What type of wave is a seiche?

A seiche is characterized as an oscillating wave in a body of water. This phenomenon occurs when a body of water, such as a lake, bay, or harbor, is influenced by repeated disturbance, often from wind or changes in atmospheric pressure. The oscillation results in a noticeable rise and fall of the water surface as it moves back and forth, typically influenced by the shape and dimensions of the body of water itself.

Seiches can be relatively slow, with periods that can last from minutes to several hours, leading to a distinct pattern of water movement that can be observed. Understanding this aspect of seiches is crucial, particularly in predicting their behavior and effects in various settings, such as during storms or after significant weather conditions. This knowledge is integral for those involved in environmental science, water management, and pollution response, as it helps in mitigating potential impacts on ecosystems and human activities.
