THAW SETTLEMENT of DEGRADING PERMAFROST: a GEOHAZARD AFFECTING the PERFORMANCE of MAN-MADE INFRASTRUCTURES at UMIUJAQ in NUNAVIK (QUÉBEC) Richard Fortier, Ing., Ph.D
THAW SETTLEMENT OF DEGRADING PERMAFROST: A GEOHAZARD AFFECTING THE PERFORMANCE OF MAN-MADE INFRASTRUCTURES AT UMIUJAQ IN NUNAVIK (QUÉBEC) Richard Fortier, ing., Ph.D. Centre d’études nordiques, Université Laval, Québec, QC, Canada, G1V 0A6, [email protected] Maxime Bolduc, ing. jr. INSPEC-SOL, Montréal, QC, Canada, H4S 1C7 RÉSUMÉ La dégradation du pergélisol dans les régions nordiques peut provoquer des risques naturels comme la subsidence au dégel qui affecte la performance des infrastructures civiles. Par exemple, le long d’un segment de 300 m de longueur de la route d’accès à l’aéroport d’Umiujaq au Nunavik (Québec), trois zones de subsidence au dégel ont été étudiées durant l’été 2006; soit 15 ans après la construction de la route. La subsidence atteint par endroit jusqu’à 0,63 m pour un volume total de près de 530 m3. Des levés de géoradar et un profilage de résistivité électrique ont été réalisés afin de caractériser la stratigraphie du sous-sol et les conditions du pergélisol. Le dégel de sédiments marins gélifs sur une épaisseur d’au moins 4 m sous les zones de subsidence a provoqué un tassement et une diminution de l’indice des vides d’environ 15%. Le tassement au dégel est non seulement provoquée par la tendance au réchauffement climatique récemment observée au Nunavik mais aussi par l’accumulation de la neige le long de la route. Le couvert nival isole ainsi la surface du sol et prévient tout regel du sous-sol en hiver. Alors que la route est toujours carrossable, la seule mitigation économiquement viable au dégel du pergélisol est de laisser libre cours au tassement au dégel et de recharger le remblai lorsque cela est nécessaire jusqu’à sa stabilisation. -

Protecting the Nastapoka River – a Multicultural Approach to Sustainability
Geophysical Research Abstracts Vol. 21, EGU2019-3379, 2019 EGU General Assembly 2019 © Author(s) 2019. CC Attribution 4.0 license. Protecting the Nastapoka River – A Multicultural Approach to Sustainability Arielle Frenette and Najat Bhiry Centre for Northern Studies (CEN), Dép. de géorgaphie, Université Laval, Canada This presentation aims to describe and analyze a case study concerning the creation of a 27,000 km2 national park near the village of Umiujaq, Nunavik (Northern Québec). The aim of the park is to protect the Nastapoka River and the majority of its watershed from mining and hydroelectric development projects. With a 30 m high waterfall near its mouth, the Nastapoka River is of great importance to the region as it is part of the ancestral Inuit land as well as a habitat for the world’s only population of freshwater seals. It is located on Inuit and Cree territory, whose people hunt and fish in the area. The river was first targeted by Hydro-Québec (a provincial hydroelectricity company) for a mega-complex project called Grande-Baleine, but that was set aside by the government of Québec in 1994. In 2008, an important development project named Plan Nord was announced by the government of Québec. Plan Nord was implemented in 2011 to provide access to natural resources in Northern Québec. It aims to protect 50% of northern natural land – an objective that was largely denounced as a form of “compensation” so that Plan Nord could be held up as an “exemplary project of sustainable development”. National park projects were already underway in Nunavik. -

Stream Turbidity Within Degrading Permafrost Terrain in the Tasiapik Valley, Umiujaq Region, Nunavik
Geophysical Research Abstracts Vol. 21, EGU2019-2753, 2019 EGU General Assembly 2019 © Author(s) 2018. CC Attribution 4.0 license.

For example, it contributes to greenhouse gas emissions, increased recurrence of landslides, and changes in water resources. Sediment migration to the soil surface has also been observed during soil settlement caused by thawing permafrost. Soil settlement increases the flow of water, which is enriched in organic matter and mineral sediments, toward streams and lakes, resulting in increased suspended sediment load and increased river turbidity. Furthermore, during flood episodes in spring and high rainfall in autumn, the loose sediment is supported and transported toward the river by surface runoff. This increase in turbidity can have negative effects on the trophic chain, especially on fish as a result of the abrasion of their gills. Variations in river turbidity have been examined in several studies (Lawler et al., 2006; Hamilton and Luff- man, 2009). However, in the context of current and future climate change, there is limited knowledge about the effects of variations in river turbidity associated with permafrost degradation. -

Processus Gravitaires Dans La Vallée Tasiapik (Nunavik) : Témoins Géomorphologiques De La Dynamique De Versant Récente Et Passée
Processus gravitaires dans la vallée Tasiapik (Nunavik) : témoins géomorphologiques de la dynamique de versant récente et passée Mémoire Samuel Veilleux Maîtrise en sciences géographiques - avec mémoire Maître en sciences géographiques (M. Sc. géogr.) Québec, Canada © Samuel Veilleux, 2019 ii Résumé Ce projet de recherche, mené près d’Umiujaq (Nunavik), a été réalisé afin de documenter les processus gravitaires dominants qui se manifestent sur les versants escarpés de la vallée Tasiapik. Des relevés topographiques, granulométriques, morphométriques, pétrographiques et de végétation ont permis de caractériser 18 talus d’éboulis situés sur les versants sud-ouest et nord-est. Les résultats obtenus ont permis d’établir que l’éboulisation importante sur les versants de la vallée est un phénomène à la fois ancien, engendré par des processus paraglaciaires, et récent, résultat de processus périglaciaires toujours actifs aujourd’hui. Cela se traduit notamment par différents stades de développement des talus d’éboulis subactuels, illustrés par certains dépôts de versant frais et d’autres très anciens, mais aussi avec des topographies de pente très variables. Sur une échelle de temps plus courte, entre août 2017 et juillet 2018, les avalanches se sont avérées être un processus majeur, tel qu’observé sur les 14 000 photographies obtenues grâce à trois caméras à déclenchement automatique installées à l’été 2017. Ces avalanches, souvent déclenchées par des chutes de corniches à neige, ont été particulièrement fréquentes au printemps 2018, résultant de conditions météorologiques propices telles qu’une hausse rapide des températures journalières et des épisodes de pluie abondante. Des dépôts d’avalanches sales témoignent d’une grande capacité érosive, et incidemment de leur grand apport en débris vers les talus d’éboulis.
