November 2020 Project Update

Register for the Resilient Connecticut Nov. 20th Summit
While waiting for today’s election results, why not REGISTER for the second Resilient Connecticut Summit to be held on November 20, 2020? This half-day, virtual event is open to the public and free to attend. Participants will learn about CIRCA’s recent Resilient Connecticut project activities, participate in breakouts with partners, and hear from a keynote speaker. View a detailed agenda on the Summit Website and register by November 17 (a link to join the event will be sent to registrants on November 19). This event is eligible for 2.75 hours of CM credit through the Connecticut Chapter of the American Planning Association.
Resilient Connecticut Stakeholder Evaluation Survey Closed Nov. 1st
Dr. Miriah Russo Kelly, Assistant Professor in the Dept. of Environmental, Geography, and Marine Sciences at Southern Connecticut State University, worked with the CIRCA team to develop a stakeholder evaluation survey. The survey was distributed to a variety of organizations that may use or be impacted by the Resilient Connecticut project. The survey was designed to assess their interests, needs, and preferences. The results will inform the products and planning process for the project. If you have any questions about the survey, please email Dr. Miriah Russo Kelly. If you have questions about the Resilient Connecticut project, please email CIRCA’s Dr. Joanna Wozniak-Brown.
New Dataset Models Long Island Sound Extreme Storms
A coastal circulation and wave model (FVCOM-SWAVE) for the highest 44 storms between 1950 and 2018 is available for Long Island Sound. The hourly outputs of water level and wave height from 44 simulations in NetCDF format are provided (NetCDF data covers Long Island Sound, Block Island Sound, and the adjacent shelf south of Long Island). The duration for each storm simulation is between 5 to 8 days. As described in a recent journal article the North Atlantic Coast Comprehensive Study (NACCS) mean results “are higher for water levels and lower for significant wave heights for longer return periods” compared to CIRCA’s model. Comparison with the FEMA results also show differences in eastern and western LIS. In addition to evaluating historic risks, CIRCA also added a sea-level height offset of 20 inches for 2050 estimates in order to examine the effect of rising sea-levels on the analysis. “We find that sea-level rise reduces the return period of a ten year storm to two years.” To help decision-makers better understand extreme storms, CIRCA now has products available from this study (please email CIRCA’s Dr. Yaprak Onatwith questions):
