fullydevwave#
[EhatFullyDev, fphatFullyDev] = fullydevwave(CalcMethod, windvel)
Description#
Calculate a fully developed condition for wind wave growth
Inputs#
- CalcMethod=’pierson’;
- Parametric wave model to be used for calculation‘pierson’: Use method by Pierson and Moskowitz (1964)‘spm’: Use method by Shore Protection Manual (SPM), U.S. Army Corps of Engineers (1984)‘cem’: Use method by Coastal Engineering Manual (CEM),U.S. Army Corps of Engineers (2015)
- windvel=0;
- Wind velocity in (m/s)Wind velocity should be measured (or represents velocity) at 10 m above surfaceFor ‘cem’ and ‘spm’ methods, wind velocity should be converted to duration of sustained wind by using gust factor
Outputs#
- EhatFullyDev
Dimensionless wave energy for a fully developed condition, Ehat=g^2*m0/U10^4
- fphatFullyDev
- Dimensionless peak wave frequency for a fully developed condition, fphat=fp*U10/9.81Note, g=9.81: gravitational accelerationU10: wind velocityfp: peak wave frequencym0: Zero-moment of water surface elevation power spectral density
