Local and global features of resonant third-order interactions amongst surface gravity waves

Thesis

The formation of 'rogue' or 'freak' waves at the ocean surface is an important consideration for engineering design since such waves represent the worst-case scenario for structures in the ocean. Extreme wave events can be formed by the linear mechanism of dispersion, due to constructive interference between propagating wave components with different frequencies and directions. Nonlinear energy transfers between wave components can, however, alter the shape, kinematics and lifespan of an e...
