A plume rise model is derived from the equations of turbulent motion, retaining the turbulent flux terms. The solutions are similar to those proposed earlier by Csanady but containing an exponential decay term. The model finds particular value in predicting a leveled-of£ plume trajectory in...

Lutz, A., Hendzel, M.

Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton...

Green, J. E.

The afforestation program in the Athabasca Oil Sands area has been only moderately successful, because of the high mortality of the planted seedlings--much of which Is believed to be the result of high levels of small mammal damage. The objectives of the present study were: (1) to determine the...

Nyborg, M., Takyi, S.K., Rowell, M.H., McGill, W.B.

One of the major environmental problems which arises with surface mining of the oil sands in the Fort McMurray-Fort MacKay area of Alberta is the permanent loss of the natural vegetation and the drastic change in the soils that supported it. It has been estimated that with a production target of...

Bliss, L. C. (Ed.)

This project on the \"Long Term Prediction of Vegetation Performance On Mined Sands\" (V.E.6.1) was undertaken to provide management with answers on the predictive ability to maintain different kinds of vegetation on raw sands. The research was designed as an integrated, multi-disciplinary...

Djurfors, S.

The equations expressing the conservation of mass, vertical momentum and energy are solved analytically for the rise of buoyant plumes in calm atmospheric conditions. The separate and joint effects of entrainment and drag on plume behavior are discussed.

This study, initiated by Syncrude's Environmental Affairs Division, was undertaken: • to specify the objectives and structure of a socio-economic impact assessment program; • to determine information required to satisfy existing and anticipated requirements of government agencies and...

Exploitation of the bituminous sands may elevate heavy metal levels in the sediments of drainage systems of the AOSERP area via waterborne or airborne emissions. One hundred and six dredged sediments and twenty-four sediment cores were collected from the Athabasca River system from just above...

Selner, J., Thomson, R.

During 1976, a variety of methods and materials were used in the search for afforestation practices that will assist in the establishment of a self sustaining vegetation cover compatible with land use objectives for the Alberta oil sands area. The project study area is located on the Great,...

This monograph describes the vegetation that existed in August 1977 on the western half of Syncrude's Lease 17 near Fort McMurray, Alberta. Eight vegetation types were identified and are mapped in this monograph at a scale of 1:24,000. Black Spruce - Labrador Tea was the dominant vegetation...
