Applying AQUATOX to Simulate the Response of Eutrophic State to Nutrient Input in Yincun Port River

Abstract:

There is a growing interest in the application of ecological models to evaluate past, present, and future direct and indirect effects from various stressors including nutrients, organic wastes, flow, temperature etc. in aquatic ecosystems. For this study, AQUATOX simulation was established, calibrated and validated to model the aquatic ecosystem of Yincun Port River with field measured data and historical records between April 2013 and October2014. The results showed the AQUATOX simulation reasonably represented the real situation of Yincun Port. Moreover, sensitivity analysis revealed the value of Phytoplankton Chlorophyll was highly sensitive to nutrient input, temperature and parameters related to temperature limitations. Furthermore, this model was applied as a forecasting tool to analyze the response of Chl. a to nutrient input.
