The impacts of climate-induced changes in discharge and base level in 3 tributaries of the Saint-Lawrence River, Québec, are modelled for the period 2010–2099 using a one-dimensional morphodynamic model. Changes in channel stability and bed-material delivery to the Saint-Lawrence River over this period are simulated for all combinations of 7 tributary hydrological regimes (present-day and those predicted using 3 global climate models and 2 greenhouse gas emission scenarios) and 3 scenarios of how the base level provided by the Saint-Lawrence River will alter (no change, gradual fall, step fall). The different results highlight the importance of investigating several rivers using several climate models in order to determine trends in climate change impacts
