Urban surf systems, often found in wave pools, generate waves through a mechanical process. Inside the wave-generating structure, a series of pistons (typically more than 40) move in a coordinated sequence within the water. This sequential movement mimics the action of a shark's tail. The key lies in precisely controlling the push and timing of each individual piston. By adjusting these parameters, different types of waves can be created. These generated waves then break on a specially designed bottom contour within the pool, creating the surfable wave.
Here's a breakdown:
- Pistons: A row of individually controlled pistons are submerged in water.
- Sequential Movement: These pistons don't move randomly. They are programmed to move in a specific sequence.
- Wave Generation: The coordinated pushing of the pistons generates a wave that travels down the pool.
- Wave Shaping: The shape and size of the wave are determined by the precise timing and force of the pistons' movement. Different piston patterns create different wave types (e.g., barrels, reform waves).
- Bottom Contour: The pool's bottom is carefully shaped to allow the generated wave to break in a surfable manner.
In essence, urban surf uses carefully orchestrated mechanical motion to simulate ocean waves in a controlled environment.
