Hydromorphological implications of local tributary widening for river rehabilitation

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, André Roy

The hydromorphological implications of the local widening of a tributary where it enters a confluence were investigated in a laboratory setting that is representative of the 20 major confluences on the channelized Upper Rhone River. Although local tributar ...

The Hydro-Morphological Index of Diversity: a planning tool for river restoration projects

Walter Gostner

Flood protection and river engineering projects nowadays have to improve also the ecological condition of the river. Very often the space is not available for a full restoration of the river morphology. Therefore the hydro-morphological heterogeneity has t ...

Influence of Tributary Widening on Confluence Morphodynamics

Marcelo Leite Ribeiro

In alpine regions of Europe, river training works were typically the reason for the transformation of wide and braided rivers into linear river systems with a lack of structural diversity, i.e. gravel banks, islands, woody debris, riffles or pools. These i ...

Analysis of the role of turbulence in curved open-channel flow at different water depths by means of experiments, LES and RANS

Koen Blanckaert

In order to unravel the main flow and secondary flow characteristics and the role of turbulence in a curved single-bend open-channel flow, large-eddy simulations (LES) and Reynolds-averaged numerical simulations (RANS) were carried out and compared with ex ...

Experimental study on a widening tributary channel and its influence on the confluence morphology

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro

This paper investigates the morphologic impacts of the widening of tributaries in confluence zones by means of systematic hydraulic tests performed in a confluent laboratory flume. The confluent channels are connected with an angle of 90° and the main chan ...

Flow and bathymetry in sharp open-channel bends: Experiments and predictions

Koen Blanckaert, Serban George Constantinescu

This paper focuses on experiments and simulations conducted in very sharp open-channel bends with flat and equilibrium bathymetry, corresponding to the initial and final phases of the erosion and deposition processes, respectively. The study of flow in cur ...

Stochastic sediment-Vegetation dynamics in an Alpine braided river

Paolo Perona, Peter Molnar

We propose a stochastic modelling framework to simulate the spatially lumped sediment and vegetation dynamics in a flood plain of a braided gravel bed river as an alternative to detailed morphodynamic modelling. The idea is that floods intermittently erode ...

Liquid–liquid two-phaseflow patterns andmasstransfer characteristics inrectangular glassmicroreactors

Albert Renken, Lioubov Kiwi, Anne-Laure Dessimoz

The flow of two immiscible fluids was investigated in rectangular glass microchannels with equivalent diameters of 269 and 400

\mu m

. Deionised water, dyed toluene and hexane were selected as probe fluids. Flow patterns were obtained for Y- and T-junction ...

Experimental study on the influence of the geometry of shallow reservoirs on flow patterns and sedimentation by suspended sediments

Sameh Ahmad Kantoush

The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...
