3. Surfing installation according to claim 2 , characterized in that the wave pool ( 30 ) is surrounded by a main pool ( 20 ) or by a standing or flowing body of water.

4. Surfing installation according to claim 2 , characterized in that the wave pool ( 30 ) is formed in the shape of a rectangle or in the shape of a circular sector having an inscribed angle of from 10° to 360°.

5. Surfing installation according to claim 4 , characterized in that the water inlet ( 46 ) is arranged in the region of the center ( 48 ) of the circular sector.

6. Surfing installation according to claim 1 , characterized in that the walls ( 506 , 508 ) defining the flow channel ( 504 ) are connected to the at least one drive ( 5046 ) by a link ( 5042 ), or are guided in parallel, by a plurality of synchronously actuatable drives ( 5046 ) that are each assigned to one wall ( 506 , 508 ), respectively, during a pivoting movement and/or displacement movement of the flow channel ( 504 ).

7. Surfing installation according to claim 6 , characterized in that the movement of the walls ( 506 , 508 ) defining the flow channel ( 504 ) is performed as an alternating back and forth pivoting movement or as a displacement movement, or as a rotational movement in one direction.

8. Surfing installation according to claim 2 , characterized in that the pumping system ( 40 ) for metering the discharge of the water in the water inlet ( 46 ) comprises a plurality of pumping units ( 41 ), a delivery rate of said pumping units being adjustable individually or in groups.

9. Surfing installation according to claim 1 , characterized in that the walls ( 506 , 508 ) defining a flow channel ( 504 ) are mounted such that they are vertically adjustable in order to change the width of the flow channel ( 504 ).

10. Surfing installation according to claim 1 , characterized in that at least one guide device ( 54 , 55 , 56 ; 70 , 71 ) is arranged in the wave pool ( 30 ) so as to be at a spacing from a lower end ( 52 ) of the ramp ( 50 ).

11. Surfing installation according to claim 10 , characterized in that the guide device ( 54 , 55 , 56 ; 70 , 71 ) is designed as a fixed assembly, or as an assembly that is adjustable with respect to the position and orientation thereof, or as an assembly that is completely sunk in the base ( 31 ) of the wave pool ( 30 ), said component being formed on a pedestal ( 541 ) that is raised from the base ( 31 ) of the wave pool ( 30 ).
