A flash flood routing model with artificial neural networks predictions was developed for stage profiles forecasting. The artificial neural networks were used to predict the 1-3 hour lead time river stages at gauge stations along a river. The preditions were taken as interior boundaries in the flash flood routing model for the forecast of longitudinal stage profiles, including un-gauged sites of a whole river. The flash flood routing model was based on the dynamic wave equations with

Five typhoon events were applied to calibrate the rainfall-stage model and other three events were simulated to verify the model's capability. The results revealed that the flash flood river routing model incorporating with artificial neural networks can provide accurate river stages for flood forecasting.
