Hydroelectric Romaine Complex |
In May of 2004, Hydro-Québec has mandated Poly-Géo to investigate the geomorphic aspects of the environmental impact study of a new hydroelectric project, the Romaine Complex. Poly-Géo was responsible for the assessment of two constituents leading to the environmental impact study. The first one addressed the geomorphic characterization and sensitivity to erosional processes of the area. The second one addressed the fluvial sedimentary dynamics of the Romaine river watershed.
The main objective of this study is to provide the best possible understanding of the actual sedimentary processes and hence evaluate potential impacts from the Romaine Complex on the physical environment. This study included a number of detailed activities:
- within a wide corridor, 1 km on each side of the Romaine river and of the projected reservoirs, air-photo interpretation and mapping (scale of 1: 20,000) of surficial materials, landforms, and areas of high erosional sensitivity of the land,
- detailed air-photo interpretation and mapping (scale of 1: 5,000) of the surface materials, landforms and high erosional sensitivity of the land in the future modified portions of the river,
- mapping of erosion potential of the future shorelines of the projected reservoirs,
- investigation of the Romaine river sedimentary dynamics,
- impact analysis and mitigation proposals if needed.
