Neva flood database of the 19th century. Creation of a representative catalog of the first quarter of the century. Analysis of sources

This publication is a step in the creation of a representative catalog of historical Neva floods, which will be necessary for future flood forecasts as part of the study of the functioning of the complex dynamic system comprising the atmosphere, hydrosphere, and lithosphere of the Baltic-Ladoga region. The article describes the initial phase of the development of a 19th-century flood database, modeled on the 18th-century database created at the St. Petersburg branch of the Institute of Oceanology and now in use by researchers. The complexity of the study stems from an objective shortage of water level data relating to the first quarter of the 19th century.
