Session: Geohazard Monitoring Tools

ABSTRACT: Geohazard monitoring for networks of linear infrastructure have traditionally involved time-intensive and intrusive monitoring methods using permanently installed instruments. These traditional methods often require expensive mobilization and site access for larger vehicles compared to more modern methods. Combining traditional instrumentation and modern monitoring technologies allows for greater understanding of hazards and development of risk reduction strategies. These technologies provide an economically efficient means of improving monitoring processes, often minimizing the need for costly permanent instrumentation installation. This paper presents the application of light detection and ranging (LiDAR) and differential global positioning systems (GPS) to improve upon sparse historical records and enhance the understanding of the development, progression, and mechanisms of landslides. A number of issues involving their use in slow-moving, vegetated landslides is also discussed. As a case study, we use a slow-moving vegetated landslide located in Southern Alberta called the Chin Coulee landslide.

RÉSUMÉ: La surveillance des géorisques pour les réseaux surveillance chronophages utilisant des instruments installés en permanence. Ces méthodes traditionnelles nécessitent souvent une mobilisation et accès au site coûteux pour les véhicules plus gros par rapport aux méthodes plus modernes. La combinaison de l'instrumentation traditionnelle et des technologies de surveillance permet de mieux comprendre les dangers et d'élaborer des stratégies de réduction des risques. Ces technologies constituent un moyen économiquement instrumentation. Cet article présente l'application du système de détection et de télémétrie par la lumière et du système de positionnement global différentiel afin d'améliorer les archives historiques éparses et de mieux comprendre le développement, la progression et les mécanismes des glissements de terrain. Un certain nombre de problèmes liés à leur utilisation dans les glissements de terrain végétalisés à déplacement lent sont également abordés. Comme étude de cas, terrain Chin Coulee.
