Risk management has reduced vulnerability to floods and droughts globally1,2, yet their impacts are still increasing3. An improved understanding of the causes changing is therefore needed, but been hampered by a lack empirical data4,5. On basis global dataset 45 pairs events that occurred within same area, we show risk generally reduces faces difficulties in reducing unprecedented magnitude not previously experienced. If second event was much more hazardous than first, its impact almost...

Abstract. As the adverse impacts of hydrological extremes increase in many regions world, a better understanding drivers changes risk and is essential for effective flood drought management climate adaptation. However, there currently lack comprehensive, empirical data about processes, interactions, feedbacks complex human–water systems leading to impacts. Here we present benchmark dataset containing socio-hydrological paired events, i.e. two floods or droughts that occurred same area. The...

Abstract. Droughts are often long-lasting phenomena, without a distinct start or end and with impacts cascading across sectors systems, creating long-term legacies. Nevertheless, our current perceptions management of droughts their event-based, which can limit the effective assessment drought risks reduction impacts. Here, we advocate for changing this perspective viewing as hydrological–ecological–social continuum. We take systems theory focus on how “memory” causes feedback interactions...

We investigate samples from two Italian regions, i.e. Lazio and Sicily, located in central south Italy, respectively, characterized by diverse climates. In engineering practice, the study of maxima daily rainfall values is commonly dealt with light-tailed probability distribution functions, such as Gumbel. The choice a rather than another may cause estimation errors associated to specific return periods. Recently, several studies demonstrate that heavy-tailed distributions are preferable for...

Floods are the natural hazards that causing most deaths worldwide. Flood early warning systems one of cost-efficient methods to reduce death rates, triggering decisions about evacuation exposed population. Although previous studies have investigated effect human behaviours on processes, analysing a combination behaviours, flood onset and timing limited. Our objective is explore how changes aforementioned factors can affect casualties. This done within modelling framework includes an...

What implications do societies' risk perceptions have for flood losses? This study uses a stylized, socio-hydrological model to simulate the mutual feedbacks between human societies and events. It integrates hydrological modelling with cultural theory proposes four ideal types of society that reflect existing dominant perception management: neglecting, monitoring, downplaying controlling societies. We explore consequent trajectories generated by interactions floods people these over time....

Raindrop-impact-induced erosion starts when detachment of soil particles from the surface results an expenditure raindrop energy. Hence, rain kinetic energy is a widely used indicator potential ability to detach soil. Although it recognized that knowledge plays fundamental role in studies, its direct evaluation not straightforward. Commonly, this issue overcome through indirect estimation using another measured hydrological variable, namely, rainfall intensity. However, has been challenging...

Abstract. Flash flood events are floods characterised by a very rapid response of basins to storms, often resulting in loss life and property damage. Due the specific space-time scale this type flood, lead time available for triggering civil protection measures is typically short. Rainfall threshold values specify amount precipitation given duration that generates critical discharge river cross section. If exceeded, it can produce situation sites exposed alluvial risk. It therefore possible...

In this paper, we investigate the performance of three-dimensional (3D) hydraulic modeling when dealing with river sinuosity and meander bends. bends, flow is dominated by a secondary current, which has key role on redistribution. The induces transverse components bed shear stress increases velocity in outward direction, thus generating local erosion riverbed modifications. When 3D processes prevail, computational fluid dynamics (CFD) model required to correctly predict structure. An...
