Sediment Management with Submerged Vanes. II: Applications

Abstract

The theory of submerged vanes described in the companion paper is tested with laboratory and field data. The laboratory data are from experiments in curved, and straight, recirculating sediment flumes. The field data are from river bends in which, prior to installation of vanes, the banks were eroding, and from a straightened bridge waterway in which sediment deposits were causing a change of channel alignment, bank erosion, and undermining of the bridge abutment. All data support the theory, and they suggest that the vane technique is a viable alternative to traditional techniques. The design procedure is described and illustrated with numerical examples, and vane material and typical vane layouts are discussed. Layouts are presented for protection of stream banks against erosion and for amelioration of shoaling problems in navigation channels, at water intakes, in bridge crossings, at river confluences, and at diversions.
