Application of the entropy index of water quality to determine changes in the water quality of surface water bodies

Abstract

Many methods of comprehensive water quality assessment are used in Ukraine and the world, the purpose of which is to simplify calculations, reducing them to a simple expression, which leads to an easier interpretation of water quality monitoring data and corresponding forecasting of changes in water quality over time. The Ukrainian Hydrometeorological Centre and the State Water Resources Agency of Ukraine give preference to the determination of water pollution indices and the pollution coefficient of natural waters. Assessments of pollution of surface water bodies provide an opportunity to get an idea of the nature and degree of contamination of water bodies by various chemical substances.
