Hence, this study evaluates the ability of a standard hydrologic model set - up: Variable Infiltration Capacity (VIC) hydrologic model for two
headwater sub-basins in the Fraser River (Salmon and Willow), British Columbia, Canada, with climate inputs derived from observations and statistically downscaled global climate models (GCMs); to simulate six general water resource indicators (WRIs) and 32 ecologically relevant indicators of hydrologic alterations (IHA).
Both observational data and statistically downscaled global climate model output were used and the regions chosen were the Salmon and Willow
headwater sub-basins in the Fraser River, in British Columbia.
