(CDOM) and Chlorophyll-a loaded on the first principal component under the dimensional
reduction method were used for deriving the Eutrophication Index (EI). Fuzzy logic

(PCA) method. Eutrophication potential obtained from the rule-based fuzzy approach and
the multiple regressions derived from the first principal component were selected as the …
