Radar-rain gauge merging and discharge data assimilation for flood forecasting in Alpine catchments

Alain Tommy Foehn

Floods are responsible for one third of the economic losses induced by natural hazards throughout the world. To better protect the population and infrastructures, flood forecasting systems make us of weather forecasts to foresee floods several days in adva ...

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 ...

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 ...

Los desafíos de la modelización hidrológica y la previsión de crecidas en tiempo real en alta montaña

Anton Schleiss, Javier García Hernández, Alain Tommy Foehn

Flood forecasting systems are today recognized as a key element in natural hazard mitigation. The objective is to exploit the available observed and forecasted meteorological information to foresee river discharges up to several days in advance, using a hy ...

El sistema operacional MINERVE para la previsión de crecidas en el Cantón de Valais, Suiza

Javier García Hernández, Alain Tommy Foehn

In recent decades, the watershed of the Rhône River, upstream of Lake Geneva in Switzerland, has suffered three major floods that have caused damages for over 500 million dollars. This led to the third correction of the Rhône River, which aims to improve f ...
