Abstract
Abstract There is disclosed an elongate, impervious barrier which is flexible intermediate its ends and has upper and lower faces which converge forwardly to intersect on its front side. Buoyant means is carried by the barrier to normally maintain it in a generally upright position within a body of water and with the intersection of the upper and lower faces below a lighter phase thereof.
