Structure intended for cancelling an incident swell or a similar hydrodynamic phenomenon, characterised in that it is composed of a series of thin screens (1, 2, 3, 4) parallel to one another and not parallel to the direction of the said incident swell (H), the height of these screens being at a vertical distance from the bottom (F) which allows the water to circulate, whilst at the same time generating a considerable loss of head in this flow. <IMAGE>
