Development of an Experimental Watershed for Testing Nonpoint Source Pollution from Urban Runoff
The U.S. Environmental Protection Agency (EPA) National Pollution Discharge Elimination System (NPDES) stormwater regulation program prohibits non-storm water discharges into entering...

Strengths and Weaknesses of Shallow Water Equations in Steep Open Channel Flow
The paper evaluates the strengths and weaknesses of shallow water equations in steep open channel flow. These equations, 1) St. Venant equations, 2) steep slope shallow water equations...

Numerical Experiments on Instability in Unsteady Flow Modeling
The problem of numerical instability in modeling unsteady open-channel flows is investigated using the technique of numerical experiments. The model is based on the one-dimensional de...

Investigation of an Anisotropic k-? Model
In this paper the eddy viscosity hypothesis is abandoned and explicit expressions of Reynolds stress are deduced directly from the transport equations. Anisotropic k and ? equations are...

Considerations in 2-D Modeling of Hydraulically Steep Flow
Simplifications in the equations used to describe shallow water flow lead to some difficulties in modeling supercritical flow. The hydrostatic assumption produces two significant differences...

Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...

Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...

Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...

Development of Long-Term Three-Dimensional Hydrodynamics in Long Island Sound for Use in Water Quality Modeling
The Blumberg-Mellor (1987) three-dimensional hydrodynamic model has been adapted by the National Oceanic and Atmospheric Administration's National Ocean Service (NOS) to provide hydrodynamic...

Modeling Ecological Impacts of Destratification
Artificial destratification has long been advocated as a means of improving water quality in lakes and reservoirs. The results have been varied with examples of both water quality improvement...

Model of an Upgrade
As further studies and more extensive computer models help engineers better understand the workings of wastewater treatment plant processes, those engineers are finding more efficient...

Analysis and Computation
This proceedings, Analysis and Computation consists of papers presented at the Eleventh Analysis and Computation Conference (formerly Electronic...

Computer-Integrated Construction
Computers have been used quite successfully as replacements for manual drafting, but to stop there seriously underuses the potential of computer aided design. By using the computer's...

Let's Go to the Videotape
Illustrating a design concept to educate and soften the resistance of community groups, environmentalists, government regulators and funding agencies is not a new idea. But the state of...

Hydraulics of Pipelines
The proceedings, Hydraulics of Pipelines, consists of papers presented at the International Conference on Hydraulics of Pipelines sponsored...
