Ecological Studies of the River Krishna near Gadwal, Telangana with Reference to Water Quality

Abstract

Ecological studies in the river Krishna have been studies for a period of two years (May 2015 to April 2017). Physico-chemical and phycological aspects have been investigated to assess the quality of water. The water was well oxygenated with an alkaline pH, organic matter, chlorides and nutrients were recorded at low concentrations. Diatoms constituted the dominant group of algae. Multiple regression analysis was employed to discover the relative importance of various physico-chemical variables on the abundance and distribution of algae. Mathematical equations were derived involving the physico-chemical variables for better prediction of algal number.
