Abstract

The Centre d'Expertise Hydrique du Quebec (CEHQ) manages dams used for flood control, water supply, recreational activities and hydroelectricity in the province of Quebec. This paper addressed the issue of global warming and the impact on the hydrological regime within the next decades. The changes in the hydrological regime may pose a risk of losing the equilibrium between various objectives, identifiable through water management plans. The CEHQ conducted a pilot study for the Saint-Francois and Aylmer reservoirs in order to formulate a method for evaluating the adaptability of currently used management plans to climate change. The project was based on potential climate change scenarios as well as on deterministic and distributed hydrological models. Daily time steps were used to evaluate the hydrological impacts of climate change. The newly developed model makes it possible to evaluate and compare the occurrences where stream flows and water levels exceed critical values. The effectiveness of the management plans in both current and climate change scenarios was evaluated. Preliminary results suggest a possible increase in flood risk and fewer low water level occurrences. It was concluded that climate change will influence the trade-off between different management objectives of the reservoirs. Although adaptation measures may be  More>>
