Abstract– The quality of river body is determined by its physico-chemical parameters. The physico-chemical parameters refer as Temperature, Transparency, pH, DO, Free CO2, Total Alkalinity, Nitrate, Phosphate, BOD and COD. These parameters provide all necessary informations regarding the suitability of water for its use as well as for improving its quality. The present investigation is done to find out the impact of season on physico-chemical parameters of the water of River Karamnasa at Buxar, Bihar. For this purpose, various physico-chemical parameters were studied during the whole period of investigation from March 2019-Feburary 2020 and noticed the changes on the parameters due to season. The result of present finding showed that the physico-chemical parameters of the water of River Karamnasa Varied seasonally. Temperature and Free CO2 were maximum in summer while these were minimum in winter. pH, Transparency and total alkalinity were recorded maximum in summer while minimum in monsoon season. The DO was maximum in winter while it was minimum in monsoon. Nitrate, Phosphate, BOD and COD were found maximum in monsoon while these were minimum in winter.
