Hi,
I'm Navisa from Bandung Institute of Technology - Indonesia. I'm a senior student majoring in physical Oceanography and now I'm in the middle of preparing for my final assignment research. My focus of study related to ocean wave phenomena and I wonder to use ANUGA for wave model because no one ever use this model before. Do you have any recommendation for specific research topic that can I use for my final assignment? Can I predict wave high and wave direction in shallow water also ?
I hope I can use ANUGA as a tool for my research.
Thank you and really looking forward for the next information

Hi Navisa,
ANUGA solves the shallow water equations, which are usually a good approximation of waves when the wavelength is large compared with the water depth (say > 20 times larger). Now, for ocean swell, I imagine the wavelength is typically smaller than the flow depth -- and in this case, the shallow water equations are not appropriate, and ANUGA is not the right tool.
Typically the shallow water equations are used for things like ocean and estuarine tides, tsunami, storm surges, floods, etc. In all these cases, the spatial scales over which the flow varies are usually much larger than the flow depth -- with some exceptions [e.g. in tsunami, you can have shorter period waves generated by non-hydrostatic effects, and ANUGA cannot model these]. I have also seen studies using the shallow water equations to study ocean wave runup on beaches -- so there are some coastal wave type applications as well.
I'm not an expert in ocean waves, but I know people often use the open source 'SWAN' wave model, particularly for waves in coastal regions. In the deeper ocean, I know of the open source 'WAVEWATCH3' code which you might check out.
Maybe someone else on the list has more expertise in ocean waves, and can point you to other options.
Best of luck with your research project.
Cheers,
Gareth.

Hi Navisa and all,
Just to complement what Gareth just said.
SWAN is appropriate if you want to model the transformation of the spectrum
of the waves, this is, its energy distribution over frequencies and
directions. However, if you intend to model the free surface movement as it
is, this is solve each individual wave, you need a phase resolving model,
similar to ANUGA but that incorporates the non hydrostatic terms that are
present in short waves. In that cases models like SWASH are more suitable.
Both are open source and freely available, and you can check them here:

Hi, thank you for all your information. I think I am going with SWAN + ADCIRC model for doing my final assignment project.
I hope I can learn and use ANUGA someday, and maybe in my master thesis.
Really appreciate your help
cheers :)
