Understanding the relative role of hillslope processes and geomorphology in Alpine catchments

Hydrologic prediction in small Alpine catchments (up 50-200km2) plays a crucial role for water and flood man- agement in downstream areas. In this generally steep environments, understanding the relative role of hydrologic processes in the hillslopes and o ...

Effects of successive floods on bed load transport in a steep flume.

Christophe Ancey, Joris Heyman, Blaise Etienne Marceau Dhont, Pascal Venetz

Rivers in mountainous areas are subject to cyclic perturbations due for instance to summer storms or daily variations in snowmelt. Such phenomena cause successive floods occurring under very similar forcing conditions. However, as shown by several field st ...

Detection of Floods In Sar Images with Non-Linear Kernel Clustering and Topographic Prior

Jean-Philippe Thiran, Devis Tuia, Frank Grégoire Jean de Morsier, Maurice Borgeaud

After a major flood catastrophe, a precious information is the delineation of the affected areas. Remote sensing imagery, especially synthetic aperture radar, allows to obtain a global and complete view of the situation. However, the detection of the flood ...

Flood Risk Management of the Avançon river – physical model based study

Anton Schleiss, Tamara Ghilardi

The sediment transport capacity of the Avançon river through the city of Bex in Switzerland is limited. During the October 2000 flood event, water levels rose to danger limits. After the flood, the river channel was completely filled with sediments, with a ...

Flood management in a complex river basin with a real-time decision support system based on hydrological forecasts

Javier García Hernández

In alpine valleys with strong urban development, river training works for flood safety become more and more difficult to implement because of economic and environmental constraints. Thus flood management has a great importance especially in river basins eq ...

Impact of flood deposits on earthworm communities in alder forests from a subalpine floodplain (Kandersteg, Switzerland)

Claire Guenat, Géraldine Michèle Bullinger, Jean-Michel Gobat, Renée-Claire Le Bayon

In many ecosystems, bioindication is a tool to estimate biodiversity and quality of environment. In soils,invertebrates are generally suitable bioindicators, especially earthworms. In floodplains, young alluvial soils are exposed to sedimentation and erosi ...

Modelling and simulation of floods in alpine catchments equipped with complex hydropower schemes

Anton Schleiss, Martin Peter Bieri

The simulation of run-off in an alpine catchment area equipped with complex hydropower schemes is presented by the help of an especially developed tool, called Routing System, which can combine hydrological modelling and operation of hydraulic elements. In ...

Flood forecast uncertainty and alert decision. application to the alpine Rhone river catchment / Incertitude des prévisions de crue et décision d’alerte. Application au bassin du Rhône Alpin

Javier García Hernández

The main goal of the 3rd Rhône Correction project in Switzerland is to improve the flood protection in the Upper Rhone River basin. In this framework, the MINERVE project contributes to the flow control during flood events by preventive turbine and bottom ...

Saturation of curvature-induced secondary flow, energy losses, and turbulence in sharp open-channel bends: Laboratory experiments, analysis, and modeling

Koen Blanckaert

The paper investigates the influence of relative bend curvature on secondary flow, energy losses, and turbulence in sharp open-channel bends. These processes are important in natural streams with respect to sediment transport, the bathymetry and planimetry ...

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 ...
