Researchers from the Polish Academy of Sciences and the Warsaw University of Life Sciences have developed a comprehensive database documenting the water levels of the Vistula River in Warsaw. The dataset includes more than 82,000 daily measurements covering a 225-year period from 1799 to 2024.

To establish this unified series, scientists standardized various historical measurement units, including Rhenish, Old Polish, New Polish, English, and Russian inches, alongside the metric system. The team also employed machine learning to fill historical data gaps by correlating Warsaw’s water levels with readings from other locations like Toruń. The study, published in ‘Earth System Science Data’, tracks the river’s hydrological changes from the end of the Little Ice Age through the current era of climate warming.
