Abstract
The paper provides an overview of the methods for hydrometric streamflow computation in the regime and real-time variants developed at the State Hydrological Institute and intended for inclusion in the technologies for automated processing and generalization of hydrological observations, which were included in the Roshydromet regulatory documents put into effect in 2017-2022. The results of further development of the methodological basis for water discharge calculations in the conditions of variable backwater are given on the example of the reach of the Ob River from Barnaul to Kamen-on-Ob. To control the reliability of streamflow computation at gauging sections, it is proposed to use the computation and analysis of dynamic (short-term) channel water balances as the most effective tool. The effectiveness of using the improved methods for streamflow computation and coordination is shown through examples.
