Alaknanda River originated from Satopanth and Bhagirathi kharak glacier at an elevation of 3880 m in Garhwal region of Uttarakhand. The seasonal variation of physico-chemical characteristics and phytoplankton diversity of Alaknanda River were studied for a period of one year. In the present study, various physico-chemical parameters i.e. water temperature, velocity, pH, EC, total alkalinity, calcium, magnesium, phosphate, sulfate and nitrate were analyzed during Summer, Monsoon and Winter season on selected four zones from the period of Sep. 2016-Aug. 2017. The present study revealed that the physico-chemical parameters of River water showed a great seasonal variation as DO increases in winter season. pH, EC and total alkalinity were observed highest in rainy season on every zone, which had a strong impact on other physico-chemical characteristics of River. 31 genera of phytoplankton were recorded under family as Bacillariophyceae, Chlorophyceae, Myxophyceae, Euglenophyceae and Xanthophyceae. However, the overall phytoplankton diversity was found maximum in winter and pre-summer season. The present study revealed that the existing water quality and rich phytoplankton diversity of Alaknanda River would be contributed significantly to enhance the ecosystem productivity.Pages: 353-357 | 650 Views 19 DownloadsDownload Full Article:
