Definitions for "Seiche"
Keywords:  slosh, oscillate, bay, seismic, lake
A standing wave in a closed body of water such as a lake or bay. It can be characterized as the sloshing of water in the enclosing basin. Seiches can be produced by seismic waves from earthquakes. The permanent tilting of lake basins caused by nearby fault motions has produced very energetic seiches.
This is a natural process generated when wind blows in a constant direction and piles water up on a downwind shore. When the wind drops, the water is released and flows back to the opposite shore. For example, when a seiche moves towards the western shore of Lake Michigan or Green Bay, it acts as a dam, slowing the discharge of rivers and creeks into the lake or even forcing water to reverse course and move upstream (adopted from Manitowoc report, 1998). Seiches can be especially dramatic in funnel-shaped bays where great volumes of water are pushed into increasingly smaller areas. This phenomenon is particularly important at sites such as Green Bay, Chequamegon Bay, and in the estuaries associated with the St. Louis and Mink rivers.
A stationary vertical wave oscillation with a period varying from a few minutes to an hour or more. It is usually attributed to external forces such as strong winds or changes in atmospheric pressure disturbing the equilibrium of the water surface. Seiche is found both in enclosed bodies of water and superimposed upon the tides of the open ocean.
