Abstract:

In duration time Karoon and Deze rivers were polluted by varios polluters ; such as : industrial ,urban and agricultural waste waters and flood-waters ; and its quality will be changed by effect of these polluters . Therefore this study were done for evaluation & classification of Karoon & Deze river's water quality were studied with consider of bioenvironmental parameters from July 2005 to June 2006. For water quality data's analysis in various station , index of water quality were used . Therefore Dissolved Oxygen , Fecal Coliform , PH , BOD5 , Nitrate , Phosphate , Temprature , Turbidity and Totalsolids parameters were determind. Then criterions quantity extracted of standard curved for each parameters.Classification of water quality of rivers were done on based of yearly WQI. The resultes has shown that in very rainy mounths in some of stations increased microbial pollutions. For example : Total Coliforms index increased up to 110000 Num/ml . E.Coli, Klebsiela, Proteus and so on separated of this study.
