Impacts of freshwater flow regulation of Quebec’s large rivers on the physical environment and krill transport in the Gulf of St. Lawrence and on the Scotian Shelf / by Diane Lavoie ... [et al.].: Fs97-18/318E-PDF

"We use a three-dimensional numerical circulation model and river runoff from a hydrological model to assess the large-scale impacts of harnessing Quebec’s large rivers on the dynamics of the Gulf of St. Lawrence and Scotian Shelf. We first look at the impact of harnessing a single river (St. Lawrence River, Romaine River) or a subgroup of rivers (Saguenay, Manicouagan, Betsiamites, and Outardes rivers; Romaine and Little Mecatina rivers), and finally at the cumulative impact of harnessing all these rivers. Most of the rivers are already harnessed, dams are currently under construction on the Romaine River, and harnessing of the Little Mecatina River is at the planning stage. We analyzed the changes brought to the top 50 m of the water column in terms of salinity, temperature, and circulation. Transport at different cross sections was also analyzed as well as the sea-ice conditions. Lastly, we looked at the impact of changes in circulation and turbidity on krill transport and mean density in specific regions of the Gulf of St. Lawrence"--Abstract, p. xi.
