Particle Motion in Surface Gravity Waves

Fluid particles in translating surface gravity waves have an orbital motion which decreases size with increasing mean depth. These wave characteristics came from observations and were not forecast theoretically. The classical potential flow model is incapable of explaining the particle movement due to the irrotational assumption a flaw carrying out method. When wave passes by observer from left right, particles move clockwise under a crest trough. This correct conclusion consistent what the incorrect standard theory implies but should be considered been derived it.
