Dynamics of Water Qualities in a Eutrophic Water Body under Scarce Underwater Light Environment

Monitoring of distribution water qualities under various source water blending.

The main goal of this large-scale pilot distribution study was to systematically investigate the impacts of blending different source waters on distribution water qualities. The principal source waters investigated were conventionally treated ground water (G1), surface water processed by enhanced treatment (S1), and desalted seawater by reverse osmosis membranes (RO). Due to the nature of raw w...

Activity in Eutrophic Water

The aand l-glucosidase activity in natural samples can be readily measured during short incubation times (20 min) by using the artificial substrates 4-methylumbelliferyl-a-D-glucoside and 4-methylumbelliferyli--Dglucoside. The apparent Km of both aand ,I-glucosidase for these respective substrates is 0.01 ,uM. The homologous disaccharides maltose and cellobiose competitively inhibit aand I-gluc...

Virtual scarce water in China.

Water footprints and virtual water flows have been promoted as important indicators to characterize human-induced water consumption. However, environmental impacts associated with water consumption are largely neglected in these analyses. Incorporating water scarcity into water consumption allows better understanding of what is causing water scarcity and which regions are suffering from it. In ...

The effect of water column stability on underwater oil blowouts plume dynamics and peeling height

Considering the increase in number of offshore oil production projects and for better understanding of plume dynamics in accidental underwater oil blowouts, a series of laboratory experiments in a square cross section open top basin were carried out to investigate the effect of changes in seawater stratification and water column stability on plume dynamics and peeling height.  Accordingly the o...
