the study on water level fluctuation in the urmia lake has become of a great importance in recent years. this is due to the importance of the position of this lake as a natural heritage at an international level. the water level decrease at the urmia lake during the recent years has made it necessary to address the matter more than before. investigation and assessment of changes in the lake is ...

[1] The Great Salt Lake is a closed basin lake in which level and volume fluctuate due to differences between inflows and outflows. The only outflow is evaporation, which depends directly on lake area and salinity, both of which depend on lake volume. The lake’s level, volume, and area adjust to balance, on average, precipitation and streamflow inflows by evaporation. In this paper, we examine ...

—The Green Lake, Wisconsin, strain of lake trout Salvelinus namaycush was discontinued as a hatchery brood stock in 1976 after Lake Michigan was stocked with the 1975 yearclass. In 1982, a decision was made to restore the Green Lake strain as a production brood stock. Five groups were produced by spawning marked fish that were survivors from the 1976 stocking of southern Lake Michigan. A sixth ...

Three-dimensional modeling of lake morphometry enables the calculation of lake volume, planar surface area, and basin surface area, which are critical components of a conceptual model of how planktic and benthic habitat areas change with changing lake level. We have applied three-dimensional modeling to Foy Lake, Montana, and compared model results of changing ratios of planktic and benthic hab...

Probabilistic Bayesian networks have been used as decision making tools mainly in medicine and economics, but recently they have also been utilized in natural resource management. In this study a Bayesian model is built as a decisionmaking tool for fisheries management in the Tonle Sap Lake in Cambodia. As the largest freshwater fishery in the world, the Tonle Sap has enormous importance to bot...

An overall and comparative ecological risk assessment of heavy metal pollution (including Cu, Zn, Pb, Cd, Hg, Cr, As, and Ni) in surface sediments was conducted for six major shallow freshwater lakes (Taihu Lake, Chaohu Lake, Nansihu Lake, Dongting Lake, Poyang Lake, and Hongze Lake) in China. A spatial database with 339 sediment samples was created through an extensive literature survey. Conse...

Present study aims to unravel the hydro geochemical interaction of sediment and water of Saheb bandh lake, West Bengal, India with an emphasis on heavy metal assessment. Lake water belongs to Ca2+–HCO3− type hydro geochemical faces and water-rock interaction primarily controls the lake water chemistry. Based on different Hydro chemical characteristics it is suggested that silicate weathering is...

This study is a contribution to the study of the spatial evolution of the properties of the municipal lake of Yaounde-Cameroon. The objective was the characterization of the physico-chemical, bacteriological and organoleptic parameters of water of this lake in order to provide the scientifically exploitable data. To understand the sources and the evolution of the pollution of this lake, we carr...
