摘要

This thesis describes an approach to examine how the management of a large system of reservoirs could decrease environmental alteration from unregulated (no dam) conditions. A reservoir system simulation model was used to model current operations at 73 reservoirs and flows at ecologically significant points in the Connecticut River watershed. The regulated flows from the simulation model were then compared to the unregulated flows using ecological metrics based on specific annual inundations required by floodplain plant communities and flow targets developed by experts for migratory diadromous fish species. The process identified (1) trends in environmental alteration for the Connecticut River mainstem and (2) potential reservoir management changes to reduce environmental alteration while analyzing changes in hydropower generation. Different scenarios were then simulated to assess potential reductions in environmental alteration and potential losses in hydropower generation and flood risk management. The approach described in this thesis could be applied to other watersheds to assess environmental alteration from dams and assist in watershed planning and environmental flow implementation.
