This presentation will describe how to incorporate biogeophysical impacts of climate change into future tide and surge models. A methodology will be presented to down select a suite of synthetic storms from recent flood insurance studies to force hurricane storm surge models that represent present day and future changes to the coastal landscape under four sea level rise (SLR) scenarios of low (0.2 m), intermediate-low (0.5 m), intermediate-high (1.2 m), and high (2.0 m). Results of peak storm surge are used to compute the 100-year and 500-year return period floodplain and stillwater surge heights for each SLR scenario.
