Hydrology and hydrometeorology

CFAN's innovated research in hydrology and hydrometeorology links fundamental 

investigations into predictability and prediction to forecasts of streamflow, floods and droughts.


Innovations in hydrological forecasting include:


  • Ensemble approaches to forecasts of streamflow, floods and droughts

  • Extended time horizon forecasts of streamflow, floods and drought

  • Development of a new methodology for predicting streamflow in unguaged basins

  • Development of flood plain models for the determination of the duration, extent and depth of inundation
