by E .. P .. D.. Mansard
In the last fifteen years the techniques of wave generation 'have advanced to a great extent that it is row possible to exercise controls, on parameters such as wave grouping, wave asymmetries. etc .. , during the
simulation process.. This paper describes some of these techniques that
were developed at the National Research Council of Canada, towards a
better understanding of Nature and its reproduction.. Emphasis is given
to the non-linearities associated with shallow water waves and the difficulties encountered in depth limited situations due to complex shoaling mechanism.
Au cours des 15 derni~res ann~es les m~thodes de 9~n~ration des vagues
ant tellement progress~ qu'il est maintenant possbile de contrOler des
param~tres comme Ie groupement des vagues, les asym~tries des vagues,
etc .. , pendant Ie processus de simulation.. Cette ~tude d~crit certaines
des m~thodes mises au point au Conseil national de recherches du Canada
pour une meilleure compr~hension de la nature et sa reproduction plus
fid~le" L'emphase a ~t~ plac~e sur les non-lin~arit~s associ~es aux
vagues en eaux peu profondes et sur les difficult~s que pose Ie complexe
m~canisme de la diminution des profondeurs en situations de profondeur restreinte"
