Story Highlights

Researchers from NOAA and William & Mary have developed the first three-dimensional operational storm surge model.

SCHISM (Semi-implicit Cross-scale Hydroscience Integrated System Model) simulates compound surge and flooding, which is especially challenging in transition zones where the river meets the sea.

Since April 2021, NOAA has run daily 2D and 3D compound flood modeling on Frontera at TACC. During Tropical Storm Claudette (June 2021), water level results from the three-dimensional, real-time storm surge model closely matched observations across the Gulf Coast.
