Session ID#: 27168

Session Description:
Fringe wetlands and wetlands islands can reduce wave height and store floodwaters during storms. As a result wetlands restoration and creation are increasingly being proposed as a resilience strategy for coastal communities that also enhances ecosystem health. This living shorelines approach requires design and engineering based on climate science as well as engagement of regulators and communities to successfully implement projects. Questions remain about the design of these wetlands, especially on how to incorporate adaptation to sea level rise. Projects may also utilize thin layer deposition of dredged sediments, which has both significant design and regulatory hurdles. Finally, there is a need for in situ observations or models for evaluating the performance of wetlands as a resilience strategy during storms and under sea level rise scenarios. This session invites presentations on case studies, models and measurements to evaluate resilience, and policy and communications approaches to implement projects.
