DEFINITION

Classification: 405/21

Wave to flow dissipation:

(under subclass 15) Method or apparatus wherein the kinetic energy of the water is controlled or selectively released or redirected.

(1) Note. In order to be classified as an original in this and indented subclasses, patents relating to a vertical wall at the water-land interface (e.g., sea wall) must claim a step or means for wave or flow dissipation. In the absence of wave or flow dissipating structure a patent claiming an earth-retaining sea wall or similar structure will be placed in subclass 262 or subclasses 284+.
