RISInfluence of Ground Conditions on Intrusion Flows through Apertures in Distribution Pipes
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new, tractable analytical expression to describe the intrusion of fluids into buried pipes under steady-state conditions. The expression is validated with results from novel experiments. The derivation ...
Modeling and Field Work to Investigate the Relationship between Age and Quality of Tap Water
Publisher: American Society of Civil Engineers
Abstract: It has been widely theorized that water age may be a useful indicator of the quality of water within drinking water distribution networks. However, there is limited evidence of model simulation results being related to ...
Field Studies and Modeling Exploring Mean and Maximum Water Age Association to Water Quality in a Drinking Water Distribution Network
Publisher: American Society of Civil Engineers
Abstract: This paper presents the findings of an investigation into predicted/modeled water age and the associated quality characteristics within a UK drinking water distribution network to determine if there is a discernable link. ...
Experimental Study Exploring the Interaction of Structural and Leakage Dynamics
Publisher: American Society of Civil Engineers
Abstract: Strategies for managing leakage from water distribution systems require the ability to effectively evaluate such real losses through the understanding of the behavior of individual leaks, including their response to changes ...
Experimental Quantification of Contaminant Ingress into a Buried Leaking Pipe during Transient Events
Publisher: American Society of Civil Engineers
Abstract: It has been hypothesized that negative pressures caused by transients within water distribution systems may result in ingress of contaminated groundwater through leaks and hence pose a risk to public health. This paper ...
Experimental Quantification of Intrusion Volumes due to Transients in Drinking Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: Currently it is not possible to fully assess the risks to human health and wellbeing from contaminant intrusion into drinking water distribution systems due to lack of understanding and accurate estimation of intrusion ...
Experimental Quantification of Contaminant Ingress into a Buried Leaking Pipe during Transient Events
Publisher: American Society of Civil Engineers
Abstract: It has been hypothesized that negative pressures caused by transients within water distribution systems may result in ingress of contaminated groundwater through leaks and hence pose a risk to public health. This paper ...
Integrated Sensor Placement and Leak Localization Using Geospatial Genetic Algorithms
Publisher: ASCE
Abstract: There is an urgent need to reduce water loss from drinking water distribution systems. A novel framework that integrates the placement of multiple pressure sensors and localization using geospatial techniques is developed ...
Improved Representation of Water Age in Distribution Networks to Inform Water Quality
Publisher: American Society of Civil Engineers
Abstract: Mathematical simulation models that are used to provide information about the age of water in potable water distribution networks usually represent the age of water as the flow weighted average age value of the merged flows ...
Cloud-Based Artificial Intelligence Analytics to Assess Combined Sewer Overflow Performance
Publisher: ASCE
Abstract: Discharges from combined sewer overflows (CSO) are unacceptable, particularly when they are not linked to wet weather. This paper presents an evaluation of an online artificial-intelligence-based analytics system to give ...
