Definitions

  • a third corollary disadvantage related to the formation of rip currents and wave reflections is the resultant reduction in the pool's productive asset value that can result from having to reduce the frequency of the waves in an attempt to reduce these unwanted movements and characteristics.
  • it is usually desirable to increase the frequency of wave generation to increase the number of riders that can participate per hour (with a corresponding increase in revenue per hour using the same asset base) the downside to doing so is that the occurrence of rip currents and wave reflections can thereby increase.
  • the inventors sought to develop some theories regarding how waves might be dampened by a perforated raised floor by testing different floors and configurations with different wave conditions. They tested a number of different configurations including floors with different porosities, slopes and depths, as well as waves having different heights, and shapes, etc., and through this process, they were able to make some rough estimates regarding the preferred levels for the specific pool configurations and wave characteristics they observed.

  • Figure 24 shows the first step of the method of making the monolithic sheet of composite members, wherein the first step comprises applying an adhesive onto a sheet of foam and adhering multiple rigid bars onto the sheet of foam;

  • Figure 33A shows the jig that is used to help orient and position the composite members into sheets, such that they are positioned in a substantially parallel manner with a predetermined space between each one— note that the rigid bar is facing up and the padded surface is facing down while the composite members are positioned on the jig;

This is because if raised floor 20 is deeper than the break depth the waves would not develop nor break properly onto wave dampening chamber 19. And because raised floor 20 is preferably extended substantially horizontally from inclined section 13 toward end wall 12, the top 17 of inclined section 13 should be at the same depth as raised floor 20, wherein they are both preferably located at the break depth.
  • the preferred depth ratio between raised floor 20 and chamber 19, as designated by ⁇ dn 00 dumber is preferably 0.33 (1 /3).

Abstract

Une piscine à vagues permettant de produire des vagues comporte une première partie formation de vagues présentant une section inclinée, et une seconde partie d'atténuation des vagues comportant un plancher surélevé au-dessus d'un plancher de chambre inférieure, le plancher surélevé comportant de préférence de multiples ouvertures formées dans celui-ci et présentant une porosité prédéterminée (Y) dans la plage de 0 < γ ≤ 0,5, de sorte qu'à mesure que les vagues se déplacent d'un côté à l'autre de la chambre d'atténuation des vagues, une couche limite de remous et de turbulences d'amortissement sont générés au-dessus et au-dessous du plancher surélevé, ce qui entraîne un écoulement d'eau vers le haut et vers le bas à travers les ouvertures et contribue à atténuer les vagues; et le plancher surélevé comprend de préférence un système de drainage à grille rembourrée, constitué de multiples éléments allongés parallèles formés au moyen de barres rigides sur un côté desquelles de la mousse est collée, et qui sont encapsulés par une couche imperméable à l'eau.
