Maximum outer-bank velocity reduction for vane-dike fields installed in channel bends
Hydraulic conditions associated with channel bends in meandering rivers include secondary, helical currents, mass shift of flow to the outside of the bend, and increased erosion along the outer streambank. Such outer-bank erosion may result in undesired plan-form migration of the stream course, placing valuable land holdings or infrastructure in jeopardy. A type of instream transverse rock structure, the vane dike, has been installed in field scenarios to mitigate problematic hydraulics associated with migrating river bends. Flows around vanes and similar structures have been modeled extensively ...
