Third correction of the Rhône River in Switzerland: physical and numerical modelling of the “Martigny bend” priority measure

Giovanni De Cesare, Azin Amini, Stéphanie Joëlle André, Irene Almeida Samora, Pierre Bourqui, Jean-Noël Saugy

The Rhône River, second largest in Switzerland, has already been corrected twice (1863-1893; 1930-1960) to ensure safety and economic development in the Rhône valley. However, in October 2000, the highest flood of the century occurred showing the limitatio ...

High velocity aerated flow on stepped chutes with macro-roughness elements

Stéphanie Joëlle André

Uncontrolled overtopping during flood events can endanger embankment dams. Erosion of the downstream slope and scouring of its base caused by the high velocity and energy of the overflow can indeed lead to breach formation until complete failure. In this c ...

Aerated flows on stepped chutes with macro-roughness elements, Part II : Energy dissipation

Anton Schleiss, Stéphanie Joëlle André

An experimental research of flow on different systems of stepped overlays for 18.6 degrees and 30 degrees slopes was conducted. In addition to define flow characteristics (Part I), the study highlighted the existence of an homogeneous aerated flow in which ...

Morphological processes and potential for lacustrine delta restoration

Alexandre Philippe Louis Antoine Fourrier, Giovanni De Cesare, Stéphanie Joëlle André

Most lacustrine deltas are nowadays highly anthropized systems. River training works during past centuries considered rivers mainly as vectors of water and sediments from a point source to a sink. However, numerous problems have been identified by resident ...

Case study – Delta restoration at a steep river mouth

Anton Schleiss, Giovanni De Cesare, Stéphanie Joëlle André, Stéphane Christian Olivier Terrier

The mouth of the Baye de Clarens torrent in Switzerland is currently constrained by lateral training walls, sequent sills and a bridge with a low hydraulic capacity. Due to a bed load trap upstream, few sediments reach the mouth. To improve flood protectio ...

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 ...

Physical and numerical model studies of the Martigny bend as part of 3rd correction of the Rhone River

Giovanni De Cesare, Azin Amini, Stéphanie Joëlle André, Jean-Noël Saugy

The 3rd correction of the Rhone River (R3) is the largest flood protection project in Switzerland so far. Covering a length of 162 km, it aims to protect some 100,000 people and prevent flood damages, which could raise up to 10 billion CHF for major events ...
