Historical changes in the annual number of large floods in near-natural catchments across North America and Europe, 1931-2010
Previous investigations have analyzed historical changes in low magnitude floods, such as the annual peak flow, at regional or national scales. These investigations often use catchments where streamflows have been influenced by human alterations such as reservoir regulation or urbanization. No known...

Previous investigations have analyzed historical changes in low magnitude floods, such as the annual peak flow, at regional or national scales.

No known studies have analyzed changes in large floods (greater than 25-year return period floods) at a continental scale for near-natural catchments. To fill this research gap, this study analyzed flood flows from reference hydrologic networks (RHNs) or RHN-like gauges in North America (United States and Canada) and Europe (United Kingdom, Ireland, France, Spain, Germany, Switzerland, Austria, Iceland, Norway, Denmark, Sweden, and Finland). RHNs are formally defined networks in several countries that comprise gauges with a natural or near-natural flow regime and that provide good quality data.
