The aircraft-based eddy correlation technique was recently used to obtain regional observations of transfer processes of sensible and latent heat as well as carbon dioxide over wetlands...
Gas Transfer Measurements on an Ice-Covered River
Wasteload allocation for existing and proposed pulp mills in the Athabasca River Basin of northern Alberta, Canada, necessitated measurement of the atmospheric reaeration rate, K2,...
Carbon Dioxide Pressure in Surface Waters of Canadian Lakes
Direct measurements of the partial pressure (pCO2) of carbon dioxide were made in lakes of three study areas: ELA (the Experimental Lakes Area) and...
The Use of a Deep Shaft for the Waste Water Treatment Plant of Orgamol SA
The first version of a new deep aeration system has been built for Orgamol SA, a chemical plant in the Rhone valley, Switzerland. Construction, operation and oxygen transfer mode of the...
Problems with Rock Excavation Specification in Alberta
As a result of contract overruns and claims from classification, measurement, and payment for 'solid rock' excavation, Alberta Transportation and Utilities embarked...

Failure of Prestressed Concrete Embedded Cylinder Pipe
In 1964, the Ontario Provincial Government undertook to supply water to the City of London (current population 300,000). The supply source was from Lake Huron near Grand Bend, Ontario...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Iodine Transport Through the Soil-Plant-Atmosphere Continuum
The environmental assessment of the geological disposal of Canadian nuclear fuel waste involves transport modelling of radionuclides through the biosphere. Iodine-129 is a major fission...
Nuclear Fuel Waste Management in Canada?A Regulatory Perspective
This paper briefly identifies the process for development of a high-level radioactive waste repository in Canada, and the regulatory requirements and safety criteria which have been established...
A Numerical Study of Some Effects of Nuclear Fuel Waste Vault Construction and Closure on Evolution of Groundwater Flow Paths in the Geosphere
We have performed a series of three dimensional finite-element simulations on the sensitivity of the groundwater flow paths and travel times in a conceptual hydrogeological model with...
