Abstract :In the present study, diatom flora of Seydisuyu Stream Basin insert ignore into journalissuearticles values(Turkey); was investigated and the water quality of the system was evaluated in a statistical and biological view. Epipelic insert ignore into journalissuearticles values(EPP);, epilithic insert ignore into journalissuearticles values(EPL); and epifitic insert ignore into journalissuearticles values(EPF); diatoms were seasonally collected from 12 stations in 2012 along the Seydisuyu Stream Basin and some physical and chemical water quality parameters insert ignore into journalissuearticles values(temperature, salinity, TDS, pH, ORP, conductivity, nitrate, nitrite and phosphate); were measured during the field and laboratory studies. Biological Diatom Index insert ignore into journalissuearticles values(IBD); was used to assess the water quality of the basin and some mono insert ignore into journalissuearticles values(Pearson Correlation Index and Matrixplot Distribution Diagrams); and multi insert ignore into journalissuearticles values(Cluster Analysis and Factor Analysis); statistical methods were applied to detected all physical, chemical and biological data. According to data observed, Seydisuyu Stream Basin has II. – III. Class water quality in terms of investigated water quality parameters insert ignore into journalissuearticles values(Turkish Regulations); and a total of 48 diatom species were recorded for the basin by counting a total of 22.229 valves. Cymbella lanceolata, Diatoma vulgare, Fragilaria construens, Hantzschia amphioxys, Meridion circulare, Navicula cincta, Neidium iridis, Navicula venata, Pinnularia brebissonii, Synedra acus and Surirella ovata were the most dominant species in the region. According to result of IBD, the investigated region was in a mesotrophic state and has a moderate water quality. According to results of Factor Analysis, 9 factors explained 81.29% of the total variance and according to results of Cluster Analysis, stational similarity coefficients were determined as IBD Indices insert ignore into journalissuearticles values(0.98); > Environmental Parameters insert ignore into journalissuearticles values(0.85); > Diatom Flora insert ignore into journalissuearticles values(0.77); respectively.
