Complementary models on the Danube River state parameters measured in the Galati area

This paper presents a research of temporal variability for water parameters on the most important river system from Romania and Europe - the Danube River. This water quality study was conducted near Galati, on the left bank of the Danube River during nine years. Using different statistical methods was made a statistical analysis in order to highlight the correlation and relationships between the water parameters. In the last section is studied a dynamical system modeling in order to recover the previous analysis´ results. The future research will be conducted for a deeper analysis of aquatic systems of this type.
