Flow Modeling at Dam Removal Sites Associated with Hurricane Sandy Resiliency Efforts

Science Center Objects

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.
