Abstract

The present paper deals with the monthly interval variation of physico-chemical characteristics of River Betwa during October 2011 to August 2012. Five major sampling station (10 sites) were selected:  station- I Jhirri (1 to 2 sites), station- II Nayapura (3 to 4 sites), station- III Mandideep (5 to 6 sites), station- IV Bhojpur (7 to 8 sites) and station- V Vidisha (9 to 10 sites). Various physico-chemical parameters like temperature, pH, hardness, dissolved oxygen (DO), biological oxygen demand (BOD) and chemical oxygen demand (COD) and correlation co-efficient were measured, and standard methods were applied in the present work. Studies revealed high values of hardness, BOD and COD at station II Nayapura and station III Mandideep, and low values of DO and pH at the station - station I Jhirri, IV Bhojpur, and Vidisha low values of hardness, BOD and COD. High value of hardness, BOD and COD indicate the river water polluted at station II Nayapura and station III Mandideep.

Key words: Betwa River, Mandideep, Nayapura, physico-chemical parameters.
