Field data, collected in a shallow underflow into a medium-sized reservoir, show that the dimensionless entrainment, E , is non-negligible at high Richardson numbers. For such underflow, the field data demonstrate that E is mainly dependent on t[...]

Several sets of experimental data on conveyance capacity, the division of flow between a main river channel and its floodplains, boundary shear, and sediment transport in overbank flow are presented. The strengths and weaknesses of various 1-D m[...]

This paper presents a two-dimensional model to solve the vertically averaged shallow water and sediment transport equations for short- and long-term simulations. The model implements a four-time-step explicit scheme that permits longer time step[...]

Experimental observations showed that in a compound channel, the free surface elevation transverse to the flow direction in the main channel is different to that in the floodplain in the vicinity of the end section. The non-horizontal transverse[...]

Successfully modelling flows over a spillway and on strongly vertically curved bottoms is a challenge for any depth-integrated model. This type of computation requires the use of axes properly inclined along the mean flow direction in the vertic[...]

The objectives of this contribution are to analyse and quantify the segregation process of dry granular avalanches, both parallel and perpendicular to the flow. Experiments were carried out using two dry granular mixtures, a steep chute of varia[...]
