Study the qualitative Canada of the Sardabrood River in Mazandaran with the use the qualitative indicator of Canada׳s water

The rivers are considered as a small part of flowing water and one of the basic sources of the world׳s irrigation, drinking water industry and other uses. The aims of this study are division of water quality in three stations (Zawat, Walt and Roodbarak) which are situated in Sardabrood river by using qualitative water index (CWQI) and the Aquachem software. For this aim to calculate the indicator, calcium, magnesium, potassium, sodium, Chloride, Sulfate, The electrical conductivity (EC) and acidity (PH) based on the results, Zawat station is in a rather good rating for potation and in an excellent rating for irrigation and Walt and Roodbarak had bad ratings. All the Roodbarak stations are in bad conditions for raising aquatic amusement and are needed to be filtered and refined. Concerning to the analysis, the best and worst qualitative water is related to the Zawat and Walt and Roodbarak stations. The type of water by the Aquachem was Bicarbonate- Sodium (NaHCO3).
