The PRESAGES device
Le dispositif PRESAGES (PREvision et Simulation pour l’Annonce et la Gestion des Etiages Sévères)
Résumé
This article presents a device for long- and medium-term low flow forecasting for the rivers of the
Rhine-Meuse basin. Monthly and daily conceptual models are implemented. The monthly model permits monitoring of the hydrological situation and the making of the long-term forecasts. The daily model is used only if a risk of severe low water levels is announced, and is based on the preliminary analysis of the recession periods.
