friction Models in Simple Pipelines” by J. P. Vítkovský, A. Bergant, A. R. Simpson, and M. F. Lambert
Publisher: American Society of Civil Engineers
Field Measurements of Mean Velocity Characteristics of a Large-Diameter Swirling Jet
Publisher: American Society of Civil Engineers
Abstract: Full-scale field acoustic Doppler velocimeter measurements of the radial, axial, and tangential flow components were undertaken in a large-diameter turbulent swirling jet generated by a raft-mounted axial flow-mixing ...
Calibrating the Water-Hammer Response of a Field Pipe Network by Using a Mechanical Damping Model
Publisher: American Society of Civil Engineers
Abstract: Hydraulic transient field tests have been conducted in a water distribution network. Existing transient models are applied to model the measured responses, but poor matches are obtained apart from the estimation of the ...
Optimal Pipe Network Sensor Layout Design for Hydraulic Transient Event Detection and Localization
Publisher: ASCE
Abstract: Excessive hydraulic transients in a water distribution system (WDS) can instantaneously damage equipment and infrastructure, while long-term pressure oscillations can contribute to pipe structural deterioration and eventually ...
