Study of some physical & chemical properties of water of Khersan River & analysis the statistical relations thereof

This article with the purpose of investigation on some physicochemical properties of Khersan River has been accomplished. These parameters are including: Temperature, Dissolved Oxygen, Dissolved Solids, Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Phosphorus, Total Nitrogen, Electrical Conductivity, Chlorophyll a, Turbidity and finally analysis of statistical relations between this parameters were developed.
To perform the tests and determine the parameters we had 12 months sampling at 6 stations.
Sampling methods and performing of examinations was in accordance with Standards method. Qualitative & quantitative variations were studied during a year and finally, data analysis through SPSS software and Pearson correlation coefficient test were performed.
Findings: The highest temperature was in station No. 1 in July 32.5 º C and the lowest was in station No. 4 in February 9.2 º C, the most electrical conductivity is related to station No. 2 in August 672 µ mhos cm-1 and the lowest was in station No. 1 in March 262 µ mhos cm-1.
Discussion and According to Iranian DOE quality standard chart of state river's water, the range of changes in dissolved solids and dissolved oxygen in water is in optimum extent. But, Biochemical Oxygen Demand of water is in maximum permitted amount. There are meaningful relations in confidence extent of P
