Deep learning-constrained projection of global fluvial floods and their socioeconomic implications under global warming
Fluvial floods characterized by either large volume or prolonged duration severely impede the sustainable development of socio-ecological systems, which may intensify with global warming. However, the co-evolution dynamics of joint fluvial flood characteristics and their socioeconomic implications under different global warming targets are poorly understood. Here, we combine a deep learning (DL)-constrained hybrid model, a statistical approach an…
Meteorological and hydrological dry-to-wet transition events are only weakly related over European catchments
Transitions from dry to wet states challenge water management and can lead to severe impacts. While meteorological transitions from dry-to-wet spells are well studied, it is yet unclear how, and if, they propagate to hydrological transitions. Here, we study where and why seasonal meteorological transitions propagate to drought-to-flood transitions in Europe using a large-sample dataset of hydro-meteorological observations. Our analysis shows that…
Snow drought propagation and its impacts on streamflow drought in the Alps
Snow droughts, that is negative anomalies in annual snow storage, challenge water resources management in snow-rich catchments and their downstream regions because they can lead to succeeding streamflow droughts in the following melt season. Under continued global warming, snow droughts are expected to become more frequent and intense, which likely increases the occurrence of succeeding streamflow droughts. However, we still know little about the…
Winter post-droughts amplify extreme nitrate concentrations in German rivers
Hydrological extremes can affect nutrient export from catchments to streams, posing a threat to aquatic ecosystems. In this study, we investigated the effects of hydrological drought on nitrate concentrations in the streamflow of 182 German catchments from 1980 to 2020. We found that across all seasons, 40% and 25% of the catchments showed significantly lower nitrate concentrations during drought and post-droughts, respectively, when compared to …
Temporal hydrological drought clustering varies with climate and land-surface processes
Recurrent hydrological droughts (streamflow deficits) are highly impactful and challenge water management. Regional studies have provided some evidence of drought-rich periods at specific time scales. However, it is yet unclear where and when droughts cluster in time. Here, we test for significant temporal hydrological drought clustering at subseasonal to multi-year time scales in different climate zones around the world using two different clust…
Snow-influenced floods are more strongly connected in space than purely rainfall-driven floods
Widespread floods that affect several catchments are associated with large damages and costs. To improve flood protection, a better understanding of the driving processes of such events is needed. Here, we assess how spatial flood connectedness varies with the flood generation process using a flood event classification scheme that distinguishes between rainfall-driven and snowmelt-influenced flood types. Our results show that the dominant flood g…
Reservoir regulation affects droughts and floods at local and regional scales
Hydrological extremes can be particularly impactful in catchments with high human presence where they are modulated by human intervention such as reservoir regulation. Still, we know little about how reservoir operation affects droughts and floods, particularly at a regional scale. Here, I present a large data set of natural and regulated catchment pairs in the United States and assess how reservoir regulation affects local and regional drought a…
