The PREMHYCE project (Low-flow forecasting by hydrological models, comparison and evaluation)  aims at comparing and evaluating low-flow forecasting hydrological models for water resources management (from a few days to a few weeks ahead). Five hydrological models are used on a set of French catchments, considered as unimpaired (24 catchments) or influenced by human activities (11 catchments), essentially, by river withdrawals or dams.

Funding: the PREMHYCE project was launched in 2011 by OFB (French Biodiveristy Office; formerly AFB/ONEMA), French Ministry for Environment.

Coordinators: Charles Perrin & Pierre Nicolle (2011-2019); Charles Perrin & François Bourgin (since 2020) – INRAE Antony (UR HYCAR)

Partners: BRGM (French Geological Survey), EDF (French national electricity company), Météo-France, and Université de Lorraine.

Duration: Since 2011. Following the scientific work completed in 2014, the project partners decided to develop an operational tool for low-flow forecasting, designed for operational services for real-time implementation.

Graphical forecasting interface : Available on the sunshine platform.
