Probabilistic assessment of human instability in urban areas exposed to flood events Open
Floods in an urban environment are often associated with casualties among pedestrians who move to reach a safe area, due to body stability issues. Pedestrian instability is a random event that depends on the interaction between individual …

STEADY STREAMING GENERATED BY A MONOCHROMATIC SURFACE WAVE CLOSE TO A ROUGH BOTTOM Open
The velocity field within the bottom boundary layer generated by a propagating surface wave is quite important because it allows to determine the bottom shear stress, which is relevant from a practical point of view since, for example, it …

Lagrangian Measurements Of Surface Water Waves: Relation Between Drift Velocities And Set-Down Open
Since the work of Stokes on steady progressive surface waves (Stokes, 1847), there has been interest in fluid particle trajectories and associated mass flux. The original result obtained by Stokes was based on linear theory, and implied th…

On the onset of pipeline scouring: Reconciling waves and currents forcing Open
The combined action of waves and currents can lead to the generation of freespans that have significant influence on both pipeline on -bottom stability and structural integrity. Several studies have been carried out since the 80's to analy…

Seawater intrusion assessment along the Volturno River (Italy) via numerical modeling and spectral analysis Open
Surface and groundwater salinization are becoming a significant challenge to inland water quality, negatively affecting people and ecosystems in coastal areas. Even if rivers provide critical pathways for seawater intrusion, this salinizat…

A Semi‐Empirical Approach for Tsunami Inundation: An Application to the Coasts of South Italy Open
Tsunamis in the Mediterranean Sea have been increasingly investigated recently due to past destructive events. We present a novel operational approach for evaluating tsunami‐induced inundation, based on a generalization of Green's law and …

Wave-Forced Dynamics at Microtidal River Mouths Open
Microtidal river mouths are dynamic environments that evolve as a consequence of many forcing actions. Under the hydrodynamic viewpoint, river currents, sea waves and tides strongly interact, and their interplay determines specific sedimen…

Quantifying the Impact of Evapotranspiration at the Aquifer Scale via Groundwater Modelling and MODIS Data Open
In shallow alluvial aquifers characterized by coarse sediments, the evapotranspiration rates from groundwater are often not accounted for due to their low capillarity. Nevertheless, this assumption can lead to errors in the hydrogeological…
