2. Climate Change Assessment: Methodology Global Circulation Models Projections of Meteorology Under Climate Change Hydrology Models of Basin Projections of Streamflow Under Climate Change Simulation and Optimization Models Impacts of Climate Change on all Watershed Objectives!

3. Climate Change Data • Global Circulation Models (GCMs) provide predictions of climate (precipitation and temperature) for the future • Different CO2 emission scenarios are generated by these models to account for possible future scenarios

6. Generate Streamflow Using Hydrology Model • Build a hydrology model of the Connecticut River watershed • Force this model with climate impacted meteorology • Generate climate-change impacted streamflow

7. Use SYE Method to Develop Basin-Wide Streamflow • Identify climate impacted streamflows at index gages for SYE • Use SYE methodology to generate climate impacted streamflow timeseries at inflow points throughout Connecticut Basin
