THE PARASITE PHENOMENON IN A TCAVE CANAL

[摘要] A detailed study of wave profiles undertaken by our laboratory and making use of a wave recording apparatus, which is the subject of another paper, has drawn our attention to a parasite phenomenon. In certain conditions this phenomenon has a period twice that of the principal movement. The phenomenon appears only over a certain range of periods and has been shown to be the result of a transversal clapotis. The appearance of a transversal clapotis in wave canals is not rare and in practice it is eliminated by placing vertical guides parallel to the longitudinal axis of the canal. We have succeeded in eliminating the transversal clapotis reasonably well, by the use of wave filters. But a progressive phenomenon, with the period of the clapotis, has remained and it has been possible to analyse it.
