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...

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...

Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...

Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD)
This publication, Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD), (ASCE 15-93), is applicable to buried concrete precast pipe intended...

Upgrading Dubai's Sewers
The sewerage system serving the city of Dubai in the United Arab Emirates, is plagued with odor and corrosion problems. System elements were deteriorating and failure rates were increasing....

Fundamentals and Advancements in Hydraulic Measurements and Experimentation
This proceedings, Fundamentals and Advancements in Hydraulic Measurements and Experimentation, contains papers presented at the Symposium held...

America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...

Offshore Rescue
Restoration of wastewater ocean outfalls can be difficult, dangerous and environmentally challenging. Two recent projects, however, serve as examples of innovative outfall rehab. The first...

Existing Sewer Evaluation and Rehabilitation
This manual, Existing Sewer Evaluation and Rehabilitation, Second Edition, provides general guidance and serves as a source of information...

Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...

Major Enhancements to TRANSYT-7F
TRANSYT-7F is one of the most powerfull computer programs fir traffic signal timing and traffic flow analysis. This paper describes some of the significant improvements over earlier versions...

Fast Foundation for Soft Clay
This article describes the detailed foundation work and high-capacity piling design for a flue gas desulfurization (FGD) retrofit system for the Lambton Generation Station in Ontario,...

Wind Tunnel Testing for the Great Belt East Suspension Bridge
This paper provides an overview of model tests conducted to study and predict the aerodynamic behavior of the proposed streamlined box-girder suspension bridge for the Great Belt Link....

Bridge Aerodynamics and Response Control?Recent Research and Developments in Japan
Bridge aerodynamics and its response control with emphasis on the recent R/D in Japan are reviewed. Aerodynamic countermeasures based on the vibration mechanisms as well as mechanical...

On the Numerical Simulation of Wind Loads on Structures
A new methodology for numerical simulation of 3-dimensional turbulent flow based on the use of a Galilean frame and the finite point method is presented. The pressure field of the solutions...

Fluid Viscous Damper for Improving the Earthquake Resistance of Buildings
Experimental results are presented which demonstrate that the use of fluid dampers as add-on devices in moment resisting frames substantially increases damping and reduces seismic story...

Ductility Analysis of Overload and Settlement
The concept of sufficient ductility to avoid premature or brittle failures is gaining wide acceptance in structural engineering and is an important aspect in mitigating the consequences...

The Innovative Concept of Semi-rigid Composite Beam
This paper discusses invention and development of a new type of composite beam called 'Semi-rigid Composite Beam.' This new type of beam is expected to behave better than presently used...
