NOAA Digital Coast – How to Calculate Coastal Flood Frequency

Use this guide to walk through the process of how to calculate and plot coastal flood frequency. Primary intended audience: planners, engineers, etc. This guide outlines steps for calculating customized scenarios of local coastal flood frequencies using the same methods as NOAA’s Sea Level Rise Viewer. The tool uses flood threshold data from the National Weather Service and the Inundation Analysis Tool from NOAA’s Center for Operational Oceanographic Products and Services.
