| Abstract | ||
| The present study included some physical and chemical characters and epiphytic algae in Diwaniya river. Three stations were chosen on the river, the first one in the beginning of the river , the second in the middle and the third in the end of the river. The samples were collected from these stations for three months from November 2007 to January 2008. Two kinds of plant were chosen which available numerously on the sides of the river they are Phragmites and Typha for study epiphytic algae on it . The Results showed that water river was alkaline and have good oxygen content and very hard. Hardness increased towards South of the river and abundant in positives ions in the Diwaniya river. Identification of algae was reached to (70) taxa , the dominance for Bacillariophyceae ( Diatoms ) about ( 72% ) Followed by Chlorophyceae ( 14% ) the Cyanophyceae ( 13% ) , Euglenophyceae ( 1% ). In the present study epiphytic algae on Phragmites was higher than Typha for all study stations , the dominance for Bacillariophyceae species like, Nitzschia palea , Fragilaria virescens , F. crotonensis , Aulacosira granulata . | ||
