RISCalibrating Pipe Wall Demand Coefficient for Chlorine Decay in Water Distribution System
Publisher: American Society of Civil Engineers
Abstract: Methodology and algorithm to calibrate pipe wall demand coefficients for chlorine decay using an input-output model framework are developed and applied. An input-output model of water quality in water distribution systems ...
Random Walk Particle Tracking to Model Dispersion in Steady Laminar and Turbulent Pipe Flow
Publisher: American Society of Civil Engineers
Abstract: To accurately model a two-dimensional solute transport in drinking water pipes and determine the effective dispersion coefficients for one-dimensional water quality models of water distribution systems, a random walk ...
Actual Working Performance Assessment of Super-High Arch Dams
Publisher: American Society of Civil Engineers
Abstract: China is addressing the significant challenge posed by the construction of several 300-m-high arch dams for the effective use of hydropower resources. Limited experience has been gained globally in the construction of ...
Particle Backtracking Algorithm for Water Distribution System Analysis
Publisher: American Society of Civil Engineers
Abstract: A novel input-output model of water quality in water distribution systems is presented as a particle (water parcel) backtracking algorithm (PBA). The PBA is a simpler and more efficient version of that described by Zierolf ...

Real-Time Identification of Possible Contamination Sources Using Network Backtracking Methods
Publisher: American Society of Civil Engineers
Abstract: In case of contamination intrusion in water distribution systems, water quality sensor data can be used to determine the location and time of the contamination source. One approach to contamination source identification ...
Lagrangian Method to Model Advection-Dispersion-Reaction Transport in Drinking Water Pipe Networks
Publisher: ASCE
Abstract: A Lagrangian method to simulate the advection, dispersion, and reaction of a single chemical, biological, or physical constituent within drinking water pipe networks is presented. This Lagrangian approach removes the need ...
Framework for Modeling Lead in Premise Plumbing Systems Using EPANET
Publisher: ASCE
Abstract: The lead contamination of drinking water in homes and buildings remains an important public health concern. In order to assess strategies to measure and reduce exposure to lead from drinking water, models are needed that ...
Lateral Behavior of Masonry-Infilled Wood Frames with Wood Diagonal Bracings of Different Forms
Publisher: ASCE
Abstract: Masonry-infilled wood frame walls are widely used in vernacular buildings all over the world. Based on traditional European wood frame walls, this paper proposes wood bracing as reinforcement for traditional Chinese ...
