What are oscillatory waves in inland bodies of water referred to as?

The term used to describe oscillatory waves in inland bodies of water is "seiches." Seiches are standing waves that occur in enclosed or semi-enclosed water bodies, such as lakes or harbors, and are typically triggered by changes in atmospheric pressure, wind, or seismic activity. These waves can lead to a noticeable increase and decrease in water levels over a period of time, often exhibiting a distinct oscillatory pattern as the water sloshes back and forth.

Seiches are particularly interesting because they can create large oscillations ranging from a few minutes to several hours between the high and low water levels. This phenomenon can have significant effects on the local ecosystem and can also impact human activities around the affected bodies of water.

The other terms listed relate to different types of wave phenomena. For example, sloshes may refer to waves created by the movement of water in a container but do not specifically denote a scientific term. Tsunamis are large, powerful ocean waves generated by underwater disturbances, such as earthquakes or volcanic eruptions, and are typically not associated with inland water bodies. Sinusoidal waves refer to waves that have a smooth, periodic oscillation pattern, but this term does not specifically describe the oscillatory nature of water in a confined space
