Flood Management in a Complex River Basin with a Real-Time Decision Support System Based on Hydrological Forecasts

During the last decades, the Upper Rhone River basin has been hit by several flood events causing significant damages in excess of 500 million Swiss Francs. From this situation, the 3rd Rhône river training project was planned in order to improve the flood ...

Decision Support System for the hydropower plants management : the MINERVE project

Anton Schleiss, Javier García Hernández

The MINERVE project was initiated for flood management in the Upper Rhone river basin. Its first goal is the prediction of floods. The second one is the optimum management of the complex system of hydropower plants located in the basin in order to diminish ...

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 ...

Influence of pumped storage operation on flow conditions near intake/outlet structures : in situ measurement using ADCP

Anton Schleiss, Giovanni De Cesare, Michael Müller

In the framework of a research project studying the influences of pumping/turbine modes on turbulence, flow fields and suspended sediments in reservoirs, prototype measurements are carried out at the Grimsel II pumped storage plant (Switzerland). In situ r ...

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 ...

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 ...

Interaction of side weir overflow with bed-load transport and bed morphology in a channel

Burkhard Rosier

Side weirs, also known as a lateral weirs, and overflow dams are free overflow regulation and diversion devices commonly encountered in hydraulic engineering. They are set into the side of a channel or river allowing to spill a part of the discharge over t ...

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 ...

Stochastic generation and disaggregation of hourly rainfall series for continuous hydrological modelling and flood control reservoir design

André Musy, Anne-Catherine Favre

In the urban environment, stormwater detention basins are a powerful means to limit the frequency of sewer system failures and consecutive urban flooding. To design such waterworks or to check their efficiency, it is possible to carry out continuous rainfa ...
