Abstract:
An apparatus for producing an artificial waterfall, said apparatus comprising;an elongate chambered body having a length and opposite ends and defining a water inlet port intermediate of its length, said body defining a water discharge nozzle slot extending along said length and from which water issues substantially horizontally as a generally horizontally-flowing sheet; said body internally defining a first elongate chamber extending along said length and into which said water inlet port opens intermediate of and generally perpendicularly to the length of said first chamber, and a wall portion disposed in confrontation to said water inlet port and being disposed generally perpendicular to and curving with respect to a perpendicular to the water flow entering via said water inlet port so as to create a pair of oppositely-extending recirculation-current water flows each extending substantially helically from said inlet port toward a respective one of said opposite ends, andsaid body further having an elongate foraminous wall portion bounding said first chamber and through which water flows therefrom to a second chamber which also extends along said length, said second chamber communicating water flow to said water discharge nozzle slot.
