Wave pool and wave generator for bi-directional and dynamically-shaped surfing waves

1. A wave pool having a length, the wave pool comprising:

a channel for containing water at a mean surface level, the channel having a first side and a second side, at least a portion of the channel having a cross-section, between the first side and the second side normal to the length, that comprises:

a deep region in the channel at least partially along the length of the wave pool and proximate the first side, the deep region having a mean first depth below the mean surface level of the water contained in the channel;

a reef at least partially along a length of the deep region, the reef extending upward and away from the deep region to a mean second depth that is shallower than the mean first depth of the deep region, the reef comprising at least one reef module attached to a bottom surface of the channel proximate the deep region, the at least one reef module comprising a rigid bottom surface coupled to the bottom surface of the channel, a flexible top surface, and a wave damping mechanism, the wave damping mechanism comprising a texture member attached to a top surface of the reef module; and

a beach region that slopes up away from the reef toward the second side to expose a beach above the mean surface level of the water, the beach region having a convex parabolic shape with a slope that decreases toward the second side of the channel

a track proximate the first side, the track at least partially in the water of the channel; and

at least one foil configured to traverse the channel via the track and further configured to generate a wave in the channel, the at least one foil being substantially symmetrical around a central vertical axis and configured to generate a right breaking wave and a left breaking wave in response to traversal of the at least one foil along the track, the at least one foil further configured for bi-directional movement along the track.

2. The wave pool in accordance with claim 1 , further comprising a gutter between the beach and the second side of the channel, the gutter being defined by a first side, a bottom and a second side, the first side descending from the beach to the bottom having mean fourth depth below the mean surface level of the water in the channel, the second side ascending from the bottom to a height above the mean surface level of the water.

3. The wave pool in accordance with claim 2 , further comprising one or more water return channels from the gutter through at least part of the beach region, to guide water in the gutter back toward the deep region.

4. The wave pool in accordance with claim 1 , wherein the mean second depth of the reef varies along the length of the pool in the portion of the channel.

5. The wave pool in accordance with claim 1 , further comprising a first trough adjacent the reef opposite the deep region, the first trough having a mean third depth that is deeper than the mean second depth of the reef.

6. The wave pool in accordance with claim 1 , wherein the reef includes one or more reef modules attached to a bottom surface of the channel proximate the deep region.

7. The wave pool in accordance with claim 6 , wherein at least some of the one or more reef modules include one or more wave damping mechanisms.

8. The wave pool in accordance with claim 5 , further comprising a second trough in the deep region, the second trough having a mean fifth depth that is deeper than the mean first depth.

9. The wave pool in accordance with claim 8 , wherein the mean fifth depth varies along the length of the wave pool.

10. The wave pool in accordance with claim 1 , wherein a shape of the channel is selected from the set of shapes that consist of: a linear channel, a circular channel, a curvilinear channel, an oval channel, or a U-shaped channel.
