“…The first aspect is that the development of multi-archive flood records is a relatively modern approach. Over the last two decades, a growing number of studies have reconstructed flood records spanning centuries and millennia from fluvial sediments, lake deposits, speleothems or tree-rings (Baker, 1987;Benito et al, 2004;Schulte et al, 2008Schulte et al, , 2009bWilhelm et al, 2012;Díez-Herrero et al, 2013;Wirth et al, 2013, Schillereff et al, 2014Ballesteros-Cánovas et al, 2014;Santisteban et al, 2017;Denniston and Lütscher, 2017).
