Lake Geneva boatmen used to refer to slow oscillations in lake level as "seiches". By analogy, this name has been applied to certain slow oscillations in sea level that occur in ports or bays.
Seiches are periodic oscillations, damped or sustained, in large bodies of water (roadsteads, harbor basins, canals, straits, lakes, etc.). They are gravity waves, with periods ranging from an order of magnitude minute to several hours.
