Coasts

Sector Overview

There is strong momentum across the Northeast toward adaptations aiming to improve coastal resilience, and strong demand for quantification of these adaptations using hydrodynamic models.

The CCRUN coasts sector team is lead by Dr. Philip Orton at Stevens Institute of Technology.

 

 

Phase I Highlights 

Collaboratively working with the City of New York on their post-Sandy resiliency plans, the coasts team learned of the stakeholder need for layered resilience (redundancy), instead of only vertical approaches like levees.

The coasts team provided the City of New York with the flood modeling of grey and green shoreline adaptation measures and evaluated what coastal adaptations would stop a 100-year flood with sea level rise.

Won the federal Housing and Urban Development “Rebuild by Design” competition in part due to taking the layered resilience approach much further, including physical, social, regulatory, educational and ecological resilience layers.

 

Phase II Highlights

The coast sector plans for Phase II of CCRUN were aimed at one focal point: informed and improved decision-making on coastal urban resilience. The team also planned to measure the impact of structural and nature-based coastal adaptations on flood risk and water quality for Jamaica Bay.

Phase II returned valuable data for decision and policy-makers, including the assessment that today’s 100-year flood of 2.7 m is 25 times more likely at the 2080s. This result starkly contrasts the most recent NCPP report, which published that storms of this magnitude are only 3 times as likely to occur by then end of the century. These new and acute results are products of CCRUN research innovation, including the use of different methods for incorporating sea level rise uncertainty and the incorporation of tropical cyclone climatology changes.

Additionally, CCRUN researchers have ascertained that Jamaica Bay climate adaptation scenarios of sedimentary restoration can lead to substantial reductions in storm tides as well as a lessening of the impacts of future climate warming on hypoxia.
