Abstract

The paper presents the results of developing a database of hydrological, meteorological, and physiographic characteristics for 1886 river gauges on the territory of the Russian Federation. The database was created using self-developed algorithms for spatial data processing. Average daily water discharges and levels were obtained from the Automated Information System for State Monitoring of Water Bodies. Watershed boundaries were delineated for each gauging station. Meteorological data were obtained from various gridded datasets: ERA5, ERA5-Land, GPCP, and MSWEP. Average daily precipitation, maximum and minimum temperatures were compared with data of meteorological observations from the resource of All-Russian Research Institute of Hydrometeorological Information–World Data Center. Physiographic characteristics were obtained for each catchment from the HydroATLAS database.
