Dans le cadre d'un projet de recherche en cours portant sur l'évaluation de la vulnérabilité municipale aux catastrophes naturelles (Boivin 1990), un examen des dommages du séisme du 25 novembre 1988 a été mené afin de mieux documenter l'analyse du risque séismique au Québec. À partir de sources variées de rapports de dommages mais, plus spécifiquement, par l'étude des demandes liées au programme de dédommagement mis sur pied par le gouvernement du Québec, une analyse et une cartographie des dommages rapportés est fournie. Les résultats montrent que la majorité des dommages sont concentrés près de l'épicentre dans les régions du Saguenay/Lac Saint-Jean et de Québec. Les dégats répertoriés concernent principalement les ouvertures (portes et (enê tres) avec 11%, les murs intérieurs ou extérieurs (29%), l'apparition de fissures (72%), les fondations (44%) et les cheminées (29%). Au total, 1521 cas de dommages ont été rapportés et analysés dans ce projet de recherche. 相似文献

The results of a recently completed inventory of Australian estuaries and enclosed marine waters are summarised The inventory was compiled to gain a national perspective on the ecological status of estuaries and to ufentify research and management priorities The database shows that most estuaries in northern and western Australia have been relatively unaffected by human activity. In contrast estuaries in eastern and southern Australia generally have lower water quality and greater catchment clearance and a high percentage face real threats to their conservation values The estuaries in N.S. W. and VicroM have the most ertensive literature available. The results suggest that, given clearly defined management priorities, many representative and important features can still be adequatety conserved in a national system of estuarine reserves Subject areas where more research is needed include individual catchment characteristics, water quality, fihehs and conservation values and more detailed mapping. especially for seagrass beds and intertidal mud banks. 相似文献

Summary. The development of academic géography in Canada was somewhat similar to that in the United States. At the turn of the century géography was probably stronger in the schools in most provinces than it was in most states, but in both countries it seemed to be mainly an uninspired collection of facts about particular places in the world. There was no leadership from Canadian universities to improve the quality of géography nor to change its content or philosophy. As in the United States, but on a smaller scale, géography was known in a few Canadian universities prior to World War I. Its real beginnings, however, were in the latter part of the 1930s. 相似文献

Summary. This paper considers the apparent absence of house or settlement platforms in Iron Age lowland England. It demands that lowland sites be interpreted using criteria derived from suitable (lowland) contexts. The dangers of using upland-derived explanatory models are illustrated with selected examples. The Cat's Water subsite, Fengate, Peterborough provides examples of probable house-platforms, protected from plough-damage by alluvium; these, in turn, are used to provide criteria to recognise similar features on poorly preserved sites. Comparisons are drawn with recently excavated sites in the Netherlands. The paper concludes with some general observations on the nature of once-wet sites and the dangers inherent in their interpretation. 相似文献
