Wavelength: the distance between two identical points on successive waves, for example crest to crest, or trough to trough. Wave steepness: the ratio of wave height to length (H/L). If this ratio exceeds 1/7 (i.e. height exceeds 1/7 of the wavelength) the wave gets too steep, and will break.

Jun 10, 2024 · Wavelength: the distance between two identical points on successive waves, for example crest to crest, or trough to trough. Wave steepness: the ratio of wave height to length (H/L). If this ratio exceeds 1/7 (i.e. height exceeds 1/7 of the wavelength) the wave gets too steep, and will break.
The wave steepness is defined as the ratio of wave height H to the wavelength λ. The wave properties are made dimensionless using the wavenumber k = 2π / λ , gravitational acceleration g and the fluid density ρ .
Wavelength can be found by measuring the distance between two identical parts of a wave. For instance, the distance between two wave troughs or two wave crests. The longer the wavelength, the faster that wave will be. The steepness, then, is the wave’s height to length ratio.
Feb 15, 2021 · Wave steepness is the ratio of height to wavelength. When wave steepness exceeds a ratio of 1:7, breakers form. Example: If a moving wave has a height of one foot and a length from crest to crest of 8 feet, then the ratio is 1:8 and this wave is not going to break.
Wave steepness is calculated using the formula: $$S = \frac{H}{L}$$, where H is the wave height and L is the wavelength. A wave steepness greater than about 1:7 (or approximately 0.14) is often associated with instability and can lead to wave breaking.
As wind energy increases, the waves receive more energy and they get both larger and steeper (recall from section 10.1 that wave steepness = height/wavelength). When the wave height exceeds 1/7 of the wavelength, the wave becomes unstable and collapses, forming whitecaps.
