Abstract
The analysis of ecological state of the eastern part of the Sevastopol Bay by the eutrophication level using E-TRIX index is carried out. Annual dynamics of nutrients, included in the index formula, is calculated using one-dimensional version of the water quality model calibrated for the mentioned water area. The coefficients of E-TRIX correlation with the index parameters are obtained, the contributions of the parameters included in E-TRIX are assessed.
The comparison of E-TRIX index annual course in the eastern part of the bay, the Yuzhnaya Bay and the entire Sevastopol Bay is carried out.
