This sculpture symbolises the confluence of the four rivers at Hertford - the Lea, the Rib, the Mimran and the Beane. It was commissioned by Hertford Civic Society for the town centre.
This is one of a series of water sculptures predicated upon the hydrostatic law that water pressure is determined by its 'head', the distance from surface to outlet. When a number of outlets are placed at regular descending positions from a common head, each spout takes up a different curve, determined by its particular pressure.
This principle has been applied to Confluence by arranging four rows of jets which converge in the centre of the sculpture, the water from the nozzles being collected within a bronze receptacle which diffuses the pressure and directs the water down in a foaming cascade.
