Significant wave height of a swell
WebWave/swell heights can best be estimated when the ship’s rolling and pitching is least. The wave/swell height is then the height of the observer’s eye above the ship’s water line … WebThis study predicts significant wave height using the machine learning (ML) technique with generalized extreme value (GEV) theory and its application to extreme wave analysis.
