Sudicky, S.K. Frey, H.-T. Hwang & Y.-J. Park Aquanty, Inc., Waterloo, Ontario, Canada Department of Earth and Environmental Sciences, University of Waterloo, Waterloo, Ontario, Canada Climate change will greatly impact the availability and quality of Earth’s water resources over the next century. The expected increase in mean temperature may have a severe impact on the water cycle, not only through changing precipitation patterns and amounts, but also through an increase in the severity and frequency of extreme events. Unforeseen changes in rainfall patterns and shifting temperatures will exacerbate water management in the Grand River watershed, thus affecting the programs and operations of the Grand River Conservation Authority (GRCA). The main objective of this study is to analyze the impact of climate change forecasts on the surface and subsurface water resources within the Grand River Watershed, which is one of the more heavily populated water basins in Canada. A high-resolution 3D integrated surface-subsurface hydrological model, Hydro- GeoSphere (HGS), is first calibrated against the extensive surface and subsurface hydrologic data collected within the watershed over the past decades. Next using dynamically downscaled climate projections to drive HGS, the calibrated integrated hydrologic model is used to assess the impacts of climate change on both the surface and subsurface flow regimes within the Grand River Watershed over the next century. 224 - Strategies for Integrated Model Calibration J.D.C. Kassenaar, E.J. Wexler, P.J. Thompson & M.G.S. Takeda Earthfx Incorporated, Toronto, Ontario, Canada Integrated modelling has emerged as the preferred approach to address complex watershed management, cumulative impact and engineering-scale problems such as mine or quarry development. As groundwater scientists, using an integrated model requires us to re-evaluate our assumptions and simplifying approaches previously used for surface water analysis and shallow sub-surface interactions. In a related initiative, the surface water community recently completed a 10 year effort to assess strategies and approaches for predictions in ungauged basins (PUB). In a summary of this initiative, Hrachowitz et. al. (2014) noted the need for “a major paradigm shift in scientific hydrology, traditionally rooted in empiricism and…data- and calibration focused methods to methods that are more strongly based on theoretical insights into physical processes and system understanding”.
