Publisher: American Society of Civil Engineers
Adaptive Time Stepping–Operator Splitting Strategy to Couple Implicit Numerical Hydrodynamic and Water Quality Codes
Publisher: American Society of Civil Engineers
Abstract: Hydrodynamic and water quality codes have been frequently linked. These have typically been linked with both the hydrodynamic and water quality models using similar explicit time steps, but for long-term simulations implicit ...
Conceptual Model of Salinity Intrusion by Tidal Trapping
Publisher: American Society of Civil Engineers
Abstract: Shallow bays along the fringe of an estuarine channel impact salinity distribution. The primary mechanism of impact has been termed “tidal trapping,” and is a result of the phase difference between the filling and emptying ...
Discrete Fluxes and Mass Balance in Finite Elements
Publisher: American Society of Civil Engineers
Abstract: Significant mass balance “errors” have been reported with finite-element techniques, leading to sweeping statements that “Finite elements do not conserve mass locally.” These reports of mass balance “error” emerge when ...
Simulating Barge Drawdown and Currents in Channel and Backwater Areas
Publisher: American Society of Civil Engineers
Abstract: The act of a barge train navigating along a waterway produces waves and alters the river's currents. The drawdown wave causes flow exchange with the backwaters and side channels. The return currents in narrow waterways can ...
Finite-Element Model for High-Velocity Channels
Publisher: American Society of Civil Engineers
Abstract: Numerical modelers of high-velocity channels are faced with supercritical transitions and the difficulty in capturing discontinuities in the flow field, known as hydraulic jumps. The implied smoothness of a numerical scheme ...
Refinement Indicator for Mesh Adaption in Shallow-Water Modeling
Publisher: American Society of Civil Engineers
Abstract: Automatic mesh refinement can create suitable resolution for a hydrodynamic simulation in a computationally efficient manner. Development of an automatic adaptive procedure will rely on estimating and/or controlling ...
Two-Dimensional Flow Model for Trapezoidal High-Velocity Channels
Publisher: American Society of Civil Engineers
Abstract: A two-dimensional numerical flow model for trapezoidal high-velocity channels is developed. The model is designed specifically for simulation of flow in channels having sloping sidewalls in which the depth is an unknown ...
Efficient, Robust Design Tool for Open-Channel Flow
Publisher: American Society of Civil Engineers
Abstract: The use of computational fluid dynamics to simulate physical phenomenon, such as flow through open channels, has become more prolific as computational resources and numerical algorithms have improved. With current algorithms, ...
