Colored dissolved organic matter (CDOM) is an important part of aquatic ecosystems and plays a key role in the biogeochemical cycle. In this study, CDOM absorption spectrum curves water quality parameters from 30 sampling sites wetlands Poyang Lake, Jiangxi Province, China, were collected October 2016. The optical characteristics spatial distribution CDOM, correlation between coefficient at wav...

The use of satellite remote sensing to estimate coloured dissolved organic matter (CDOM) and identify its potential sources is important for monitoring lake water quality implementing management strategies. In this study, taking Erhai Lake as an example based on MODIS/Aqua images in-situ measured data, we used empirical semi-empirical methods develop algorithms CDOM the fluorescence index (FI37...

â  lake urmia, the third hyper-saline lake in the world and because of its climatic, economic, social and ecological/environmental importance is a populated region in iran. recently, severe drought periods and low water levels are causing problems in this lake. therefore, it is urgent and desirable to evaluate urmia water level fluctuations in a scientific ways. urmia lake water level the same ...

background: urmia lake, the second largest hyper-saline lake of the world, has experienced lack of water and other environmental issues in recent years. now, there is a danger of the lake drying out, which will affect the region and its inhabitants. this study aimed to present a model which can relate the water level of the lake to effective factors. methods: parameters that influence water lev...

the zerebar lake is a shallow freshwater lake located in the northwestern iran. the lake is surrounded by three human activities: agriculture, tourism and dam. the present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the zerebar lake (2) if phytoplankton communities, as the indicator, are correlated with the human activities. water samples wer...

During a survey of Gahar Lake and Gahar River from 2008 to 2009 some specimen obtained by seasonal sampling in 6 stations, 3 stations in the lake and 3 stations in the river. Three different methods were used for sampling, gill net and hook in the lake and electrofishing in the river. Due to the results 3 species from 2 families in Gahar Lake and 12 species form 3 families in Gahar River were...
