RISAnalytical Solution of a Model of Contaminant Transport in the Advective Zone of a River
Publisher: American Society of Civil Engineers
Abstract: An analytical solution of a model of contaminant transport in the advective zone of rivers is presented and evaluated. An existing model that accounts for transport in the advective zone by dividing the channel into flowing ...
Disinfection By-Product Formation during Long-Term Water Storage in Alaska
Publisher: American Society of Civil Engineers
Abstract: In many areas of Northern and Western Alaska, small streams and shallow lakes serve as community raw water supplies. These water supplies freeze completely during winter. In order to supply drinking water during the 6–9 ...
Consequence-of-Failure Model for Risk-Based Asset Management of Wastewater Pipes Using AHP
Publisher: American Society of Civil Engineers
Abstract: Risk-based asset management focuses on prioritizing the most critical assets by evaluating their risk of failure. A typical way to determine the risk of failure is by assessing the asset’s likelihood of failure and its ...
Wind and Current Forcing Combine to Drive Strong Upwelling in the Agulhas Current
Publisher: American Meteorological Society
Abstract: trong upwelling events inshore of the Agulhas Current close to 33.5°S are investigated. These events are important to the exchange of shelf and slope waters, potentially enhancing primary productivity and advecting larvae ...
Capturing the Transport Variability of a Western Boundary Jet: Results from the Agulhas Current Time-Series Experiment (ACT)
Publisher: American Meteorological Society
Abstract: he volume transport of the Agulhas Current was measured over a 3-yr period by an array of seven current meter moorings and four current- and pressure-recording inverted echo sounders (CPIES) deployed at 34°S. CPIES extended ...
Designing Multi-axis Compliant Mechanisms With Lockable Decoupled Inputs: A Tip–Tilt Case Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research is about designing multi-degree-of-freedom (multi-DOF) compliant mechanisms with decoupled inputs that can be independently locked/unlocked using bistable switches to achieve different combinations of DOFs. ...
On the Relationship between North Atlantic Sea Surface Temperatures and U.S. Hurricane Landfall Risk
Publisher: American Meteorological Society
Abstract: In the recent literature, considerable attention has been paid to the relationship between climate signals and tropical cyclone activity. Much of the research has focused on Atlantic Ocean basin activity while less attention ...
Laser Scanning for Precise Ovalization Measurements: Standard Deviations and Smoothing Levels
Publisher: American Society of Civil Engineers
Abstract: Monitoring of measurements needs to be supported by a thorough knowledge of the achievable accuracy of the measurement equipment and the processing methodology. This study on ovalization monitoring with laser scanning in ...
Performance Evaluation of Pipe Break Machine Learning Models Using Datasets from Multiple Utilities
Publisher: ASCE
Abstract: Water pipeline infrastructures are critical for the delivery of lifeline services; however, these aging systems are experiencing increasing breakage rates. To assist utilities in identifying the most vulnerable assets, ...
Loss Breakdown in Axial Turbines: A New Method for Vortex Loss and Wake Detection From 3D RANS Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To enhance turbine efficiency, it is essential to mitigate the loss generated by irreversible phenomena taking place in turbine flows, including boundary layers, shock waves, vortices, and trailing edge wakes. A fast and ...
