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...

In recent years due to increase of drought frequency, lakes water levels, in arid and semi-arid regions of the Iran, have dropped significantly. Therefore, in addition to ecosystem degradations, drought challenges socio-economic sectors as well. The purpose of this study was to evaluate the water level fluctuations of Parishan Lake during the wet and dry periods, and the impact of drought indic...

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...

Spatiotemporal modelling of land use/cover change (LUCC) has become increasingly important in recent years, especially for environmental change and regional planning. There have been many approaches and software packages for modelling LUCC, but developing a model for a specific region is still a difficult task, because it requires large volume of data input and elaborate model adjustment. Fuxia...

Long-term information of phytoplankton bloom is critical for assessing the processes driving blooms in lakes. A three-decade survey of the phytoplankton blooms was completed for Erhai Lake from 1987 to 2016 with Landsat imagery. A modified three-band model using Landsat broad bands is developed by comparing reflectance data from Landsat imagery to two field datasets. The model is applied to the...
