摘要
The water quality (WQ) status of water bodies is highly uncertain and subjective in nature. The present paper addresses a "Fuzzy River Health Index" (FRHI) which is capable of dealing with subjectivities and uncertainties concerning river health at various sites of the Chambal River, India. By considering the parameters like temperature, total solids (TS), pH, dissolved oxygen (DO), biological oxygen demand (BOD), total coliform (TC), phosphate (P) and nitrate (N), the fuzzy model is established. The model uses triangular membership functions for fuzzification and centroid method for defuzzification. The proposed proficient method includes a fuzzy model which include IF-THEN ideas that help to determine River health using WQ parameters. The comparative performance models used are Carlson's trophic index (C-TSI),and Ecological health index (EHI). This study reveals that FRHI provides fairly good results; therefore, it concludes that the health of Chambal River is within excellent range (FRHI > 80). However, there is an urgent need to develop an effective and sustainable WQ monitoring for this study site, this proposed FRHI provides the flexibility for decision making in an integrated WQ management policies.
