Estimation of 1D-confluence model parameters in right-angled discordant beds’ confluences using 3D numerical model
(CRC Press/Balkema, 2016)
Parameters of 1D confluence models are originally defined for concordant beds’ (CB’s) confluences. This paper aims at estimating these parameters for discordant beds’ confluences using numerical simulation results of 3D ...
On the combined effect of bed elevation discordances in the main-river and the tributary in 90° straight-channel confluences
(CRC Press/Balkema, 2016)
The role of the difference in bed elevations in the main-river (ΔzMR) and the tributary (ΔzT) at their entrance to a 90° straight-channel confluence is studied numerically using a 3D finite-volume model. Three characteristic ...
Hydrodynamic effects of debris blockage and scour on masonry bridges: Towards experimental modelling
(CRC Press/Balkema, 2016)
This paper describes the preliminary stage of an ongoing project investigating the hydrodynamic effects of debris blockage at masonry bridges. Debris blockage is cited as one of the primary causes of bridge failures in the ...
3D numerical simulation of cross-levee breaching process due to overtopping flow
(CRC Press/Balkema, 2016)
Dike failures due to overtopping flows cause severe damages. For risk management, it is of great importance to understand the mechanism of dike failure and predict flows and sediment transport in the breaching process ...
