Master’s Project at INRS : Analysis of the effect of flooding Lake Manicouagan by Daniel-Johnson Dam on lake sedimentation

The goal of this project is to analyze sediment cores collected from the Manic-5 reservoir to: (i) understand the hydro-sedimentary dynamics of a large reservoir in a boreal environment; (ii) assess the morpho-sedimentary impacts of flooding a former natural lake through the commissioning of a reservoir; (iii) reconstruct the physical landscapes of the ancestral territory since the Deglaciation.

The specific objectives of the student will be:

  1. Participate to field work to collect cores in the reservoir of the Daniel-Johnson Dam.
  2. Analyze the physico-chemical properties of the cores using state-of-the-art techniques (CT, microXRF, and hyperspectral scans) and conventional techniques (granulometry, organic matter and water content).
  3. Obtain an age model for the cores.
  4. Identify links between sediment properties and (i) natural environmental variations, (ii) Innu activities on their ancestral territory, (iii) industrial activities in the watershed, and (iv) dam construction.

The project will benefit from state-of-the-art research infrastructure (Multidisciplinary CT Scan Laboratory and Geochemistry, Imaging, and Radiography of Sediments Laboratory) and from the assistance of the INRS laboratory team.

This project is part of the multidisciplinary project “Dynamics of the Innu ancestral territory (Nitassinan) through the morpho-sedimentary and socio-cultural study of Lake Manicouagan (Reservoir)” funded by the Institut nordique du Québec and the Sentinel North Strategy. It will benefit from numerous collaborations: the Innu community of Pessamit, the Manicouagan-Uapishka World Biosphere Reserve, the Ndakina office of the Waban-Aki Nation, Caroline Desbiens and Justine Gagnon of the SSHRC Canada Research Chair in Indigenous Heritage and Tourism.
