MOBILE AND TRANSPORTABLE DEVICE FOR THE PROTECTION OF COASTAL AREAS AGAINST STORM CONSEQUENCES AND THE PROLIFERATION OF GREEN ALGAE

摘要

The present invention relates to a mobile and transportable device for protecting coastal areas against the consequences of storms and the proliferation of green algae, composed of four independent and co-operating main elements: e) A fishing net, preferably of the type of ocean tuna seine (1). f) A set of floating units (2) for maintaining said fishing net (1) at the surface. g) A set of connecting element (3) for holding said fishing net (1) attached to the seabed. h) A set of submerged dead bodies (4) for locally holding said fishing net (1) in position. First, the invention is directly inspired by the protective effect of coral reefs that protect coastal areas by preventing storms and significantly reducing the impact of cyclones. However, it has the advantage of being flexible and resistant compared to hard and fragile coral reefs. Second, it significantly limits the proliferation of green algae by allowing them to settle on the device during the winter period. Withdrawn at the beginning of the summer period, the said algae which could not develop to reach their adult size disappear then by drying and without fermentation because of too small sizes. According to the preferred embodiment of the invention, the ocean tuna seine-type fishing net (1) is spread over the sea surface, maintained in this position by means of floating elements (2) and connected locally to the sea surface. means of connecting elements (3) to immersed dead bodies (4). (See FIG 1).
