Floods and droughts are natural hazards that can pose serious threats to human societies. In the last few decades, the catastrophic effects of these events have attracted global attention, which warranted the assessment of their magnitude and frequency, particularly in relation to their causes such as human action and climate change (e.g. IPCC, 2012; Dai, 2013; Blöschl et al., 2019). Currently, the quantification of catastrophic event recurrence probabilities is mainly based on direct measurements. Unfortunately, these are generally limited to the last decades to century, providing a limited window of observation that causes large uncertainties for current and future safety assessments.

Abstract
Floods and droughts are natural hazards that can pose serious threats to human societies. In the last few decades, the catastrophic effects of these events have attracted global attention, which warranted the assessment of their magnitude and frequency, particularly in relation to their causes such as human action and climate change (e.g. IPCC, 2012; Dai, 2013; Blöschl et al., 2019). Currently, the quantification of catastrophic event recurrence probabilities is mainly based on direct measurements. Unfortunately, these are generally limited to the last decades to century, providing a limited window of observation that causes large uncertainties for current and future safety assessments. Palaeohydrological research allows to extend the reference records to centuries and even millennia (e.g. Gregory et al., 2003; Brázdil et al., 2018; Herget and Fontana, 2019).
