Hydro-Que´bec wants to divert the Kipawa River in northwest Que´bec from its natural streambed. While the first time visitor is likely to emphatically proclaim the Kipawa River as the most beautiful, most serene place they have ever encountered, hydro consultants and engineers, disconnected from the attractiveness of that place, are making cost/benefit recommendations that marginalize the inherent value of a free-flowing Kipawa. This paper will discuss the following points: (1) The Kipawa River has its own inherent value, which is related to the cost of simulating threatened white-water habitats in general. (2) The costs of recreating white-water habitats are more understandable through the study of man-made white-water venues. (3) The cost to recreate or simulate a threatened white-water habitat should be factored into the cost of the hydro-project feasibility. The Kipawa River's own inherent value should be factored into the cost of the Tabaret Diversion Project. (4) Methods of gaining community acceptance should be public and open: independent third-party arbitartion is recommended. Use of monetary incentives to encourage public acceptance is unethical, immoral and unjustly biased against the survival of white-water habitats. (5) Recreational use of white-water habitats, like the Kipawa River are increasingly important engines of economic growth in Canada and around the world. [Copyright &y& Elsevier]

Investigates the mechanism of erosion and the factors influencing erosion rates of clay banks of the Saint Lawrence River along the Montréal to Lac Saint Pierre n Quebec. Literature review; Details on the experiments; Results of the study; Conclusions.

Discriminant analysis of 80 samples from the Western Carbonate Platform Facies and the Eastern Transitional Carbonate–Siliciclastic Platform Facies of the Gun River Formation (Lower Silurian) on Anticosti Island, Quebec, indicates the degree to which different conodont communities were related to particular lithofacies. The statistical analysis reveals that during most of the Gun River Formation deposition, the conodont distributional pattern of the Western Carbonate Platform Facies and the Eastern Transitional Carbonate–Siliciclastic Platform Facies of the formation remained stable, and that the boundary of the two facies oscillated eastward and westward. The analysis indicates quantitatively that Icriodella deflecta had a nearshore environmental preference, whereas Rexroadus kentuckyensis tended to reside in offshore environments. These two species play the most important role in differentiating conodont communities and determining the relationship between conodont communities and lithofacies among all of the 22 species known from the Gun River Formation.Une analyse discriminante de 80 échantillons du faciès occidental de la plate-forme carbonatée et du faciès oriental de la plate-forme de transition carbonate–siliclastique de la Formation de Gun River (Silurien inférieur) sur l'île d'Anticosti, au Québec, indique le degré de relation entre les diverses communautés de conodontes et des lithofaciès particuliers. L'analyse statistique révèle que, lors de la déposition de la plus grande part de la Formation de Gun River, le patron de distribution des conodontes du faciès occidental de la plate-forme carbonatée et celui du faciès oriental de la plate-forme de transition carbonate–siliclastique de la formation sont demeurés stables et que la limite entre les deux faciès oscillait vers l'est et vers l'ouest. Les résultats quantitatifs de l'analyse indiquent que Icriodella deflecta préférait les environnements littoraux alors que Rexroadus kentuckyensis avait plus tendance à rester dans des environnements au large. Ces deux espèces sont les plus significatives pour différencier les communautés de conodontes et déterminer la relation entre les communautés de conodontes et les lithofaciès parmi toutes les 22 espèces connues dans la Formation de Gun River.[Traduit par la Rédaction] [ABSTRACT FROM AUTHOR]
