The lake retention time for a body of water with the volume 2,000 m 3 (71,000 cu ft) and the exit flow of 100 m 3 /h (3,500 cu ft/h) is 20 hours.. Lake retention time (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake.
The list is divided in two: all lakes as conventionally defined down to 3,000 square kilometres (1,200 sq mi), and the largest lakes under a geological definition, where the Caspian Sea is considered a small ocean rather than a lake, and Lake Michigan–Huron (or "Huron–Michigan") is recognized as a single body of water.
This article lists lakes with a water volume of more than 100 km 3, ranked by volume. The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration. Lake volumes can also change dramatically over time and during the year, especially for salt lakes in arid climates.
An open lake is a lake where water constantly flows out under almost all climatic circumstances. Because water does not remain in an open lake for any length of time, dissolved solids do not accumulate, and such lakes are usually fresh water. Open lakes form in areas where precipitation is greater than evaporation. Because most of the world's ...
Such personalization refers to the manipulation of a lake’s residence time to combat internal loading and eutrophication by reducing the length of a stratification time period. Current models utilize the redirection of water flow into and out of monomictic lakes to assist in overturn and the physical “flushing” of phytoplankton and excess ...
The average lake on Earth has the mean depth 41.8 meters (137.14 feet) [9] The Caspian Sea ranks much further down the list on mean depth, as it has a large continental shelf (significantly larger than the oceanic basin that contains its greatest depths). Of the 127 registered lakes; 67 are known to be cryptodepressions.
The decomposition of organic materials can continue in the benthic and profundal zones if the matter falls through the water column before being completely digested by the pelagic bacteria. Bacteria are found in the greatest abundance here in sediments, where they are typically 2-1000 times more prevalent than in the water column. [11]
As no comparable water ramps existed elsewhere, skiers from all over North America trained at Nordic Valley until an updated structure was completed in Lake Placid, New York in 1987. The state of Utah, in coordination with the US Ski Team , built their water ramp in 1993, [ 1 ] in preparation for the 2002 Olympics. [ 2 ]
