  • Emissions of greenhouse gases such as CO2 and CH4 from artificial reservoirs, especially wide lakes in the tropics as the Son La hydropower reservoir, are leading to global warming. CO2 and CH4 gases in hydropower reservoirs are caused by the decomposition of organic matter in the lakes. In this study, regression analysis was used for estimating the relationships among water quality parameters measured at the Son La hydropower reservoir and the fluxes of greenhouse gas emissions from the reservoir. The regression analysis was also applied to develop regression equations predicting emissions of greenhouse gases from the lake. Results of study showed that the CO2 emission from the Son L...

  • One ofapproachesto assessing the water qualityof lakes is to look at lakes with respect to their primary productionor trophic state. Protecting water quality of urban lakes from eutrophication is an important task of all governments. This study presents an analysis of the trophic state in lakes of Dong Da district, Hanoi. The tropic states of the lakes were characterized using the Carlson TSI and the Chlorophyll-a concentrations with the thresholds of US. The deviations of the Secchi depth and total phosphorus indices from the Chlorophyll-aindex were usedtoidentifylimiting factors affecting to the tropic state of the lakes. It comes to a conclusion that most of the lake...
