Hello,

I would like to know if it's possible to lauch a simulation of agitation with artemis wich includes a stationnary wind and current.

Thank you !

hello

I don't find anything for putting stationnary current or wind with artemis. I would like to study the impact of tidal current or/and stationnary wind on the agitation.
I don't found anything in the sources. Has someone ever studied those impact ??

thanks a lot !!

hello,

I found a presentation of Michel Benoit realized on december the 8th and 9th, 2008. The aim of this presentation was to demontrate that curents have an impact on swell agitation. It's said that the currents will be include on agitation simulation with artemis by changing equations of berhkoff.
anybody knows if I can find fortran code or something else to include current in my simulations ?

Thanks a lot for your help !

Hello,

To my (limited) knowledge, the latest evolution of Artemis concerned the evolution of bathymetry, so I am not quite sure that the development you mention has been implemented yet.

With best regards,

Hello there,

starting from Berkhoff's equation, it is possible to derive a new form from it that takes into account the presence of currents (Liu 1990).Nevertheless this is not a trivial procedure, and as far as I know, there is not yet a fortran subroutine that modifies the ARTEMIS module so as to consider currents (in fact, I think of this as a new release of the ARTEMIS featuring the 'currents' form,rather than a subroutine).

Regarding the wind, you should bear in mind that ARTEMIS is a phase-averaged model. Historically, although attemps have been made to include generation or decay, the results have been disappointing, and therefore not included in this kind of models (those based on Berkhoff's equation). During the last years it seems that there have been some success including wind as forcing to a phase-averaged model, but for Boussinesq-type models only (see Chen 2004).

To sum up: currents can be added, but it seems to be more a revision of the whole ARTEMIS module rather than a single subroutine (if I am wrong, then it would be very thoughtful to share that code!). With regards to the inclusion of winds...I wouldn't bet for that.

Hope that it helps.

Ruben.

thanks a lot for your answer !

Unfortunately I have not the knowledge to modify the code of artemis to take the current in account. This should be a very hard job ! The only way for me is to test it in a basin.
