The Ontario Ministry of Energy initiated a project to develop an analysis program based upon metric measures and Canadian costs. The Ministry of Energy of the Province of Ontario has been...

Studies of Fish Protection Methods at Hydroelectric Plants
Five largely untested but economical fish-protection systems were tested at sites throughout North America. The process of selecting laboratory and field test sites was completed at the...

Environmental Appraisal of Small Hydro Projects in Ontario
Despite a large interest from the developing community and the aid of Ontario's Small Hydro Encouragement Program (Ministry of Energy 1986) which is administrated by the Ontario...

Operational Flexibility?A Precious Commodity
This discussion is about Operational Flexibility, as it applies to the generating resources of a large electricity system. The author discusses the situation at Ontario Hydro, operationally...

Trends and Emerging Issues: A Longitudinal Study of Government Agencies' Perceptions of Great Lakes Water Resources and Related Issues
The perceptions of government agencies with jurisdiction over Great Lakes' shoreline has changed over time with respect to important issues related to water quality and a...

Quality Assurance Monitoring of a Large Clay Liner
The Keele Valley Landfill at Maple, Ontario, consists of a 99 ha (245 acre) facility to serve the Metropolitan Toronto area. The landfill is located in a former sand and gravel pit, with...

Multiple Presence Reduction Factors for Bridges
This paper reviews the multiple presence reduction factors specified in the AASHTO and Ontario codes, and provides a method by which these factors can be established in relation to volume...

Waterpower in Ontario
Ontario Hydro, a public utility, is responsible for the generation and transmission of almost all the electricity used in Ontario. In 1984 approximately 30% of Ontario's electricity...

Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...

Safety Impacts of Installing Pedestrian Crosswalks
At-grade pedestrian crossovers (PXO's) have been installed at about 700 locations in Metropolitan Toronto to assist pedestrians in crossing busy streets at minimal delay to...

Remote Sensing to Assess Effects of Hydroelectric Development
Planning for hydroelectric development of rivers in the province of Ontario, Canada requires extensive environmental evaluation and assessment. To test the feasibility of using digital...

Dredged Material Disposal in the Lower Great Lakes
The Buffalo District Corps of Engineers is responsible for dredging the harbors in Lakes Erie and Ontario. Approximately 2,000,000 cubic yards (1,529,000 cubic meters) of material are...

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...

Design and Testing of a 400 Ft Span Plate Girder Bridge
