Flow-Responsive, Self-Adjusting Sediment Control Wattle

摘要

A sediment control device for attachment to a surface with liquid flow moving in a flow direction includes a base fastenable to the surface, the base including a trailing portion, a central portion adjacent the trailing portion, and a distal portion adjacent the central portion; a first core located at the central portion; a second core located at the distal portion; a fastening element for fastening the base to the surface with the trailing portion in a downstream location and the distal portion in an upstream location relative to the flow direction, the fastening element being vertically aligned with the first core; and the base movable from a first position in which the second core is generally horizontally adjacent the first core along the surface to a second position in which the second core is generally vertically raised relative to the first core and the surface.
