Analysis of the ecological state of the river using a synergistic information index on the example of the River Debed
Waters of the Debed River are weakly alkaline, water mineralization is averageand the oxygen regime is sufficient for normal vital functions of aquatic ecosystems. In the water of the river Debed content of suspended particles varies over a wide range. For the first time using synergistic information index (SII) water quality of the river Debed was assessed. The correlation between the SII and other indices of water quality was conducted. It was shown that SII has a linear relationship with the Canadian Water Quality Index and an inverse relationship with the index of water pollution and specific-combinatorial index of water quality. It was established that from the source to the mouth of the river there is a decrease in water quality. The cause of pollution is the high content of metals.
