Definitions

  • Wave pool construction and operation can also be costly. Water parks can require a minimum of 10-30 acres, extensive infrastructure, staffing, and considerable energy consumption for the generation of waves. Wave pools that are capable of producing large, surfing waves can be even more expensive. The expense of generating surfing waves may be calculated on a cost per wave basis. Some facilities charge surfers based on their expected revenue per wave.

  • the wave pool includes a first deep area adjacent the end of the wave pool having the wave generating device. It is followed by a first artificial reef that creates a first shallow area that causes a swell created by the wave generating device to become a first surf-able wave. This is followed by a second deep area that causes the first surf-able wave to revert to a swell. A second artificial reef creates a second shallow area causing the swell to become a second surf-able wave. A basin and swash area follows the second artificial reef for dissipating the remaining energy of the second surf-able wave.
  • Another embodiment discloses a deep center channel that extends the length of the wave pool to the swash area in which no surf-able waves are formed.
  • the deep center channel acts as a buffer zone that separates the first artificial reef from the second artificial reef and the third artificial reef from the fourth artificial reef thereby allowing separate wave segments to be surfed by a plurality of surfers.

  • the bottom topography of a body of water is one of the factors in how a wave breaks.
  • Most wave pools include some form of incline and a simulated beach opposite the wave generator.
  • Natural beaches have inclines that range from steep (reflective of waves) to gradual (dissipative of wave energy).
  • Wave pool beach inclines support or foster the creation of surf and then provide a dissipative end or swash zone for the beach. That is, these pools often have a bottom incline that culminates in a gradually inclined beach area. Prior to the swash zone, the incline is typically steeper to support the conversion of swells into the peaked waves of surf.

  • reef breaking surf is made up of waves that break over a solid base, such as a rock or coral reef.

  • Opposite wave generator 5 is beach area 7.
  • wave pool 1 may include a more gradual or dissipative increase in elevation so that the depth becomes increasingly shallow over the run of a wave, depending on the type of wave desired and the energy required.

  • artificial reef 61 and deep area 3B are long enough such that surfers located at sports A, B, C, and D will slow after having ridden their first wave. After the swell passes through deep area 3B it encounters artificial reef 62. Surfers located at spots E, F, G, and H may then ride the wave.

Alternatively, edge shallows 51 and 52 may continue for the length of the pool, such that surfers located at spots A and D might continue surfing the whole length of wave pool 1. As noted above, the swell in deep side channels 41-44 will precede the wave created by edge shallows 51 and 52. Thus, surfers beginning at spots A or D riding a wave in the traditional backhand approach (i.e., back to the wave) would have their surfboards pointed inwardly, towards the deep side channels.

Abstract

L'invention concerne une piscine à vagues permettant de créer de multiples vagues sur lesquelles on peut surfer quand un dispositif générateur de vagues exerce une force sur l'eau dans une première extrémité de la piscine à vagues. La piscine à vagues comprend une première zone profonde adjacente à l'extrémité de la piscine à vagues ayant le dispositif générateur de vagues. Elle est suivie d'un premier récif artificiel qui crée une première zone de haut-fond qui amène une houle créée par le dispositif générateur de vagues à devenir une première vague sur laquelle on peut surfer. Ceci est suivi d'une deuxième zone profonde qui amène la première vague sur laquelle on peut surfer à redevenir une houle. Un deuxième récif artificiel crée une deuxième zone de haut-fond qui amène la houle à devenir une deuxième vague sur laquelle on peut surfer. Une zone de bassin et de déferlement suit le deuxième récif artificiel pour dissiper l'énergie restante de la deuxième vague sur laquelle on peut surfer. Une éventuelle série de hauts-fonds latéraux peut sensiblement s'étendre sur toute la longueur de la piscine à vagues pour créer une vague en rouleau sur laquelle on peut surfer de chaque côté de la piscine à vagues.
