Low-flow forecasting by hydrological models, comparison and evaluation
The initial objective of the PREMHYCE project was to compare and evaluate hydrological models for forecasting low water levels for water resource management in the near future (from a few days to a few weeks ahead). Five hydrological models are used on a set of French catchments, considered as unimpaired (24 basins) or influenced by human activities (11 basins), mainly through river withdrawals and dams. As the performances of these models appeared to be complementary, a multi-model approach was then implemented in an operational platform for forecasting low water levels. It provides flow forecasts for several hundred points in France, for periods of up to 90 days.
The PREMHYCE project was launched in 2011 by OFB (French Biodiveristy Office; formerly AFB/ONEMA), the Department of Water and Biodiversity (DEB) of the Ministry for Environment.

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.
