THE USE OF AUTOMATED TECHNOLOGY TO CALCULATE THE RUNOFF QUALITY CHARACTERISTICS ACCORDING TO HYDROCHEMICAL AND HYDROLOGICAL OBSERVATIONS
To calculate the characteristics of river water flow quality, the FSBI "SHI" developed an automated software package that allows for joint processing of regime hydro chemical and hydrological information. The objective of this work is to present the capabilities of the program in obtaining characteristics of water flow quality using the example of the Luga River according to data from 2000 to 2017. The first characteristic of the flow quality is the proportion of volumes contaminated with single chemical components (Vpoll). With the use of an automated software package, the annual and long-term values of Vpoll of the Luga river runoff for each polluting component were calculated and their probabilistic estimates were given. It is shown that the upper limit of Vpoll% values for water saturation with O2 is below the norm, for the content of Mn2+, Cu2+, N-NO2, Fetot and COD was 100%; for the content of Pb2+ and oil products ‒
64-79%, for the content of O2 ‒ 39% and for other components did not exceed 16.5%. Trends in the change in annual values of Vpoll for all pollutants were calculated. The second characteristic of runoff quality is the proportion of its partial volumes contaminated with aggregates of chemical components, and assessed by classes and categories in accordance with RD 52.24.643-2002. The most polluted was the water runoff in 2006 and 2010. It is assigned to the 4th grade, category "a" and is characterized as dirty.
