Quality evaluation of river in terms of corrosion in the range of Dez – Bamdezh

Water corrosion and deposition is one of the factors to present the problem on quality management of water resources specially rivers. To control these problems, there is a need to have a regulated and exact planning. In this essay, Langelier and Ryznar s indexes were used during 2002 – 2012 to study the measurement of corrosion and deposition of Karoon River in range of Dez – Bamdezh. The results show the amount of Langelier indexes in different stations are almost 0110 – 1113. The Ryznar s indexes in Dez station is about 616 – 7.4 that is almost corrosive and a little sedimentary and it is about 510 – 611 for Bamdezh station which shows that Karoon river water in this range is sedimentary and a little corrosive.
