Abstract
Sediment barrier for reducing the erosive energy of water flow through on a watercourse such as a surface, a rill or similar channel, and for increasing the deposition of sediments therein. The sediment barrier includes a plurality of individual strands emanating outwardly from a foundation common to all the strands, and forming a structured flow-permeable array having a certain shape to extend outwardly from the watercourse on which the barrier is placed. The individual strands preferably are crimped or otherwise distorted in external configuration so as to provide fiber-to-fiber cohesion which helps maintain the overall array of the barrier. The sediment barrier is anchored in place on a surface or within a rill or gully, so as to maintain the strands in upright relation to the watercourse.
