RISGlobal Predictive Real-Time Control of Sewers Allowing Surcharged Flows
Publisher: American Society of Civil Engineers
Abstract: A global predictive real-time control strategy minimizing overflow volumes from combined sewers during rainfalls is presented. For an optimal use of controlled sewer transport and storage capacities, the proposed strategy ...
Performance Estimation of a Remote Field Eddy Current Method for the Inspection of Water Distribution Pipes
Publisher: American Society of Civil Engineers
Abstract: Remote Field Eddy Current (RFEC) technology allows the in situ inspection of metallic water distribution pipes. RFEC tools provide the location and magnitude of corrosion defects on the inspected pipes. The capacity of an ...
Modeling Water Pipe Breaks—Three Case Studies
Publisher: American Society of Civil Engineers
Abstract: Municipal water infrastructure systems are in poor condition and are deteriorating rapidly. A general diagnosis of the actual structural state of these systems is needed, as are tools to assess their rate of deterioration. ...
General Model for Water-Distribution Pipe Breaks: Development, Methodology, and Application to a Small City in Quebec, Canada
Publisher: American Society of Civil Engineers
Abstract: To model water-pipe breaks a generalization is proposed of an approach where a Weibull exponential model was used for simulation. In this study, a generalization of this approach was performed by developing a general model ...
Multiobjective Approach for Pipe Replacement Based on Bayesian Inference of Break Model Parameters
Publisher: American Society of Civil Engineers
Abstract: A planning strategy is presented that aims at establishing the optimal replacement schedule for a water distribution network. Two performance indicators are defined. The first accounts for structural state (total cost ...
Distributed Watershed Model Compatible with Remote Sensing and GIS Data. I: Description of Model
Publisher: American Society of Civil Engineers
Abstract: A distributed hydrological model compatible with remote sensing and GIS has been developed over the past years. Run on microcomputers with a user-friendly interface, the HYDROTEL model can be applied to a wide range of ...
Distributed Watershed Model Compatible with Remote Sensing and GIS Data. II: Application to Chaudière Watershed
Publisher: American Society of Civil Engineers
Abstract: In an accompanying paper, the HYDROTEL model, a distributed hydrological model compatible with remote sensing and GIS, has been presented. Run on microcomputers with a user-friendly interface, the HYDROTEL model can be ...
Planning Unidirectional Flushing Operations as a Response to Drinking Water Distribution System Contamination
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the issue of contaminated water evacuation as part of the response process in cases of intentional or accidental contamination of drinking water distribution systems (DWDSs). Following a previous study ...
Heuristic Approach for Operational Response to Drinking Water Contamination
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a simple topological approach to systematize the isolation of contaminated areas within the pressure zones of drinking water distribution systems (DWDSs). Assuming optimal location of contaminant ...
