Abstract:
An open chamber of predetermined size and shape is positioned within a pool bed so as to contain telescopic modules which occupy the chamber area. Each of the telescopic modules is independently extended and retracted in length by increase or decrease of the volume of water contained within a bellows, establishing in selected telescopic modules a specific reef size, shape, and orientation. When kinetic-energy within the water passes over the predetermined shape, size, and orientation of the reef, a wave is generated having specific features resulting from the properties of the specific reef configuration.

Description:
FIELD OF THE INVENTION 
     The present invention relates to artificial water wave generation in natural and man-made bodies of water for surfing. 
     BACKGROUND OF THE INVENTION 
     Water waves occur in natural and artificial bathymetry. Wind, water current, and topographical ocean bed and pool floor features, each and in combination thereof can cause the generation of waves. Relying on naturally occurring conditions and limitations in geographic location can greatly diminish availability, predictability, frequency and quality of waves sought in the art and sport of board surfing. When the topography of an ocean bed or pool floor includes the presence of a reef, the kinetic energy of a wave passing over the reef can be greatly affected by the presence of the reef. The magnitude of the affect is dependent upon several factors, such as the depth of the water, slope at the approach to a beach, wave period, wave amplitude and direction of force in the kinetic energy of the wave with respect to the orientation of the reef. In simple terms, when the bottom-most depth of wave energy comes in contact with the incline approach to a beach, or to a much greater affect, the approach to a reef, the bottom-most depth of wave energy (trough) becomes increasingly retarded. The top-most height of the wave energy (crest) continues to advance at a constant rate. Eventually, gravity overcomes the unsupported wave crest, and the wave breaks and peels. Attempts have been made to enhance wave size, shape and direction of peel to best meet the demands of the surfer. Artificial reefs have been successfully constructed thereby enhancing the waves generated by wind, topographic features and bathymetry. Such reefs are constructed using mathematical, and scaled-down engineering models under conditions of several variables. Consequently, upon full-scale construction, the anticipated performance of the reef does not perform exactly as intended. Scale working models are utilized in testing reef size and configuration with promising results. However, when full-scale inventions are constructed at extensive cost, the performance is less than expected because of fluid dynamic inconsistencies in the physics of bringing models to full-scale size. The term applied to this phenomenon is “natural similitude”. Most man-made reefs and all natural reefs are static and thereby exist in specific configuration resulting in drastically limited variation in wave generation. Rigid reef inventions that provide for variation in orientation and alignment with respect to a pool bed provide some variation in wave type, however they do not provide more than one direction of peel, they do not provide variation in the rate of peel of waves generated, they do not provide for wave life before decay, nor do they provide for a near infinite combination or plurality of simultaneous waves. 
     In other prior art wave forming devices, attempts have been made to enhance wave size, wave shape, wave duration, and wave direction of peel by placing an adjustable weir onto the bed of the body of water, normal to the direction of flow. The specific incline to the weir and decline to the bed is basically a reef. The elevation of the weir with respect to the elevation of the bed is varied by means of hydraulic piston cylinders, pivot points or combination of both. Other wave enhancing devices include rigid reef configurations that are suspended above the bed of the body of water at predetermined distances and predetermined angle of inclination with respect to the direction of water flow, thereby attempting to establish adjustment of the reef in juxtaposition to the bed, water flow, and water depth. Cables and or hydraulic pistons are interconnected, anchored onto the bed and onto the distal surface of the reef. In other prior art wave forming devices, a wave is actually simulated in the water itself, rather than being defined by a surface over which a thin sheet of water flows. U.S. Pat. No. 6,019,547 of Hill, Feb. 1, 2000 describes a wave forming apparatus which attempts to simulate natural antidune formations in order to create waves. A water-shaping airfoil disposed within a flume containing a flow of water, and a wave-forming ramp is positioned downstream of the airfoil structure. In other prior art arrangements, such as U.S. Pat. No. 6,928,670 B2, of Lochtefeld et al., Aug. 16, 2005 describes a moving reef wave generator that travels along the surface of a body of water, and preferably in the middle thereof, wherein the wave generator can create both primary and secondary wave that travel toward the shore. The primary waves are intended to allow surfing maneuvers to be performed in a relatively deep water environment. The secondary waves can break, wherein by modifying the shoreline&#39;s slope and curvature, and providing undulating peninsulas and cove areas, various multiple wave formations and effects can be created. 
     In the prior art of McFarland, U.S. Pat. No. 6,932,541 B2, Aug. 23, 2005, a plurality of a semi-rigid reef, referred to a a weir, is interconnected in cantilever onto the bed of a pool of water at the upstream, leading end having a predetermined abrupt incline and gentle downward slope at the downstream end. A secondary passageway extends through the bed form, with a first end adjacent the trailing end of the bed form, and a second end in the bed form upstream of the first end, thereby creating a pocket between the bed and underside of the Hydraulic rams independently control the lift of each cantilevered reef. A grating is provided between adjacent reefs to prevent inadvertent entry between the reefs and water return channels beneath. However, the grating provides the risk of collision with an occupant in the even of a fall in riding a wave. Furthermore, although the invention provides for some variation in wave size, it does not provide for variation in wave peel direction, wave type, wave size, or wave orientation. The flow of water current between wave cycles could create serious rip tides between and beneath the suspended reefs. In the prior art of Hill, U.S. Pat. No. 6,019,547, Feb. 1, 2000 an airfoil chute or pool and an aerofoil structure shapes the flow of water generated by the chute and variable ramp. Although there is some variation in wave shape of the surfable wave, the rigid surface of both airfoil and ramp limits the variation in reef configuration and thusly wave type, size, and peel. Furthermore, the suspended configuration of the airfoil presents a safety hazard, causing an occupant to become lodged between the airfoil and pool bed. In U.S. Pat. No. 6,928,670 B2, of Lochtefeld et al., Aug. 16, 2005, the moving reef traverses along the length of a pool near the surface of the water, pulled along a track fastened onto a pool bed. This moving device can be inadvertently impacted by the surfer resulting in serious injury. Even though the device moves, the rigid configuration greatly reduces the variation of wave generation types and direction of wave peel. To enhance wave size, the device must move at a greater rate of speed, thereby increasing the risk of bodily injury if impacted by the surfer. The mechanical means of connecting the moving reef device to the track system creates further risk of injury at the juncture of the moving reef&#39;s stem and tracking slot located between the track-mounted trolley and interconnecting moving reef. In testing a wave-generating invention at a scaled-down size, the outcome in full-scale engineering can result in failure. A full-scale production reef was constructed having a buoyant, rigid reef subtended by cables subtended from the distal face of the reef and anchored to a reinforced-concrete pool-bed. When tested, the wave energy generated an uplifting force sufficient enough to separate the attachment of the reef from the pool-bed, virtually pulling the anchored cables from the pool bed, causing millions of dollars in damage and severe delays in the project. 
     In the prior art of Fuller et al., U.S. Pat. No. 5,219,315, a simulator for water rides comprises a theater projection and sound that simulates motion for audience within a raft contained within the confines of a pool completely surrounded with walls. Adding to the simulation is a system for providing water spray, and actuators that provide a “rocking motion” to the raft when the actuators are operating. As such, relative to the earth, there is no actual displacement of the raft and the occupants referred to as the “audience” within the raft. The raft does not traverse any distance with respect to the raft&#39;s position to the earth . . . the raft merely experiences the “rocking” motion. In Fuller&#39;s invention, the actuators are either connected directly to the raft or the actuators are connected to a flexible plate which transmits agitation to the water contained within the pool which in turn, “rocks” the raft. Regardless of either configuration, in order for any rocking motion to be imposed to the raft, the actuators must be in motion since the actuators generate the “rocking” motion. When the embodiment utilizes the flexible plate to agitate the water, flexibility can only occur in one horizontal axis at a time because the plate cannot be stretched or compressed. This physical limitation of the plate limits the “rocking” motion to either side-to-side with respect to the raft, or front-to-back with respect to the raft. When the embodiment utilizes having the actuators connected directly to the raft, the rocking motion of the raft experiences can be more random with respect to side-to-side and/or front-to-back. However, in this particular embodiment whereby the actuators are connected directly to the raft, there is no need for water within the pool, further demonstrating the fact that the invention is merely a simulator, since the raft “rocks” without having the presence of water to both “rock” and support the raft in the stationary, “rocking” position.

     SUMMARY OF THE INVENTION 
     In accordance with the present invention, there is provided a reef that is comprised of a plurality of a telescopic-module that is grouped in a plurality of interconnected clusters thereby establishing contiguous three-dimensional variations for a reef. Each cluster is configured geometrically, comprised with a primary-module which is center-positioned and is interconnected with a surrounding plurality of a secondary-module. The primary-module acting as a hub, extends downwardly and beyond the distal end of the secondary-module thereby supporting the secondary-module. The geometric arrangement is much like pedals of a flower, whereby the secondary-telescopic-module represent the pedals and the primary-telescopic-module represents the pod, with a stem extending downwardly and beyond the distal end of the secondary-telescopic-module. The domain of the variable reef is established so as to provide the desired characteristics of specific waves desired. As a means of establishing the domain of the plurality of the telescopic-module within the confines of a pool floor, a chamber is provided. The chamber, communicating with a pool floor, is configured to a predetermined size, shape, and depth below the elevation of the pool floor, thereby acting as a yoke to restrict lateral movement of the plurality of the telescopic-module clusters when acted upon by kinetic-energy of water passing above the entire domain of the reef. The predetermined depth of the chamber dependent upon the predetermined maximum reef height required above the elevation of the communicating pool floor plane so as to achieve specific wave height characteristics. As such, the range of length of the telescopic-module extension from a full-retracted attitude coplanar with the pool floor to a full-extended attitude dictates the chamber depth beneath the pool floor. Furthermore, a minimal depth of the chamber is defined by the a predetermined distance below the distal end of the plurality of the secondary-module so as to permit technicians to traverse between the module clusters for the purpose of construction and maintenance of the reef system. This provision omits “down-time” in the event of repairs to the telescopic-modules. The domain of the telescopic-module provides for a variety of reef shape, size, and orientation within the confines of the chamber, thereby providing a means of generating a variety of wave shape, size, orientation, direction of peel, and duration of peel. Each of the telescopic-module is controlled independently so as to vary in extension independently. When completely retracted, the telescopic-module height is aligned within the same plane as the circumventing pool floor thereby establishing a condition as if no reef exists. When a plurality of predetermined telescopic-module is selected and activated to “telescope” or extend upwardly, each at a progressive predetermined height, the telescopic-module group acts in totality to create a unique, predetermined reef thereto creating a specific wave generation. Extension and retraction of each telescopic-module is accomplished, and controlled by a predetermined volume of water that is contained within a bellow interconnected within the confines of the telescopic-module. When the volume of water contained within the bellow is increased, the bellow elastically extends, thereby causing the telescoping-upper-body to elevate to a predetermined height above the plane of the encompassing pool bed. Conversely, when the volume of water contained within the bellow is depleted, the bellow elastically retracts, thereby causing the telescoping-upper-body to descend to a predetermined height above or at the plane of the encompassing pool bed. Once the desired attitude of each the telescopic-module is attained, no further displacement of motion of the telescopic-module takes place until a variation in wave performance is desired. As such, the telescopic-module motion, extension or retraction, does not create the wave energy. The wave energy is created upstream from the reef and the configuration of the reef causes the wave energy to generate specific variations in waves when the energy passes over the specific reef. These variations in reef shape, size, and orientation provide for creating various wave types, size, direction of peel, duration of peel, single and multiple simultaneous wave generation. In accordance with the direction of a kinetic-energy introduced to the water within the pool, a diagonal-left reef extends down-stream towards a beach traversing from right to left, thereby causing the kinetic-energy over-passing the diagonal-left-reef to generate a wave which will peel or break from right to left along a plateau permit technicians to traverse between said modules for the purpose of construction and maintenance of the reef system. This provision omits “down-time” in the event of repairs to the telescopic-modules. The domain of the telescopic-module provides a variety of reef shape, size, and orientation within the confines of the chamber, thereby providing a means of generating a variety of wave shape, size, orientation, direction of peel, and duration of peel. Each of the telescopic-module is controlled independently so as to vary in height independently. When completely contracted, the telescopic-module height is aligned within the same plane as the circumventing pool floor thereby establishing a condition as if no reef exists. When a plurality of predetermined telescopic-module is selected and activated to “telescope” or extend upwardly, each at a progressive predetermined height, the telescopic-module group acts in totality to create a unique, predetermined reef thereto creating a specific wave generation. In either scenario, the contiguous array of telescopic-modules to each other and to the confines of the chamber thereto communicating to the pool floor, prevents the possibility of a swimmer or surfer from inadvertently becoming trapped between the module clusters. Extension and retraction of each telescopic-module is accomplished, and controlled by a predetermined volume of water that is contained within a bellow interconnected within the confines of the telescopic-module. When the volume of water contained within the bellow is increased, the bellow elastically extends, thereby causing the telescoping-upper-body to elevate to a predetermined height above the plane of the encompassing pool bed. Conversely, when the volume of water contained within the bellow is depleted, the bellow elastically retracts, thereby causing the telescoping-upper-body to descend to a predetermined height above or at the plane of the encompassing pool bed. Once the desired attitude of each the telescopic-module is attained, no further displacement of motion of the telescopic-module takes place until a variation in wave performance is desired. As such, the telescopic-module motion, extension or retraction, does not create the wave energy. The wave energy is created upstream from the reef and the configuration of the reef causes the wave energy to generate specific variations in waves when the energy passes over the specific reef. These variations in reef shape, size, and orientation provide for creating various wave types, size, direction of peel, duration of peel, single and multiple simultaneous wave generation. In accordance with the direction of a kinetic-energy introduced to the water within the pool, a diagonal-left reef extends down-stream towards a beach traversing from right to left, thereby causing the kinetic-energy over-passing the diagonal-left-reef to generate a wave which will peel or break from right to left along a plateau of the diagonal-left-reef. Conversely, in accordance with the direction of the kinetic-energy introduced to the water within the pool bed, a diagonal-right-reef extends down-stream towards a beach traversing from the left to right, thereby causing the kinetic-energy over-passing the diagonal-right-reef-reef to generate the wave which will peel from left to right along the plateau of the diagonal-right-reef. When a reef is configured in a vee shape with the vertex located at or near the centerline of the pool and upstream, convex to the direction of the kinetic-energy, the wave generated peels from the vertex in both directions along the plateau of the vee-reef. The desired configuration, size, and orientation of any reef type is determined by means of testing at full-scale for the purpose of creating the optimum wave performance. Upon testing for each desired specific wave type, size, and orientation, the volume of water contained within each individual module is programmed into a computerized system. This full-scale testing and evaluation is therefore executed in a condition termed “natural similitude”. As such, the programmed settings can be adjusted for subsequent testing of wave performance for the purpose of enhancing the wave characteristics desired. Furthermore, the domain of the reef and thusly the size and shape of the chamber is established with a predetermined size and shape omitting areas within the confines of the pool floor where the variable reef would prove ineffective. This measure of calculating the domain size and shape provides considerable economies of scale in cost savings. The cylindrical longitudinal shape of each set of three of the tangential adjoining telescopic-module provides a vertical equilateral concave triangular void. The void provides for circulation of water contained within the pool to pass downwardly through each of the void into the chamber and circulate from the chamber to a pumping filtration and purification system (not shown) located outside the confines of the pool, thereto returning filtered and purified water to the pool. Furthermore, the void provides for light to pass upwardly from a light source within the confines of the chamber to the pool area defined by the domain of the reef.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       FIG. 1  is a side view of a telescopic-module  10  partially extended. As shown by a displacement  67  of a telescoping-upper-body  12 , the telescopic-module  10  extension varies from a completely retracted-length  28  (show in  FIG. 3 ) to a completely extended-length  30  (shown in  FIG. 2 ). Along a centerline  58 , the proximal end of the telescopic-module  10  is comprised of a hemispherical dome  16  made of an elastomeric material such as silicone so as to enhance compressibility if inadvertently impacted by a swimmer or surfer. Communicating with the dome  16  is the telescoping-upper-body  12 . Longitudinally inserted within the telescoping-upper-body  12  is a stationary-lower-body  14  of predetermined outside diameter so as to provide slidability of the telescoping-upper-body  12  without causing lateral or concentric misalignment. The stationary-lower-body  14  is circumferentially fitted with a collar  18  of outside diameter equal to the outside diameter of the telescoping-upper-body  12 . The collar  18  provides for proper parallel alignment when interconnected with one or more of the telescopic-module  10 . 
       FIG. 2  is a longitudinal cross sectional view of the telescopic-module  10  in the full extended-length  30  showing a maximum-displacement  69 . The dome  16  of the telescopic-module  10  is elastically captured onto a proximal-retainer  22 . The proximal-retainer  22  is insertibly fitted into the proximal end of the telescoping-upper body  12  and is attached by means of a first-fastener  40 . The proximal end of a bellow  20  is elastically fitted onto the proximal-retainer  22  and secured by means of a first-clamp  38 . The proximal-retainer  22  also provides for attachment of a air-bleeder-valve  54  which is equipped with a air-bleeder-port  56  for the purpose of removing air trapped from within the confines of the invention. The distal end of the bellow  20  is elastically fitted onto a distal-retainer  64  and secured by means of a second-clamp  39 . The distal-retainer  64  is insertably fitted into the distal end of the stationary-lower-body  14 . During the initial start-up of the invention or at time of repair, the telescopic-module  10  contains air trapped within the confines of a supply-tube  36 , a inlet-pipe  32 , a bellow  20 , and a cavity  50  of the dome  16 . The property of air being compressible, it must be removed from within the confines of the supply-tube  36 , the inlet-pipe  32 , the bellow  20 , and the dome  16 , and displaced by water. The volume of water to be contained within a hollow  21  of the bellow  20  varies depending upon the retraction or extension in length of the bellow  20 . Air trapped within the supply-tube  36 , the inlet-pipe  32 , and bellow  20  is evacuated through a orifice  26  of the air-bleeder-valve  54  and is released into the cavity  50  of the dome  16 . The air within the dome  16  is expelled into the confines of the telescoping-upper-body by means of a plurality of a first-air-bleeder-port  56  located through the horizontal surface of the proximal-retainer  22  within the confines of the dome  16 . A second-bleeder-port  57  located at the proximal end of the telescoping-upper-body  12  and immediately below the location of the proximal-retainer  22  provides for the evacuation of air from the confines of the telescoping-upper-body, external to the invention. The cavity  50  of the dome  16  provides for collapse of the dome  16  upon inadvertent impact by a swimmer or surfer and memory of the elastic dome  16  will cause the dome  16  to return to a normal hemispherical shape. Once the volume of trapped air is expelled from within the inlet-pipe  32 , supply-tube  36 , and the bellow  20 , the first-bleeder-port  56  serves a second purpose. In the event of inadvertent impact by a swimmer or surfer, the dome  16  will collapse, causing water contained within the dome  16  to evacuate through the first-bleeder-port  56  into the confines of the telescoping-upper-body  12 . Subsequent to impact, the force of the memory of the elastic dome  16  causes the expelled water to return to the cavity  50  of the dome  16  through the first-bleeder-port  56 . As a means of reducing the risk of sand or other such debris from collecting onto the horizontal surface of the distal-retainer  64 , within the assembly of the telescoping-lower-body and said distal-retainer  64 , a plurality of a weep-hole  62  is provided through said horizontal surface. 
       FIG. 3  is a longitudinal cross sectional view (taken from  FIG. 4 ) of a cluster  82  of the telescopic-module  10  showing various lengths of extension ranging from a zero displacement  68  to a maximum-displacement  30 . The cluster  82  is comprised of a primary-module  72  and a plurality of a secondary-module  76 . Acting as a hub, the primary-module  72  is centered and surrounded geometrically by the plurality of the secondary-module  76 . All of the telescopic-module  10  are interconnected with a plurality of a second-fastener  41  at a interface  78  through a bore  80 . The second-fastener  41  is introduced through the bore  80  located so as to interconnect the distal-retainer  64 , the stationary-lower-body  14 , and the collar  18  of the adjoining telescopic-module  10 . The adjoining plurality of the cluster  82  of the telescopic-module  10  create a building-block for a contiguous variable reef-domain  87  (shown in  FIG. 8 ). The cluster  82  provides for establishing a means for having said cluster  82  pre-fabricated to enable the reef-domain  87  to be assembled with less effort and improved efficiency. The stationary-lower-body  14  of the primary-module  72  extends downwardly a substantial predetermined distance beyond the stationary-lower-body  14  of the plurality of the surrounding secondary-module  76  of the cluster  82  and communicates with a base  60  which in turn is anchored onto a chamber-floor  46  of a chamber  42  by means of a plurality of a third-fastener  43 , thereby establishing and acting as a column to support the weight and maintain position of each of the cluster  82  to resist hydrodynamic forces generated by kinetic-energy  52  in a wave  114  (shown in  FIG. 10 ) generation process. The configuration shows an independent predetermined extension of each of the telescopic-module  10  for the purpose of establishing a predetermined profile  70 . When all in the plurality of the cluster  82  are interconnected, the contiguous variable reef is established. When all of the telescopic-module  10  are postured in the retracted-position  28  within the same plane as the pool bed  124 , essentially there is no reef. When a predetermined selection of the telescopic-module  10  are extended or retracted to desired independent lengths, a specific shape, size, and oriented reef is established, thereto generating a conforming specific wave  114  (shown in  FIG. 10 ) when the water is acted upon by a kinetic-energy  52 . 
       FIG. 4  is a top schematic view of the cluster  82  of the telescopic-module  10  showing the primary-module  72 , and a plurality of the secondary-module  76 . A cluster-perimeter  96  defines the general hexagonal geometric shape generated by a plurality of the encompassing secondary-module  76 . A series of two encompassing rows of the telescopic-module  10  are shown. However, the number of concentric rows can vary from a single encompassment to two or more, thereto increasing the number of the secondary-module  76  required from six to eighteen respectively, and so forth. Each of the tangential adjoining telescopic-module  10  establish the interface  78 . The area between each of the three adjoining telescopic-module  10  create a equilateral triangular concave void  84 . The void  84  provides a conduit for water circulation from a pool  123  (shown in  FIG. 10 ) into the chamber  42 . Water is pumped from the chamber  42  to a purification and filtration system (not shown) outside the confines of the pool  123 , and is thereto circulated back to the pool  123 . Another purpose of the void  84  is to illuminate the water above the area of the reef from within the confines of the chamber  42  by providing lighting fixtures at predetermined locations at the chamber-floor  46 , directing light upwardly through the void  84  thereby creating a visual enhancement after dark. The illumination will also provide light necessary for repairs to the telescopic-module  10  from within the chamber  42 . 
       FIG. 5  is a top schematic view of the cluster  82  of the telescopic-module  10 , and the cluster-perimeter  96  of the plurality of the cluster  82  interconnected. The interface  78  is the location for interconnection of each of the telescopic-module  10 , and the adjoining cluster  82  by means of a plurality of the second-fastener  41 . Juxtaposition of each of three of the tangentially adjoining telescopic-module  10  creates the void  84  which provides for water circulation from the pool  123  communicating with the chamber  42 , and pool illumination above the reef-domain  87 . 
       FIG. 6A  is a plan view of the chamber  42  of predetermined shape, size, and location as defined by the chamber-floor  46 , within the confines of the pool floor  124 . The geometric configuration of the chamber  42 , as defined by the chamber-perimeter  86 , in lieu of a simple rectilinear perimeter, greatly reduces the number of the telescopic-module  10  by omission of areas where the reef is not required, thereto providing a cost saving. The chamber  42  is comprised of a longitudinal axis-of-symmetry  126  parallel to a kinetic-energy  52  direction for providing a reciprocal of any configuration.  FIG. 6A  is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy  52 . 
       FIG. 6B  is a plan view of the chamber  42  showing within outline a predetermined vee-reef  88  for generating a wave  114  (shown in  FIG. 10 ), having a peel  118  (shown in  FIG. 10 ) direction of the breaking wave  114 , and the kinetic-energy  52  direction. The vee-reef  88  generates the wave  114  with the peel  118  beginning at the axis-of-symmetry  126  and moving outwardly, and equidistantly in both directions as shown. The telescopic-module  10  located in the area established between the chamber-perimeter  86 , and the vee-reef  88  are dormant, and remain in the full retracted-position  28 .  FIG. 6B  is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy  52 . Chamber  42  defines the reef-domain  87 . The shape of the vee-reef  88  is not necessarily limited to be confined within the outline of  FIG. 6B  as this outline merely provides for a general configuration of the vee-reef  88 , and the wave  114  generation option. 
       FIG. 6C  is a plan view of the chamber  42  showing within outline a predetermined diagonal-left-reef  90  for generating the wave  114  (shown in  FIG. 10 ) having the peel  118  direction of the breaking wave  114 , and the kinetic-energy  52  direction. The diagonal-left-reef  90  generates the wave  114  with the peel  118  beginning at the right showing the direction of the peel  118 . Chamber  42  defines the reef-domain  87 .  FIG. 6C  is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy  52 . The shape of the diagonal-left-reef  90  is not necessarily limited to be confined within the outline of  FIG. 6C  as this outline merely provides for a general configuration of the diagonal-left-reef  90 , and the wave  114  generation option. 
       FIG. 6D  is a plan view of the chamber  42  showing within outline a specific diagonal-right-reef  92  for generating the wave  114  (shown in  FIG. 10 ) having the peel  118  direction of the breaking wave  114 , and the kinetic-energy  52  direction. The diagonal-right-reef  92  generates the wave  114  with the peel  118  beginning at the left showing the direction of the peel  118 . Chamber  42  defines the reef-domain  87 .  FIG. 6D  is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy  52 . The shape of the diagonal-right-reef  92  is not necessarily limited to be confined within the outline of  FIG. 6D  as this outline merely provides for a general configuration of the diagonal-right-reef  92 , and the wave  114  generation option. 
       FIG. 7  is a perspective view of the cluster  82  of the telescopic-module  10  showing the primary-module  72 , and a plurality of the secondary-module  76 . The collar  18  of the primary-module  72  extends downwardly communicating with the base  60  thereto communicating with the chamber-floor  46  of the chamber  42 . The base  60  is anchored onto the floor  46  by means of a plurality of the third-fastener  43 , thereby preventing uplifting dynamic force caused by the wave  114  (shown in  FIG. 10 ) generation across, and above the reef-domain  87  (shown in  FIG. 8 ). A access-opening  74  within the collar  18  of the primary-module  72  is provided in proximity to and below the distal-retainer  64  for the purpose of assembly, and attachment of the distal end of the bellow  20 , the distal-retainer  64 , the inlet-pipe  32 , the union  34 , and transmission of the supply-tube  36 . Each of the telescopic-module  10  is operated independently for establishing variation in extension of the telescopic-module  10  thereto establishing variation in reef size, shape, and orientation. 
       FIG. 8  is a plan view of the reef-domain  87  within the confines of the chamber  42  showing to full capacity, the total population of the telescopic-module  10  establishing the domain within the chamber-perimeter  86 . The diagonal-right-reef  92  is comprised of a series of three distinct planes comprising a proximal-slope  100 , a plateau  104 , and a distal-slope  102 , given in the respective sequence to the kinetic-energy  52  direction. The direction of the peel  118  is shown to begin at the left of the diagonal-right-reef  92  as the kinetic-energy advances toward a beach (not shown). One of the cluster  82  positioned within the dormant-reef  94  field is defined independently for clarity.  FIG. 8  is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy  52 . The shape of the diagonal-right-reef  92  is not necessarily limited to be confined within the outline of the diagonal-right-reef  92 , as this outline merely provides for a general configuration of the reef, and the wave  114  generation option. 
       FIG. 9  is a perspective view of the reef-domain  87  within the confines of the chamber  42  showing the predetermined diagonal-right-reef  92 , the peel  118  direction, and the kinetic-energy  52  direction. A length  106  of the diagonal-right-reef  92  is shown corresponding to a width  108  of the diagonal-right-reef  92 . A height  110  of the diagonal-right-reef  92  represents the elevation of the plateau  104  with respect to the pool-floor  124  (shown in  FIG. 10 ). The dormant-reef  94  is shown outside the delineation of the diagonal-right-reef  92  which represents the plurality of the telescopic-module  10  which remain coplanar to the pool-floor  124 . As kinetic-energy  52  passes in the general direction as shown, the kinetic-energy  52  is confined by approach to a toe  98  along the length  106  of the proximal-slope  100 , and continues to be further confined along the proximal-slope  100  to the plateau  104 , causing the wave  114  to break, and create the peel  118  before passing beyond the distal-slope  102  (shown in  FIG. 10 ). Reef size, orientation, or configuration can be modified or changed from the diagonal-right-reef  92 , the diagonal-left-reef  90 , the vee-reef  88 , or any combination or plurality thereof simply by increasing or decreasing the volume of water contained within the bellow  20  of each of the independently controlled telescopic-module  10 . 
       FIG. 10  is a cross sectional view (taken from  FIG. 8 ) of the chamber  42  within the confines of the pool floor  124 . The chamber  42  is comprised of the chamber-wall  44  thereto communicating with the chamber-floor  46  of the chamber  42  for establishing the chamber-perimeter  86 . Furthermore, communicating with the chamber-wall  44  of the chamber  42  is a raceway  128 , thereto communicating with a water volume control station (not shown) located outside the confines of the pool  123 . The plurality of the supply-tube  36  is extended from each of the telescopic-module  10  to the water volume control station (not shown) beyond the confines of the chamber  42  through the raceway  128 . The raceway  128  also provides for chamber  42  access during construction, and maintenance of the plurality of the telescopic-module  10 . The water volume supplied or withdrawn to or from each of the telescopic-module  10  is controlled independently by means of a computerized valve system, causing the bellow  20  to extend or retract respectively, thereto causing the telescopic-module  10  to extend or retract respectively. The totality of telescopic-module  10  within the confines of the chamber  42  are programmed to either remain in part with a predetermined dormant-reef  94 , or are programmed to establish the predetermined size, and shape of a specific reef, or plurality of reefs. The basic reef configurations are shown in  FIG. 6B ,  FIG. 6C ,  FIG. 6D . The predetermined width  108  of the diagonal-right-reef  92  is shown communicating with the dormant-reef-width  109  of the dormant-reef  94 . The elevation, and horizontal plane of a static-water-line  112  is disrupted by the wave  114  kinetic-energy  54 , thereby creating a dynamic-water-line  122 . As the kinetic-energy  52  within the water approaches the toe  98  of the diagonal-right-reef, the kinetic-energy  52  becomes increasingly retarded relative to the energy at the water&#39;s surface to a specific depth (which is dependent upon several factors). This “dragging” effect increases until the kinetic-energy  52  reaches the plateau  104  and a crest  116  advances beyond the relative position of the kinetic-energy toward the depth of the water, creating a face  120  of the wave  114 . Overcome by gravity, the mass of the water above the static-water-line  122  at the crest  116  and the wave  114  begins to collapse and create the peel  118  in a direction influenced by the advancing direction of the diagonal-right-reef towards a beach (not shown). Hence, the peel  118  direction is to the right, thereto providing a “barrel” or riding surface for the surfer as the wave  114  continues to generate the peel  118  and finally decay toward the beach (not shown).
