The paper is aimed at the description and validation of a novel two-dimensional depth-
averaged simulation tool for highly unsteady discontinuous flows over complex time …

Mathematical modelling of river processes is, nowadays, a key element in river engineering
and planning. River modelling tools should rest on conceptual models drawn from …

Increased sediment production resulting from the erosion of unprotected soil in a catchment
may result in severe changes in the morphodynamics and hydrodynamics of mountain …

The paper tackles some important issues regarding the dynamics of mixtures of grains and
water, on the basis of a series of experiments on uniform channel flows of non-cohesive …

Abstract Laser Doppler Anemometry (LDA) and Particle Image Velocimetry (PIV) are indirect
techniques to measure flow velocities. Both require small particles in the moving fluid, both …

This text addresses the particular case of motion and causes of motion of granular material
as bedload in the fluvial domain. The aim is to perform and overview of key concepts, main …

The flow after the rupture of a dam on an inclined plane of arbitrary slope, and the induced
transport of non-cohesive sediment, is analysed using the shallow-water approximation. An …

We review different aspects of the electron-phonon interaction in bulk and structured
semiconductors. The irreversible, pseudo-polaron and true polaron regimes are illustrated in …

A cylindrical obstacle intercepting the full depth of an open-channel flow changes the
pressure field in its vincinity. In the upstream side of the cilinder, the adverse pressure …

The present work is aimed at the study of near-bed organised turbulence over mobile and
immobile, porous, hydraulically rough boundaries. The bed was permeable and composed …
