Simulation of Shallow Lake Eutrophication

2007
Natural 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, 1987
Lake 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.

Habitat suitability evaluation of a benthic macroinvertebrate community in a shallow lake

Ecological Indicators, 2018
The relations between benthic macroinvertebrate communities and eco-factors usually are nonlinear and highly complex, and are often difficult to evaluate.

Nutrient relationships in shallow water in an African Lake, Lake Naivasha

Oecologia, 1981
In the littoral zone of a shallow, tropical lake (Lake Naivasha, Kenya), average nutrient composition of emergent macrophytes along a permanent transect (0-2m depth) on a dry weight basis was: P 0.23%; N 0.96%; and S 0.11%. In the hydrosoil the average composition was much lower, sediments were: P 0.03%; N 0.24%; and S 0.05%.

Estimation of spatial distribution and health risk by arsenic and heavy metals in shallow groundwater around Dongting Lake plain using GIS mapping.

Chemosphere, 2020
Potable groundwater has become the primary water source for the local population because of the serious pollution of As and heavy metals in the surface water around the Dongting Lake Plain.

TBT Causes Regime Shift in Shallow Lakes

Environmental Science & Technology, 2006
Tributyltin (TBT) is an organotin compound used since the early 1960s as a biocide in boat antifouling paints. Its use has been linked to a host of negative effects in marine ecosystems including malformations and imposex in Mollusca and acute toxicity in many other aquatic animals.

Resuspension in a shallow eutrophic lake

Hydrobiologia, 1992
The frequency and the importance of wind-induced resuspension were studied in the shallow, eutrophic Lake Arreso, Denmark (41 km2, mean depth 3 m). During storm events in autumn 1988 lake water samples were collected every 2–8 hours by an automatic sampler at a mid-lake station.

Sediment resuspension in a shallow lake

Water Resources Research, 2009
Different mathematical formulations for the computation of the entrainment rate of sediment into suspension in lakes can produce widely disparate results under a given set of conditions, leading to problematic interpretation. In this paper, the results of a 4‐month field campaign on sediment resuspension in a large, shallow, hypereutrophic lake in ...

Nutrient reduction magnifies the impact of extreme weather on cyanobacterial bloom formation in large shallow Lake Taihu (China).

Water Research, 2016
Cyanobacterial bloom formation is dependent on nutrient levels and meteorological conditions. In this study, we elucidated the effects of extreme weather events (EWEs, heavy rainfall and strong winds) on the cyanobacterial blooms in Lake Taihu in recent ...

Dynamic behavior of sediment resuspension and nutrients release in the shallow and wind-exposed Meiliang Bay of Lake Taihu.

Science of the Total Environment, 2019
Wind-induced sediment resuspension frequently occurs in Lake Taihu, a typical large shallow lake in China. Internal nutrients release accompanied by sediment resuspension is supposed to sustain the eutrophic status and algal boom persistence.
