Subsurface Utility Engineering and Megaprojects: Avoiding Underground Conflicts Helps Speed Project Delivery
Experienced project owners realize that utility conflicts can be risky and pose unexpected impacts on the cost and delivery of projects, especially in urban settings. To help overcome these impacts, Subsurface...
Toronto Takes Off
Travelers using Toronto's Pearson International Airport will soon be passing through a new, state-of-the-art terminal, the centerpiece of a 10-year airport redevelopment project....
Toronto's Tunnel Solution (Available in the Geoenvironmental Special Section only)
The Toronto Transit Commission (TTC), one of the largest public transportation systems in North America, carries more than 1,000,000 commuters a day. The TTC's tunnels had...
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....
Managing Great Lakes Water Levels: An International Partnership
During this century, the levels of two of the Great Lakes have been regulated; Lake Superior since 1921 and Lake Ontario since 1960. The regulation is directed by the International Joint...
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...

Lake Ontario Regulation Utilizing an Expert System Approach Constrained by Interest Satisfaction Relationships
Mass balance of historic and predicted total basin supplies to Lake Ontario forms the basis of an Expert Systems model constrained by interest satisfaction (IS) relationships. The IS Model...
Innovative Instrumentation for a Physical Model of River Ice Transport
Large physical models often require the use of innovative instrumentation and measurement techniques. Hydraulic models that attempt to simulate the effects of stationary ice covers put...
Interactive Models for the Regulation of Lake Ontario
Extensive studies are underway to improve the regulation of Lake Ontario. These studies not only involve the inclusion of factors and interest groups not previously considered, but also...
The Regulation of Lake Ontario During the Spring of 1993; a Period of Record Supplies
A wet summer in 1992 and record water supplies to Lake Ontario during early 1993 resulted in very high levels on the lake. Actions by the International St. Lawrence River Board of Control...
A Wind Driven Lake Circulation Finite Element Model for the Upper St. Marys River
The hydrodynamics of the Upper St. Marys River is simulated by a three dimensional steady state finite element model. The rigid lid and hydrostatic pressure assumptions are used in the...
Tuned Mass Dampers for Towers and Buildings
Tuned mass dampers (TMD's) are used to reduce the response of tall slender structures to resonant wind-induced oscillations. This paper reviews the authors' experience with the design...
Application of Shotcrete for Ground Support at Inco Mines
In 1989, shotcrete was first successfully introduced for ground support in production areas at Frood Mine. Until then the only successful application of shotcrete had been in major permanent...
Ecological Risk Assessment of Proposed Deep Geologic Disposal of High-Level Nuclear Waste in Canada
Using population dynamic models of moose and brook trout, and assuming topographic, hydrographic and other habitat features typical of the Canadian Shield in Ontario, we have estimated...
A Wave-Energy Dissipation Structure for Shore Protection and Beach Generation, Recovery, and Stabilization
WAVEBLOCK a steel reinforced concrete modularized structure designed to dissipate the energy of saline and freshwater waves is described. The modularized structure, which weighs upwards...
Meeting Information and Communication Needs in Regional Coastal Zone Management: Case Studies from the Great Lakes
Recent initiatives in regional coastal management within the Ontario Great Lakes basin, such as the preparation of Shoreline Management Plans by Ontario Conservation Authorities, background...
Hydrologic Regionalization Using a Homogeneity Test
A framework is presented for a regionalization method with a region of influence (ROI) approach. The methodology explicitly incorporates a homogeneity test in the process of selecting...
A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...
Effect of Agricultural Drainage on Water Quality in the Northeastern U.S. and Canada
Drainage has been used in the northeastern U.S. since colonial times. It has only been since the 1970s subsurface drains have been installed at a significant rate in Quebec. Drainage in...
