Thermal Plume Model for Demonstrating Compliance
A numerical model that simulates the discharge of heated water from a multiport line diffuser to a thermally stratified, flowing environment was developed. The model solves the conservation...
Modeling Aquifer Sensitivity and Leachate Controls
This paper investigates the transport of waste leachate from a leaky containment facility using the computer model of Two-Dimensional Solute Transport and Dispersion in Ground Water developed...
Seasonal Hydrothermal Operating Plans
An interactive computer model is presented which provides graphical displays of alternative generation patterns for an integrated hydroelectric and thermal system. The method for analyzing...
Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharge. A simple analytical procedure is presented for estimating the loss in turbine efficiency...
Biological Evaluation of Angled Screen Test Facility
The paper presents comparisons of model and prototype measurements as a means for evaluating the ability of a physical model to reproduce a geometrically complex prototype thermal intake...
Biofouling Control of Water Intake Structures
Biofouling of water intakes can affect condenser performance and availability. This paper discusses four biofouling control technologies: thermal backwash, antifouling coatings, chlorination,...
Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...
Incorporating 3-D Effects into a 2-D Model
Some three-dimensional (3-D) effects may be incorporated into vertically averaged two-dimensional models. This is demonstrated with a case study where the effects of a complex system of...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Ground-water Modeling on Small Computers: Past, Present, and Future
The paper reports on research that concerns the possible development of numerical models being able to simulate practical cases of Oil Spill Migration (OSPIM) in soils. Such models can...
Cable Propelled People-Movers?An Idea Whose Time Has Come Again
Cable-propelled transportation systems have been in use throughout the world for more than a century. Today, a completely automated cable-propelled transit system has been developed through...
Hazardous Waste Cleanup: The Preliminaries
Court-ordered negotiations rather than a trial took five years but led to a flexible plan for cleaning up an inactive hazardous waste disposal site in Niagara Falls, N.Y. Contamination...
Insulative Lightweight Concrete for Building Walls
Research is currently being conducted to develop a portland cement concrete for use in low-rise building walls that will combine the structural, thermal insulating, and heat storage capacity...
Analysis of Cracking of I79 Bridge at Neville Island
A large crack was discovered to form in a girder of the I-79 Glenfield Bridge over the back channel of the Ohio River near Pittsburgh on January 28, 1977. A section of the girder containing...
Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
Environmental Engineering
The purpose of the annual Conference on environmental engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of environmental...
Thermal Design Considerations in Frozen Ground Engineering
Prepared by the Technical Council on Cold Regions Engineering of ASCE. The design of engineering projects in frozen ground requires thermal design considerations...
Assessing the Effects of Water Contamination
The threats to potable water are examined. An assessment of human ill effects of contaminated water requires a knowledge of the quality of water throughout the world and a corresponding...
How Should We Dispose Hazardous Wastes?
Our inability to successfully dispose hazardous wastes has led to extensive land, groundwater and surface water pollution. The question is not whether we have the technology to do the...
Superfund Cleanup Sites
Cleanups of four Superfund hazardous waste sites are described, two in Pennsylvania, one in Tacoma, Wash., and one in Globe, Arizona. The key chemical wastes were polychlorinated bipheynls,...
