Abstract

The present study assesses the epilithic diatom communities in river in relation to environmental conditions. Epilithic diatoms and water samples were collected in 5 locations during summer season (May 2012). Analysed data were interpreted and the results are represented. Two statistical methods were used in this study; Canonical correspondence analysis (CCA) and Principal component analysis (PCA) were used to determine the species distribution and environmental gradients along vary with physical and chemical variables. A total of 37 diatom species distributed among 17 genera were recorded. The significance of water quality difference among the sampling sites was expressed by four strastical methods. Highly polluted water contain diatom species like Pleurosigma salinarum, Nitzschia thermalis, Gomphonema parvulum, Gomponema lanceolatum, Fragilaria intermedia in the densely populated and highly industrialized locations and slightly polluted water present the diatom species like Achnanthes minutissiuma Kutz, Cyclotella catenata and Cymbella tumida among sampling sites.
