Session: Reliability and Risk II

ABSTRACT: Steep creek hazards such as debris flows and debris floods pose considerable risks to mountain communities and infrastructure. In Europe and Japan, centuries of experience in steep creek hazard mitigation have produced substantial practical design knowledge. By comparison, Canadian professionals have limited experience with engineered debris-flow and debris-flood risk management. To close the knowledge gap, we present a design approach that aims to improve the state of practice in Canada, drawing from local and international experience.

RÉSUMÉ: Les aléas liés aux torrents à forte pente tels que les laves torrentielles ou écoulements hyperconcentrés posent un risque considérable pour les communautés et infrastructures de montagne. La gestion de ces aléas en Europe et au Japon remonte à plusieurs siècles et a permis la conception et mise en pratique d™un nombre important de solutions. En comparaison, les professionnels canadiens ont une expérience limitée de la gestion des risques liés aux laves torrentielles et écoulements hyperconcentrés. Afin de combler ces lacunes, nous présentons une approche de conception qui vise à améliorer l'état actuel de la pratique au Canada, en s'appuyant sur l'expérience locale et internationale.
