Description: Hydrological simulations under climate change scenarios can be a useful tool to understand how a change in global climate could affect the availability and variability of regional water resources and water quality. The main goal of current study is to assess the impacts of climate change on water resources and sediment loads in cold climate condition of Ontario. The Soil and Water Assessment Tool (SWAT) was selected to evaluate the impacts of climate change in Canagagigue Creek watershed in Ontario. The climate scenario under consideration in this study is based on CRCM, PRECIS which generated outputs under A1B for Ontario corresponding to the baseline (1960-1990), mid-century (2015-2065) and end-century (2065-2095). The results demonstrated that SWAT model adequately simulated the hydrology and water quality of the watersheds and performed satisfactory results. SWAT simulations results indicate that for the Canagagigue watershed, in general, the climate of the study area will be warmer and wetter. The increase in min/max temperatures in winter leads to more rainfall-dominated regime and less snowfall. This will result an increase in length of the growing season. Therefore, the climate change seems to alter both magnitude and seasonality of flow. In general climate change effects more spring and winter hydrology than summer hydrology. The results show that the annual flow is expected to increase significantly in future, which leads to an increase in the sediment load at the in the stream.
