At many channel branches, harbor entrances, or other flow bifurcations, eddy currents form due to flow depth and velocity gradients. Several significant problems can result when an eddy current forms in a navigation route: (a) the eddy creates a quiescent region and its associated currents can trap and deposit a mound of material, shoaling the channel; (b) navigation can become more difficult due to the toroidal current pattern in the eddy; and (c) the presence of the eddy can promote water/sediment load mixing with greater adjacent velocities that carry sediment farther, extending the shoal along the channel. A new flow training structure, the current deflector wall (CDW), has successfully mitigated these navigation and maintenance problems at a major world port. This report describes the design, implementation, and effectiveness of the prototype COW installation at the Port of Hamburg, Germany.
