Application of an Ensemble Kalman filter to a semi-distributed hydrological flood forecasting system in alpine catchments

Giovanni De Cesare, Javier García Hernández, Alain Tommy Foehn, Anne Schwob

One of the key success factor for hydrological forecasts is the establishment of initial conditions that represent well the conditions of the simulated basin at the beginning of the forecast. Real-time Data Assimilation (DA) has been shown to allow improvi ...

Hydropeaking mitigation measures in the Swiss Upper-Rhône basin

Pedro Filipe De Almeida Manso, Sabine Chamoun, Mathieu Pierre Guy Barnoud, Steve Crettenand

Hydropower operations can cause hydropeaking particularly in the case of pumped storage systems located in mountainous regions. Due to the rapidly varying discharge conditions, hydropeaking leads to several problems such as stranding of fishes and inverteb ...

Improving hydropower flexibility by synergizing independently managed utilities

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun, Vincent Gaertner, Steve Crettenand

Increasing the flexibility of hydropower allows operators to produce at optimal time ranges, not only dependent on the demand flow but also on the price trends. However, the possibility to improve hydropower flexibility can be hindered when assets are mana ...

Integrated flood forecasting and management system in a complex catchment area in the Alps—implementation of the MINERVE project in the Canton of Valais

Javier García Hernández, Bastien Roquier

A complex hydrologic-hydraulic model has been developed for the Upper Rhone River basin in Switzerland. It is currently operational in the Canton of Valais for real-time flood forecasting and management, providing automatic warnings to the crisis cell of t ...

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 ...

A combined downscaling-disaggregation weather generator for stochastic generation of multisite hourly weather variables over complex terrain: Development and multi-scale validation for the Upper Rhone River basin

Abdelkader Mezghani

This paper presents a combined downscaling and disaggregation weather generator developed for multisite generation of hourly precipitation and temperature time series over complex terrain. Daily regional weather variables are first generated from Generaliz ...

Génération multi-sites de variables météorologiques horaires en zone alpine : application à la simulation de scénarios de crues du Rhône supérieur suisse

Abdelkader Mezghani

Water resources management and hydrological risks are based, to a large extent, on our competence to generate relevant hydrological scenarios under present and future climatic situations. In alpine areas, characterized by highly complex topography, the ava ...

Modèle de prévision et de gestion des crues : optimisation des opérations des aménagements hydroélectriques à accumulation pour la réduction des débits de crue

Frédéric Jordan

Floods are not only due to fatality. It is the responsibility of the human being to protect himself from heavy damages due to natural elements, and he sometimes has the chance to profit from a given situation to influence events. One of these possibilities ...
