The UKCEH Hydrological Outlooks Portal provides interactive, dynamic access to many of the outputs of the UK Hydrological Outlook. These outputs provide information on the likely trajectories of river flows a season or more ahead, and their production is intended to help support water resources managers in their decision-making. Importantly, however, as with all forecasts, these outputs are based on model projections with many uncertainties, so should be used with caution. Users should be aware of the methodologies used to make the forecasts, and their attendant uncertainties as can be found described in the portal "about" section. There are three different forecasting approaches used for river flow forecasting in the Hydrological Outlook: - Persistence and hydrological analogues - River flow forecasts using historical climate — Ensemble Streamflow Prediction - River flow forecasts using rainfall forecasts — Water Balance Model
