THE EUTROPHICATION PHENOMENON IN GOLEŞTI LAKE - ROMANIA
GABRIELA ELENA DUMITRAN | LIANA IOANA VUTĂ
Eutrophication on worldwide scale, as an effect of the anthropicimpact, is one of the most serious problems that affect the quality of the water.Existence of a large percentage of lakes with eutrophication problems, demands apredictive tool for the quality of these ecosystems.This study present the qualitative analysis of such an ecosystem, based on ecologicalmodelling. This paper proposes an ecological model (nutrient-phytoplankton) thatdescribes the biochemical behaviour of a eutrophic reservoir. The 1D modeldeveloped allows the estimation of nutrients concentration and algae biomass andnutrient limited evidence on algal growth rate. The model was calibrated andvalidated with data from 2008 and 2009 in Goleşti Lake. The model reproducesspatial and temporal concentration distribution of water quality constituents.
