Abstract
An overview of the operation and performance analysis of automated hydrological complexes (AHC) of different models and manufacturers installed on the territory of the Russian Federation for the period 2022–2024 is provided. In total, 1,100 AHCs of various types were installed on the state hydrological network as part of two waves of its modernization over the period from 2002 to 2020. The correctness of water level measurement by automated complexes and the completeness of the information received from them are assessed. A separate performance analysis is given for hydrostatic, float, bubbler and radar water level sensors. The study uses the % of data transmitting to the server on time and relative discrepancies with standard observation (stake measurements) data as numerical indicators of the AHC performance. It was revealed that the level of automation of the network of hydrological observations of Roshydromet in 2024 is 37%, and the intensity of the decline in AHC performance is estimated at 2.7% per year. The reasons for the decrease in the operability of the complexes and the future prospects for automation of the hydrological network are considered.
