STATISTICAL ANALYSIS OF HYDRO-PHYSICOCHEMICAL PARAMETERS OF RIVER RUPNARAYAN, INDIA

The study deals with the physicochemical properties of river Rupnarayan. Some limno-chemical parameters like PH, DO, BOD, COD, Total Alkalinity, Total Hardness, Temperature, TDS, Phosphate, Ammonia were assessed monthly during 2019-2020 of river Rupnarayan. Principal component analysis, Cluster dendrogram, Pearson Correlation was exerted to know the similarities as well as relations between the parameters. Highest mean Total Hardness was recorded in Kolaghat (115.705 mg/l).Highest mean BOD was observed in Chitnan (2.108mg/l). Principal component analysis showed two factors were eigenvalue greater than 1. The study suggests that PH, BOD, Ammonia are positively correlated with Temperature.
