Two waves. One pump station.
A standing-wave machine that catches the water leaving the first wave and stands a second one up in it. Same lift, same water — twice the surfers.
The idea
Most wave pools throw half the energy away.
A sheet-flow standing wave works by pumping water up and letting it run down a ramp into slower water. The collision holds a wave in one place. It is a good trick, and it is expensive, because every litre has to be lifted before it can be surfed. At the bottom of the ride that water is still moving — and in a conventional pool the momentum is simply thrown back into the reservoir.
UpSurfDown puts a second wave generator in the backflow. A deflector turns the outflow of the first wave and feeds it, still carrying its residual head, into a second ramp set lower down. The capacity of the site doubles. The pump station does not.
Longitudinal section 1:200 — Werkstatt Wien Wave 1 sits at +2.70 m. Wave 2 sits at ±0.00 m. Gravity does the rest.
The rest of it
Four ways in.
