SYSTEMIC-ENTROPY APPROACH FOR ESTIMATING THE WATER QUALITY OF A RIVER

摘要

For the first time using the entropy water quality index, the degree of water pollution of the river Akhuryan and its tributaries Asotck and Karkachun was assessed. It was shown that from the source to the mouth of the river there is an increase in the value of the entropie water quality index and Armenian water quality index, which indicates the decline in the quality of water of the rivers from the 1st to the 4th class of pollution. After the cities of Amasia and Gyumri entropie water quality index and Armenian water quality index increase, indicating a decrease in water quality due to pollution of water in the river Akhuryan by domestic, wastewaters. It has been shown for river Ashotsk that from the source to the river mouth there is an increase in the cost of entropie water quality index, however, water quality remains of the first class. For the river Karkachun water quality was of the second class. It was established that the entropie water quality index has a linear relationship with the Armenian water quality index, water contamination index and specific combinatory water quality index and an inverse relationship with the Canadian water quality index.
