Session: GEOHAZARDS - III Climate Change Floods & Landslides

ABSTRACT: We combine surface displacements derived from satellite-based Interferometric Synthetic Aperture Radar (InSAR) with geomechanical models to assess geohazards near two pipeline corridors: a pipeline right-of-way in central British Columbia and a slope adjacent to Fels Glacier in Alaska. The geomechanical models are based on published geological data and aerial and ground photographs, and are constrained with InSAR-derived displacements and slope inclinometer data.

RÉSUMÉ: Nous combinons des mouvements de surfaces déduits des techniques de radar interférométriques à ouverture synthétique (InSAR) obtenues à partir de satellites avec des modèles géomécaniques pour évaluer les aléas géologiques près de deux couloirs de droit de passage de pipeline en Colombie-Britannique centrale et un versant adjacent au Glacier de Fels en Alaska. Les modèles géomécaniques sont fondés sur les données géologiques publiées et des photographes aériennes et terrestres, et les mouvements obtenus des techniques InSAR et des données mètre de pente sont utilisés pour restreindre les modèles.
