The floating pockets of the barrier, the openings of which are downwardly disposed, are given their shape and kept in shape by masses of a material which is lighter than water. These masses preferably consist of a cellular material which is watertight and minimally compressible, of inflated bladders, or of air blown into the pockets. In a preferred embodiment in which the pockets are given shape by the masses, air enters the shaped pockets and is trapped therein to effect flotation of the barrier, and provisions are made for accommodating retention of the barrier at the surface of the water, even in the event that water fills the pockets, since the masses then act to effect the flotation of the barrier. | |
