Non-linear interaction modulates global extreme sea levels, coastal flood exposure, and impacts

A. Arns, T. Wahl, et al.

This groundbreaking study reveals a novel statistical approach to understanding the non-linear interactions of tide and non-tidal residuals in extreme sea levels. Researchers found that ignoring these interactions could result in significant overestimations of sea level risks, highlighting the need for accurate assessments. This transformative research, conducted by Arne Arns, Thomas Wahl, Claudia Wolff, Athanasios T. Vafeidis, Ivan D. Haigh, Philip Woodworth, Sebastian Niehüser, and Jürgen Jensen, offers vital insights into flood risk and coastal impact assessments.
