Abstract:
The seasonal variation of River Kolar at Saoner was studied for a period of one year. In the present study various physico-chemical parameters were analyzed for various seasons; summer, monsoon, winter from the period of August 2012 to July 2013 in surface water of river Kolar including macroinvertebrates diversity. The present study revealed that the physico-chemical parameters showed a great seasonal variation. Seventeen genera belonging to seven orders of macroinvertebrates were found which include Ephemeroptera, Diptera, Coleoptera, Hemiptera, Plecoptera, Odonata and Trichoptera indicating good quality of water. Correlation between the hydrological attributes showed good relationship and Transparency, dissolved oxygen and pH were found to be most important variables in shaping benthic faunal assemblage.
