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 ...

The effect of migrating dune forms on the flow field of an alluviral river

Koen Blanckaert

The bed of an alluvial river is highly susceptible to changes during the course of its existence. Besides variations of the large scale topography and plan form of the river, smaller scale dune forms can be observed. These recurring dune forms migrate on t ...

Flood retention in alpine catchments equipped with complex hydropower schemes - A case study of the upper Aare catchment in Switzerland

Anton Schleiss, Martin Peter Bieri, Frédéric Jordan, Alain Fankhauser

The simulation of run-off in alpine catchment areas is an important issue for the optimal operation of hydropower plants for normal flow conditions, but also during flood events. A semi-lumped numerical approach combines hydrological modelling and operatio ...

Influence of the widening of a tributary on confluence morphology: preliminary results

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, Simon Wampfler

The aim of this work is to obtain a better understanding of the morphological development in alpine river confluences, where special attention is given to the widening of the tributary channel and its influence on bed morphology evolution. Hydraulic tests ...

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 ...

An experimental study on main flow, secondary flow and turbulence in open-channel bends with emphasis on their interaction with the outer-bank geometry

Alexandre José Pessanha De Oliveira Caimoto Duarte

This research focus on the influence of bank inclination and roughness on the near-bank flow patterns which is relevant for bank protection, bank erosion and design of stable river configuration. Foregoing studies have been carried out mostly in rectangula ...

A neutral metapopulation model of biodiversity in river networks

Andrea Rinaldo

In this paper, we develop a stochastic, discrete, structured meta population model to explore the dynamics and patterns of biodiversity of riparian vegetation. In the model, individual plants spread along a branched network via directional dispersal and un ...

Probabilistic structure of the distance between tributaries of given size in river networks

Andrea Rinaldo, Amos Maritan

We analyze the distribution of the distances between tributaries of a given size (or of sizes larger than a given area) draining along either an open boundary or the mainstream of a river network. By proposing a description of the distance separating presc ...
