Details
The study confirmed that Transfer Function models are able to provide a robust, fast and accurate approach to flood forecasting provided that models are applied within their calibration range and that users have a good understanding of the assumptions and limitations of the approach. Results can also sometimes be extended to higher flows where models incorporate some notion of catchment response (e.g. parallel pathway models, or models using an effective rainfall preprocessor) and/or use real time updating.
