Correlation Between Water Quality and the Diversity Index of the Bosna River in the Zenica Region (Bosnia and Herzegovina)

Using the Shannon-Weaver index (H’), the link between the physical and chemical components of the biological component in the Bosnia River was examined. The results showed that pH and H’ had a strong link (rs = 0.59), while total nitrogen and H’ had a poor relationship (rs = 0.44), and COD-Cr had a weak relationship (rs = 0.34). KPK-Cr (I water class) had the lowest parameter concentrations, whereas electrical conductivity (IV-V water class) showed the highest. The values of the biological elements range from a poor 0.267 to a high state of 2.26.
