The Canoe-fishway is a rather new concept of fishways. A lot of thin and elastic elements were used to built it – it works like vegetation. The big advantage of this type of construction is that it may be used by kayaks and canoes to pass an obstruction in the river without danger of destroy it. The velocity profile is divide for two part: lower velocity on the brushes level and higher velocity above the brushes. Energy dissipation within this type of fishways is very effective. The large number of bristles produce many small vortex which initiate energy consumption by the velocity of water.
