- •
The non-linear changes to uni-directional wave-groups are studied.
- •
A potential flow model and the broadbanded modified non-linear Schrödinger are compared.
- •
The MNLS agrees with fully non-linear simulation for waves a moderate steepness.
- •
Local non-linear broadening of the spectrum limits the accuracy of the MNLS.
