An System Approach for Assessing Climate Change Impact on Watershed-based Hydrologic Process and Reservoir Water Dynamics
This study tries to investigate potential impacts of climate change on watershed-based hydrologic processes and reliability of water resources. System Dynamics is employed as an effective methodology to organize and integrate existing information available on climate change scenarios, watershed hydrologic processes,reservoir water dynamics and water resource assessment system. The general Global Climate Model (GCM) is selected to generate the climate change scenarios with daily climate change data for hydrologic modeling.Watershed-based hydrologic and reservoir water dynamics modeling focus on dynamics processes of both streamflow formation within the watershed, and the reservoir water dynamics under reservoir operation rules. The reliability measure describes the effectiveness of present reservoir operation rules to meet different demands. Finally the model was applied in Northern American Prairie to assess the impacts of two climate change scenarios on the reliability of water resources.
