Abstract

Assessing Coastal Flood Risk Responding to Projected Changes in Sea-level
Track: Climate Change and Conservation
Authors: John Dorman

The North Carolina Sea Level Rise Risk Management Study (NC SLRRMS) is studying the change in risk to build/living systems. The study is evaluating changes in hazards at a range of sea levels through 2100. Multiple future scenarios are being appraised at four time slices (years 2025, 2050, 2075, and 2100).
The projected impacts will be used to estimate a range of risk metrics. These estimates will allow development of a risk portfolio across the range of potential climate and development scenarios. The study will identify and evaluate flood risk management strategies to reduce vulnerablity to the predicted chage in flood hazard. Finally, tailored decision metrics will be used to rank and recommend adaptation policy and strategies to the North Carolina General Assembly and FEMA.
This presentation will include an overview of methodologies for climate scenario development, future geomorphologic scenarios, and land use/development scenarios.
