Particle image velocimetry (PIV) using fluorescent tracer particles has been used to measure the velocity field of the fluid above self-formed vortex ripples in an oscillatory flow with suspended sediment. Measured velocities were used to find d[...]

Wave interactions with a fixed floating breakwater (FB) are investigated both numerically and experimentally. Laboratory experiments of large scale have been performed in the CIEM flume of the Catalonia University of Technology, Barcelona and me[...]

A closed expression for the dimensionless dispersion coefficient due to differential advection in the presence of wind is obtained, through integration of the associated velocity and concentration vertical profiles. Tsuruya's model is used for t[...]

In the paper a linear stability analysis of a one-dimensional morphodynamical model is presented. The local equilibrium assumption on the solid discharge is removed and a dynamical description of the bed-load transport is employed. Both unsteady[...]

A two-dimensional empirical eigenfunction model is proposed to analyze and predict the variations of riverbed profile. This model consists of two along and cross-river eigenfunctions and one temporal eigenfunction. These eigenfunctions can be ge[...]

An experimental study on long local scouring downstream of bed sills in a monogranular sand bed was carried out in the hydraulic laboratory flume at the Mediterranean Agronomic Institute of Bari (Italy). The main objectives of this study were to[...]

Soil erosion remains the principle cause of soil degradation worldwide, and the development and migration of headcuts in rills, crop furrows, and gullies can significantly increase soil losses on hillslopes, upland areas, and agricultural fields[...]

Experimental analysis of the impact of dry avalanches on structures and implication for debris flows
Zanuttigh, Barbara, Auteur ;
Lamberti, Alberto, Auteur
|
Objectives of this work are to experimentally analyse the dynamic impact of dry avalanches on structures and to examine the possibility of extending the results to debris flows; to identify structure efficiency in terms of extension and shape of[...]

This paper describes a calibration approach to relate outflow temperature to rate of outflow release from a large, vertically distorted hydraulic model designed to simulate selective withdrawal of colder water from a thermally stratified reservo[...]

A simple stochastic model is proposed to simulate floc formation due to simultaneous aggregation and breakage processes. The model is based on the constant-number Monte Carlo method where the number of flocs is kept constant during simulations. [...]

The Reynolds equations of mean turbulent flow in a two-dimensional open channel of arbitrary cross-section have been analyzed. An integral equation for the turbulent hydraulic jump is proposed. In the closure model adopted, the depth-averaged ef[...]
