The purpose of this work is to better understand the effects of dam removal on local hydraulics, fish passage, and flooding. This study is part of a larger effort to monitor ecological resilience changes at nine Hurricane Sandy coastal resiliency aquatic connectivity restoration projects. It will contribute crucial knowledge that will be used to improve aquatic connectivity system cost-effectiveness and functionality.
Hydraulic models will be constructed for nine aquatic connectivity restoration sites: White Rock Dam (CT/RI), Bradford Dam (CT/RI), Pond Lily (CT), Hyde Pond (CT), Bloede Dam (MD), Wreck Pond (NJ), Hughesville (NJ), Whittendon (MA), and West Brittania (MA).
All data will be integrated into one- and two-dimensional hydraulic models for both pre- and post- dam removal scenarios. Models will be used to visualize local hydraulics, to assist in the creation of flood inundation maps, and ultimately to assess whether biological objectives for fish passage through improved hydraulics have been achieved.

Aquatic connectivity projects, such as removing dams and modifying culverts, have substantial benefits. The restoration of natural flow conditions improves water quality, sediment transport, aquatic and riparian habitat, and fish passage. These projects can also decrease hazards faced by communities by lowering water-surface elevations of flood waters and by removing the risk of dam breaches assoc
