Algorithm for Calculating the Mineralization of Riverine Waters and Salinity of Estuarine Waters from Conductivity Data

Resumo

The empirical relationship between the mineralization of riverine waters and specific conductivity normalized to 15°C was obtained in testing Razdolnaya River water from March 2013 to April 2014. It was shown that the obtained equation made it possible to calculate the water mineralization to a satisfactory accuracy for rivers of calcium–carbonate type using data on the specific conductivity and temperature obtained with a hydrological probe. It was found that the anthropogenic impact of \({\text{NO}}_{3}^{-}\) and \({\text{NH}}_{4}^{ + }\) ions on the composition of riverine water caused no significant error when using the empirical relationship. The data of the experiments showed that the salinity measurements in estuarine waters by conductivity using the oceanographic logarithm could have resulted in great errors depending on mineralization of the riverine water. The algorithm was proposed for including corrections to obtain reliable salinity values in estuarine waters.
