Abstract
In the process of calculating water quality indices, the weight of each parameter is usually either not taken into account, and the parameters are considered equivalent, or it is given by experts according to their practical experience, which is subjective and a lot of useful and valuable information about water quality can be lost. These drawbacks can be overcome by using information entropy to assign weights to water quality parameters. As a result of the application of the entropy-weighted water quality assessment index for the section of the Dnipro River, located within the Dnipropetrovsk region, it was established that the quality of the index differs significantly in the warm and cold periods of the year. It should also be noted that one of the key factors in the formation of the entropy index of water quality is the choice of a normative value, therefore, it is promising to justify the choice of the normative value for each specific condition, which can be considered as a separate task.
