“…Many long-term reconstructions using documentary data date back to 1500 (Brázdil et al, 1999;Wanner et al, 2004;Mudelsee et al, 2006;Glaser, 2008;Stucki, 2010), some to the 15th century (e.g. Brázdil et al, 2006b;Cyberski et al, 2006;Llasat et al, 2005;de Kraker, 2006;Rohr, 2006;Glaser et al, 2010;Schmocker-Fackel & Naef, 2010), or even prior to 1400 (Barriendos & Rodrigo, 2006;Böhm & Wetzel, 2006;Benito et al, 2003;Meurs, 2007;Glaser & Stangl, 2003). Herget & Meurs (2010) demonstrated for Cologne that the two floods of the River Rhine in 1993 and 1995 were the largest documented for the period of streamflow measurements (1782-2009), but were exceeded at least four times in the pre-instrumental period.…”
