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.

Nutrient relationships in shallow water in an African Lake, Lake Naivasha
Oecologia, 1981In 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%.

TBT Causes Regime Shift in Shallow Lakes
Environmental Science & Technology, 2006Tributyltin (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, 1992The 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, 2009Different 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 ...

Nonstationary models for shallow lakes
Asymptotic Analysis, 2000In this paper we study the behaviour of solutions of Navier–Stokes equations with adherence to the bottom and traction by wind at the surface when the aspect ratio $\delta=\hbox{depth}/\hbox{lenght}$ of the domain tends to 0. Precisely, we prove that when wind is moderate, a variational solution converges to the solution of a vertical diffusion model ...

Life at the Shallow Lakes: Bioarchaeological Record of the Northern Pampean Shallow Lake Environment
Skeletal remains have provided key evidence of early human presence in the northern area of the Pampas (Argentina). This contribution reviews the mortality profile and paleopathological data from this region, focusing on the study of human remains found in the Central Pampean Dunefields (General López, Santa Fe, Argentina).Píccoli, Carolina Valeria +2 more
