Distribution of TN and TP in Dongchang Lake from Sediment and Non-sediment Water Recharge Based on MIKE21
نویسندگان
چکیده
With the continuous increase of urban population, eutrophication lakes is becoming more and serious. It necessary to improve ecological environment by water supplement. In this study, TN (total nitrogen) TP phosphorus) Dongchang Lake before after replenishment were sampled measured, hydrodynamic, quality sediment MIKE21 models established. Finally, variation trend non-sediment simulated, following conclusions are drawn: During replenishment, concentration each point will rise, higher. After completion process, at decreases in turn. Under two modes, difference gradually become narrower, but The change similar that TP, caused supply, remains high next few days. This study provides an empirical basis for development lake improvement strategies.

Interactions between sediment resuspension and sediment quality decrease the TN : TP ratio in a shallow lake
The relative contributions of sediment resuspension and external nutrient loading to seasonal fluctuations of the total nitrogen to total phosphorus (TN : TP) ratio in the water column of the shallow Kirkkojärvi basin were studied. In May, the TN : TP mass ratio was above 30, but it decreased to below 10 in July–August. In October, the ratio increased again. Water quality was regulated by exter...

In this study, some metals (aluminium, chromium, copper, iron, manganese, lead, zinc and vanadium) and metalloid (silicon) were determined in water, sediment and some tissues of fish Cyprinus carpio from Mogan Lake. Fish samples were caught in March 2007. As a result of the examination of metals in the water aluminium has the lowest and silicon has the highest concentration. In sediment samples...
