Assimilation of snow depth data from Sentinel-1 to improve the hydrological model of the Borgne catchment (VS)

Since 2013, Crealp (Centre de Recherche sur l’Environnement Alpin) is operating a realtime flood forecasting system for the upper Rhone river basin. The scarcity of meteorological input data at high elevation leads to model uncertainties. In this project, ...

In Lake Geneva, a deep peri-Alpine lake in Switzerland, the sublacustrine Rhône River delta presents a deep canyon, the Rhône Canyon. Previous studies and recent observations show that low-velocity underflows and high-velocity turbidity currents pass frequ ...

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 ...

Sediment connectivity in the Rhône basin: From an isolated thunderstorm at Illgraben to a tubidity current in deep Lake Geneva

David Andrew Barry, Ulrich Lemmin, Koen Blanckaert, François Mettra

In the Rhône canyon of Lake Geneva (Figure 1), turbidity currents are occasionally present in summer. Based on velocity measurements in the canyon and discharge measurements at Porte du Scex in the Rhône 6 km upstream of Lake Geneva (Figure 1), Lambert and ...

Set-up and configuraion of an ensemble Kalman filter for an operational flood forecasting system

Giovanni De Cesare, Alain Tommy Foehn, Anne Schwob

To forecast riverine floods, short-range forecasts are normally provided. In such cases the initial hydrological conditions highly influence the predictability of a flood event. The study evaluates the potential of an ensemble Kalman filter (EnKF) for the ...
