ABSTRACT:
A connecting channel arrangement between two levels or planes of water of different vertical height. A channel connecting the two levels is partially obstructed by a number of flexible members which constitute obstacles to the free flow of the water in order to obtain a significant reduction of the rate of flow and of the flow velocity, while these flexible members are able nonetheless to deflect out of the way of the passage of floating devices such as boats and debris. These flexible members each have one end connected to the bed of the channel and extend through the water in the channel in a direction transverse to the flow direction. Preferred embodiments of the flexible members are constructed as hollow rubber tubes which are connected to a compressed fluid supply for controlling their flexibility.
