Learn about tidal flooding and how it is incorporated in the Flood Model.

 

Definition

Tidal flooding, also known as sunny day flooding, king tide flooding, and nuisance flooding, is the temporary flooding of low-lying areas near a coast. Tidal flooding usually occurs through the combination of winds, offshore storms, and full moon cycles during high tide events such as full moons and new moons. At-risk areas can experience this flooding multiple times a year. Tidal flooding is incorporated into our models through the addition of coastal tide gauge station readings to adjust local water levels for integration into our modeled flood risk layers.
