        | In fluid dynamics, a breaking wave is a wave whose amplitude reaches a critical level at which causes large amounts of wave energy to be transformed into turbulent kinetic energy |  |

        | The time interval between successive wave crests passing a fixed point |  |

        | Term 
 | Definition 
 
        | Waves refracted or reflected can interact with other waves. This action may increase or decrease wave height, often resulting in unnaturally high waves. |  |

        | Swells are waves that have moved out of the area in which they were created. |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | Local waves generated from the action of the wind on the water’s surface |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | A group of waves that seem to travel together, at the same speed |  |

        | Term 
 | Definition 
 
        | The area near shore in which breaking occurs continuously in various intensities |  |

        | Term 
 | Definition 
 
        | The distance from one wave crest to the next in the same wave group or series |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | The height from the bottom of a wave’s trough to the top of its crest; measured in the vertical, not diagonal. |  |

        | Term 
 | Definition 
 
        | Refraction means bending. Wave refraction occurs when the wave moves into shoaling water, interacts with the bottom and slows |  |
