Intelligent Transportation Education
The comprehensive traffic surveillance study for the New York State Thruway Authority (NYSTA) began in late September 1993. The project involved the study of available traffic management...

Effects of Approach Flow Conditions on Pump Sump Design
An important obstacle to the development of a generalized sump design is the variability of flow conditions in approach areas. The geometry and alignment of the areas immediately upstream...

Feasibility of Modeling Phosphorus Dynamics in Stormwater Wetlands
This research, underway at the University of Guelphs School of Engineering, studies the feasibility of modeling phosphorus assimilative capacity by stormwater wetlands in cold climates....

Design and Implementation of a Multi-Faceted Site Remediation
This technical paper presents a case history of the design, construction, and start-up of a multi-faceted site remediation system. The case history includes a description of the site background,...

Comparative Simulation of Oil Weathering
Oil spills in the aquatic environment, an unfortunately more and more common occurrence, cause contamination effects which negatively impact water quality, health of ecosystems and water...

Comparison of Methods for Sizing Secondary Treatment Filters for Wastewater
The trickling filter process in which a bacterial biomass is allowed to grow attached to a filter medium of rock or plastic is effectively used for removal of organic materials in domestic...

A Surface Collection Design Approach on the Lower Columbia River
Surface collection and bypass of downstream migrating juvenile salmon has the potential to help improve the survival of the Columbia River salmon population. However, surface passage on...

Impact of Sedimentation Caused by Runoff
As water is pumped into a reservoir, sedimentation caused by runoff can be an important factor in the reservoir's storage capacity. This report discusses various studies conducted...

Establishing the Relative Process Risks for Chlorination and Ozonation - A Case Study Illustrates the Need to Evaluate the Process Hazard Implications of a Change in Drinking Water Disinfection Process due to D/DBP Regulations
Many drinking water suppliers in this country may choose to modify their primary disinfection process to meet stricter water quality standards under the United States Environmental Protection...

Development and Application of a Dual Drainage Model for the Wethersfield Area of the City of Hartford, Connecticut
A combined system, with overflows, existed in the City of Hartford, Connecticut. Although effective in the context of design standards prevailing at the time of its original design, the...

Pipe Network Analysis and Design in Developing Regions. Case Study: Novokuznetsk, Siberia
Pipe network analysis, design and optimization in developing countries poses some unique problems, yet, is of paramount importance. Under these conditions, there is frequently only sparse...

Optimization of Soil Vapor Extraction System Design
Soil vapor extraction is a cost-effective technique for the removal of volatile organic compounds (VOCs) immobilized in the unsaturated zone. The design of a soil vapor extraction system...

Costs of Treatment for Wastewater Reclamation and Disposal: A Preliminary Assessment
Our objective is to estimate the marginal costs of different degrees of water reclamation treatment (primary, secondary, and tertiary), using the Los Angeles County Sanitation District...

A Process Unit Based Approach to Media-Integrated Waste Minimization: A Paint Manufacturing Case Study
Research conducted at the School of Engineering, University of Guelph, has developed a media-integrated waste minimization plan for a major Ontario paint and coatings manufacturer. The...

Application of Regime Theory in Practice: A Case Study
Alluvial channels are known to adjust their slope, width, depth and velocity to achieve stable conditions given a supply of water and sediment. Scientific investigations of stable channels...

Identifying Trends from Streamflow Records?A Case Study
Historical streaniflow records for the Ruby River, in southwestern Montana were analyzed for trends and for changes in the precipitation-runoff relationship. Trends were first identified...

Uncertainty in Comparative Analysis with Continuous Nonpoint Source Pollution Models
There have been few attempts to quantify the impact of parameter uncertainty in comparative analysis with continuous nonpoint source pollution models. This paper presents the results of...

The Last Two Extreme Floods in Germany?Analyses and Consequences
The last two extreme floods in Germany occurred in December 1993/January 1994 and January 1995 within the River Rhine basin with both floods having different causes. In a comparison study,...

A Comparative Study of the Transformed Methods for Solving Richards' Equation
The Richards' equation represents the movement of water in both saturated and unsaturated porous medium. The numerical solution to this equation is difficult because the algebraic...

Inundation Studies in Case of Failure of King Talal Dam
In this paper a brief description of the studies is presented and the computed results are summarized. During running the program, several difficulties were encountered. These problems...
