Gravel bar inundation frequency : an indicator fort he ecological potentiel of a river

In braiding river systems, gravel bars fulfill important ecological functions. At the River Sense, one of the last unregulated rivers in Switzerland, the frequency of gravel bar inundation of a 2 km long site maintaining indicator species such as Myricaria ...

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 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 ...

Spillway discharge capacity upgrade at Gloriettes dam

Martin Peter Bieri, Matteo Paolo Elia Antonio Federspiel

In many countries dams are found to have insufficient flood discharge capacity with respect to updated design floods. Upgradig of spillway discharge capacity has therefore become a significant issue for operators of hydropower plants. The Gloriettes concre ...

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 ...

A limits of acceptability approach to model evaluation and uncertainty estimation in flood frequency estimation by continuous simulation: Skalka catchment, Czech Republic

In this study continuous simulation flood frequency predictions on the Skalka catchment in the Czech Republic (672 km 2, range of altitudes from 460 to 1041 m above sea level), are compared against summary information of rainfall characteristics, the flow ...

La prévision hydrométéorologique sur le bassin versant du Rhône en amont du Léman

Javier García Hernández, Frédéric Jordan

The main goal of the 3(rd) Rhone Correction project is to improve the flood protection in the Upper Rhone River basin. In this context, the MINERVE project aims contributing to a better flow control during flood events, taking advantage from the multireser ...

Aerated flows on stepped chutes with macro-roughness elements - Part I: Hydraulic characteristics

Anton Schleiss, Stéphanie Joëlle André

Uncontrolled overtopping during flood events can endanger embankment dams. Erosion of the downstream slope and scouring of its toe due to the high energy of the overflow can lead to breach formation and complete failure. Solution to overcome these dangerou ...

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 ...

Rehabilitation of St-Marc dam: Model studies for the spillways

Marcelo Leite Ribeiro, Sameh Ahmad Kantoush

The Saint-Marc dam, owned by EDF-France is a concrete gravity dam built between 1926 and 1930. It is located near Limoges (France) on the Taurion River and has currently two gated spillways, one 7.50 m wide on the right bank and the other with two passes o ...
