Reconstruction of erosivity density in northwest Italy since 1701

Societies can be better prepared to face hydrological extremes (e.g. flash floods) by understanding the trends and variability of rainfall aggressiveness its derivative, erosivity density (ED). Estimating extended time series ED is, however, scientifically challenging because paucity long-term high-resolution pluviometric observations. This research presents longest reconstruction (1701–2019) in northwest Italy (Piedmont region) date, which is analysed identify damaging periods. With this aim, we developed a model consistent with sample (1981–2015) detailed novel Revised Universal Soil Loss Erosion-based data documentary extreme records. The modelled show noticeable rising trend from 1897 onwards, together an increase values for return periods 10 50 years, Clausius‐Clapeyron scaling rainfall. We also suggest North Atlantic Oscillation Multidecadal may associated Piedmont.
