Abstract: Water quality is as important as its quantity. Water in nature often has impurities that prevent the use of this vital substance. For this reason, different indicators are presented for the detection and elimination of impurities in the water. In this paper, the chemical parameters of the Karun River (within the Ahwaz-Mollasani) have been investigated in order to determine the corrosion or sedimentation in the irrigation system under pressure. For this purpose, two Ryznar and Langelier indicators have been used and after the necessary calculations it has been determined that the river water has a negative Langelier index (LSI < 0) and a high Ryznar index (RSI > 8.5) during the specified time interval, indicating high acidity during this time period, which causes deterioration and decay in marine structures (especially low pH areas).
