HANZE database of historical flood impacts in Europe, 1870-2020
The number of floods and fatalities are taken directly from HANZE database, which is a multisource dataset of flood impacts and flood exposure. The mortaility rate was computed by dividing the flood fatalities in a given year and country by the total population in the same year and country. The population data was also taken from HANZE, but interpolated between available timesteps where necessary. The underlying impact data are described in Paprotny, D., Terefenko, P., and Śledziowski, J.: An improved database of flood impacts in Europe, 1870–2020: HANZE v2.1, Earth Syst. Sci. Data Discuss. [preprint], https://doi.org/10.5194/essd-2023-321, in review, 2023, and available on Zenodo (https://zenodo.org/records/8410025). The population data is described in Paprotny, D., Mengel, M.: Population, land use and economic exposure estimates for Europe at 100 m resolution from 1870 to 2020, Sci. Data 10, 372, https://doi.org/10.1038/s41597-023-02282-0, 2023, and available on Zenodo (https://zenodo.org/records/6783023).
