Abstract

A flow-training structure for use in rivers and streams to minimize bank erosion, and to control bed degradation and aggradation. The structure consists of single vanes or arrays of vanes of a particular double-curved design. The vanes are installed in the river bed in designed arrays to produce changes in the local directions of the near-bed velocity, without changing the sediment-transport or flow-conveyance capacities of the channel.
