Effects of Spillway Operation on Cavitation Damage to Hugh Keenleyside Dam Spillway
The Hugh Keenleyside Dam (also known as Arrow Dam) is located on the Columbia River, at the outlet of Lower Arrow Lake, 53 km north of the Canada - U.S.A. border. The project has been...
Toronto Skydome Retractable Roof Stadium?The Roof Concept and Design
The Toronto SkyDome is a first of its kind sports stadium with a retractable roof which results in, essentially, a fully open air stadium with the roof fully retracted. This unique roof,...
The Use of Penetrating Sealers on Concrete Bridge Decks
Acceptance criteria for Penetrating sealers is shown. Penetrating sealers can be used as cost effective preventive maintenance for bridge deck concrete in northern climates. Factors affecting...
Wind Effects on Loose-Laid Cladding Systems
Modern roofing systems for flat roofs frequently make use of rigid insulation boards, gravel and concrete pavers that are loose-laid on top of the waterproof membrane. The authors have...
Rock Excavations in Downtown Toronto
The geology of Toronto area is somewhat complex due to the series of advances and retreats of the glaciers. The overburden deposits consist of materials laid down during the Wisconsinan...
Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...
Biological Phosphorus Removal Using a Fixed and Suspended Growth Combination: A First Year Appraisal
As an alternative to the activated sludge process for biological phosphorus removal, this paper discusses an alternative which avoids high costs of air supply and large suspended growth...
Peat Filtration for Oil Removal
An investigation was carried out to assess the potential of horticultural peat produced in Saskatchewan as a filter medium in treating five oil-in-water emulsions (standard mineral oil,...
Aerobic Thermophilic Digestion or Liquid Composting of Municipal Sludges
A study funded by Supply and Services Canada through the Wastewater Technology Center of Environment Canada, and the Province of British Columbia is being undertaken over a two year period...
Simulation of Oxygen Dynamics in the Vadose Zone
A microcomputer model VIP (Vadose Zone Interactive Processes) was developed as an extension of the RITZ model to provide a mathematical description of land treatment systems for the disposal...
Sensitivity of Non-Point Source Models to Net Rainfall
A sensitivity analysis of the ANSWERS model was conducted to explore the possible impact on model outputs of discretizing rainfall input data into short time increments of various durations....
Behavior of Total Zinc in the Similkameen River
Multiple linear regression analysis was used to: develop equations that summarize the relationship between total zinc and a set of water quality characteristics measured in the Similkameen...
Prediction of Overland Phosphorus Transport Using a Phosphorus Enrichment Ratio
The Guelph model to evaluate the effects of Agricultural Management Systems on Erosion, Sedimentation, and Phosphorus yield (GAMESP) of Rousseau et al. was used to calibrate the phosphorus...
Diplomacy and International Environment Issues
