Numerical Monte Carlo simulation is considered to be one of the main tools used in groundwater hydrology (1) quantify uncertainty flow predictions due imperfect knowledge aquifer architecture, hydraulic parameters, and forcing terms or (2) assess reliability approximated moment‐based equations for and/or transport. While framework conceptually straightforward very flexible, it recognized as lacking well‐established convergence criteria. Here we propose a methodology analysis simulations...
Abstract. Effective flood risk management requires a realistic estimation of losses. However, available damage estimates are still characterized by significant levels uncertainty, questioning the capacity models to depict real damages. With joint effort eight international research groups, objective this study was compare, in blind-validation test, performances different for assessment direct residential sector at building level (i.e. microscale). The test consisted common case high...
Abstract. In recent years, awareness of a need for more effective disaster data collection, storage, and sharing analyses has developed in many parts the world. line with this advance, Italian local authorities have expressed enhanced methods procedures post-event damage assessment order to obtain that can serve numerous purposes: create reliable consistent database on basis which models be defined or validated; supply comprehensive scenario flooding impacts according priorities identified...
Ecologically-appropriate management of natural and constructed surface water bodies has become increasingly important given the growing anthropogenic pressures, statutory regulations, climate-change impacts on environmental quality. The development strategies requires that a number knowledge gaps be addressed through interdisciplinary research efforts particularly focusing water-biota water-sediment interfaces where most critical biophysical processes occur. This paper discusses current...
Evaluating potential consequences of floods on cultural heritage is one the objectives 60/2007/EC Floods Directive. Nevertheless, peculiarities in terms data availability, exposure values and vulnerability, make flood damage risk analyses rarely applied. This work aims at developing a GIS-based Flood Damage Index for Cultural Heritage (FDICH) that (i) weights based level listing, (ii) vulnerability ad-hoc taxonomy, (iii) provides density per unit surface instead than point classification....
The erosion process at a bridge abutment may be affected by the flow constriction when occupies significant part of flume width. We devised specific experimental campaign to investigate effect obstruction ratio (i.e., between length and channel width) on depth: we performed homogeneous series clear-water scour experiments in each which was only parameter that varied. results are presented light dimensionless framework. It found time development local depth not large; nevertheless, can...
This paper reports the double-averaged (in space and in time) hydrodynamic equations for mobile-boundary conditions that are derived based on refined double-averaging theorems, modified Reynolds decomposition, improved definitions of spatial time bed porosities. The obtained conservation provide a mathematical framework studying flows such as gravel rivers during flood events or over vegetated beds. These will help designing measurement campaigns obtaining mobile data their interpretation...
Abstract In degraded landscapes, recolonization by pioneer vegetation is often halted the presence of persistent environmental stress. When natural expansion does occur, it commonly due to momentary alleviation a key variable previously limiting new growth. Thus, studying circumstances in which occurs can inspire restoration techniques, wherein establishment provoked emulating events through artificial means. Using salt‐marsh zone on tidal flats as biogeomorphic model system, we explore how...

The time-averaged kinematical and dynamical characteristics of the junction vortex system in front a symmetrical obstacle are systematically analyzed for both laminar turbulent flows. A wide set experimental numerical results from literature is coordinated nondimensional form together with some new computational data. In flows dimensions symmetry plane depend only on geometry; systems they also correlated Reynolds number thickness incoming boundary layer. horseshoe vortices induce shear...
A study of weak bed load over a plane is presented with particular focus on the motion and diffusion individual particles that were tracked along their movements. Grain position, velocity acceleration measured particle-scale resolution; ensemble statistics significant sample particle trajectories then computed, enabling unsteady phases (corresponding to entrainment disentrainment) be identified. Based experimental findings, physically-based conceptual model for kinematics consisting an...
Abstract Sediment particles transported as bed load undergo alternating periods of motion and rest, particularly at weak flow intensity. Bed transport can be investigated by either following the individual (Lagrangian approach) or observing phenomenon prescribed locations (Eulerian approach). In this paper, Lagrangian Eulerian descriptions are merged into a unifying framework that includes definitions for quantities used to describe kinematics particle motion, well relationships among these...
AbstractThe purpose of the present note is to contribute analysis bed-load transport processes within a Lagrangian framework. Experiments were performed tracking individual particles under different bed conditions (mobile and fixed beds) at transitional hydrodynamic regimes. A new image processing procedure was designed obtain coordinates each moving sediment intermediate range scales (corresponding particle trajectory between rests periods). Thorough attention has been paid provide...
Various forms of mass balance equations are commonly used in sediment transport studies and applications. However, the quantities involved such not always clearly defined, with flux (or solid discharge) as a typical example. Starting fundamental definitions, this paper provides general consistent framework for integral (Eulerian) balances gives scale-consistent definitions instantaneous time-averaged variables. In particular, alternative expressions averaged discharge proposed compared...
