# The wave height result of STWAVE

## Recommended Posts

In STWAVE's document it said that the result of STWAVE is "Zero-moment wave height",Hm0,I want to know that what does the "Zero-moment wave height "

mean?

Hm0=SQRT(m0) or Hm0=SQRT(2*Pi*m0) ?

Thanks!

the input wave condition of STWAVE: in tool bar "Spectral Energy" select creat grid and then Generate Spectra,then in the "Spectral parameters" we must write

in "index","Angle","Hs","Tp"...,

and my question is What does Hs Mean? It means "Significant Wave Height"?

Thanks again!

hycc_sms,

Hs is the incident zero moment wave height. Here is a link that explains what each item in the "Generate Spectra" dialog is:

As for the "zero moment wave height," I would refer you to the STWAVE documentation. Here is the link:

But there is no information about how does the Hm0 be computated?

Hm0 is the Square root of m0 multiplied by 4?

That's it...

Excuse me hycc_sms, but I can't understand why are you using STWAVE if you don't know some basic concepts like what's Hm0 and/or the way it is calculated.

An explanation of significant wave height can be found on wikipedia http://en.wikipedia.org/wiki/Significant_wave_height
