Alternative equilibria in shallow lakes
Trends in Ecology & Evolution, 1993The turbidity of lakes is generally considered to be a smooth function of their nutrient status. However, recent results suggest that over a range of nutrient concentrations, shallow lakes can have two alternative equilibria: a clear state dominated by aquatic vegetation, and a turbid state characterized by high algal biomass.

The trophic state of shallow lakes in The Netherlands
Netherlands Journal of Aquatic Ecology, 1996A study has been carried out on the development of an ecological assessment method for shallow lakes in The Netherlands. Analyses of eutrophication characteristics of 93 lakes with, in total, 127 sampling localities gave insight into some of the steering variables, such as total-P, total-N, chlorophyll-a and transparency.

EXCHANGE FLOW IN A SHALLOW LAKE EMBAYMENT
Ecological Applications, 2008Convectively driven currents can arise in the littoral zones of lakes, as a result of either differential heating or differential cooling of the shallow water. The result of these flows is to produce a surface flow away from shore with a bottom return flow or a bottom flow away from shore with a surface return flow.

Arsenic Remobilization in a Shallow Lake
Journal of Environmental Quality, 2002ABSTRACTOxic resuspension occurs regularly in shallow lakes, yet its role as a mechanism for contaminant remobilization remains ill defined. This study investigated contaminant remobilization during sediment resuspension and determined whether changes in contaminant sediment partitioning reflected the mechanisms controlling remobilization.

2007
The air smells of rain and autumn decay and sends cold, sharp fingers poking through our clothes as the Lonesome Boatman steers our little craft along the shore of the Holy Nose. Beyond the gunwales of the boat, spears of orange and emerald march up the steep hillside—the ubiquitous larch and birch, cedar and fir, muted under the thick sky.

Shallow urban lakes: a challenge for lake management
Hydrobiologia, 1999Urban lakes are very different from other lakes: they are shallow, highly artificial and often hypertrophic yet more people come into contact with them than rural, natural lakes. Our knowledge of their ecology and management is poor. This paper describes a project under the EU Life programme to understand and ecologically manage the most important ...

Simulation of Shallow Lake Eutrophication
2007Natural and man induced water pollution affects the functioning of freshwater ecosystems, restricts various water uses and risks human health. Especially, internal pollution by nutrient remobilization from sediment plays an important role in shallow water bodies.

Lake Tai: The limnology of a shallow lake in China
GeoJournal, 1987Lake Tai (Tai Hu) is located in the S part of the Yangtze River delta, has a surface area of 2,425 km2, a mean depth of 2.12 m, and a volume of 5.15 km3. The climate of the region is characterised by an average annual air temperature of 15.7°C, precipitation of 1,178 mm and evaporation from the water surface of about 1,024 mm.
