We call it seiches (disturbance of body of water in an enclosed setting in this instance Taal Lake).
Vivant en communaute relativement dense au large de Bejaia, se nourrissant essentiellement de calmars et de seiches, les dauphins, une espece protegee, accompagnent souvent les bateaux sortant du port.
Seiches can slosh back and forth across the Great Lakes for hours, depending on the weather conditions.
Standing waves, also known as "seiches," are common in enclosed bodies of water like lakes and harbors where waves moving in opposite directions interact.
Lake Superior doesn't have tidal action, per se, but tidal-like seiches pile up water on one side of the huge lake via a combination of strong, ocean-like winds and high barometric pressure.
Among specific topics are wavemaker theories, generating and predicting seiches in Rotterdam Harbor basins, geotextile sand containers for shore protection, beach nourishment, major implications of sea level rise for coastal engineering and management, and the laboratory simulation of waves.
With a magnitude of 8.5 or so, and lasting three minutes or more, the "Big One" will cause severe ground shaking, landslides, soil liquefaction, ocean tsunamis and seiches (waves) in reservoirs.
Such movements develop as standing waves, where water oscillates such as in seiches (McLellan, 1965; Wilson, 1966; Neumann and Pierson, 1966; Korgen, 1995).
However, sloshing waves called seiches can arise within the harbor and cause water levels to vary as much as 1.8 meters in as little as 45 minutes.
