This is a small operational model of a
large waterwall fountain installation. The platform on which the wall is
supported is intended to be shallow to facilitate waves rebounding from the
edges of the platform as the fountain operates. The waterwall is curved in a
slight arc and has a linear weir in proximity to the top of the concave side of
the wall. Wall thickness is purposely kept narrow in relation to the width and
height of the wall; this gives the visual impression of a thin arc without
bringing attention to the manner in which water is delivered to the weir.
Output of the wall is controlled by a
microcontroller-based drive. Control electronics can be supplied to make the
fountain responsive to an environmental soundscape; alternatively, the fountain
can respond to viewer presence and/or dynamic proximity of viewers to the wall
(i.e. by employing ultrasonic ranging). In its simplest form, the fountain can
run completely under program control.
The fountain is preferably fabricated
in stainless steel.
Novelly, the curvature of the wall allows
a variety of flows to be generated without water splashing or dropping from its
