March 21, 2024: 1-2PM ET: NRCAN Webinar Series – CANADA1WATER OVERVIEW: A NATIONAL-SCALE HYDROCLIMATOLOGICAL MODELLING INITIATIVE FOR CLIMATE CHANGE IMPACT ANALYSIS

Presenter: Steven Frey

Assessing the impact of climate change on Canada’s water resources requires a national solution that considers both groundwater (GW) and surface water (SW). The Canada1Water (C1W) initiative addresses this need through the use of HydroGeoSphere (HGS) fully-integrated GW-SW models that collectively provide complete coverage for drainage basins over continental Canada and Baffin Island. In addition to HGS, C1W is utilizing regional climate modelling conducted with the Weather Research and Forecasting (WRF 4.3) model and land surface modelling conducted with the Community Land Model (CLM 5) to generate future climate projection ensembles and thermal regimes for the GW-SW models. Results from C1W will help quantify changes in surface and subsurface hydrologic conditions at mid- and end-century time frames under an ensemble of climate projections. C1W model data sets and model outputs will be published under an OpenGovernment Data licence. This presentation will provide an overview of the C1W model and dataset development, and how to access the resultant data
