Abstract

In order to measure physic-chemical characteristics of Gahar Roud River a total of 7 stations were selected in a 17km of river rout. 252 samples of water collected from the stations and were studied for their characteristics. This part of the experiment was carried out from January 2004 to January 2005. In this study, factors such as temperature, total hardness, calcium, magnesium, electrical conductivity, pH, phosphate, chlorine, BOD5, DO, TDS, TSS, SS, NTU and choliforms of samples were surveyed and analyzed. Due to the meaningful difference in the test results at the levels of 1 to 5, it can be concluded that ecological criteria of the river is in content change in its rout.
