Abstract:
A review of flood forecasting hydrometeorological forecast technology is presented with application of watershed quantitative precipitation forecasts in flood forecasting, hydrological model, and uncertainty analysis of hydrometeorological forecasting. The results show that gridbased watershed quantitative precipitation forecasting with forecasters’ forecasts is an important means of improving the accuracy of watershed quantitative precipitation forecasting in flood forecasting operations, and regional ensemble weather prediction modeling is the main method to improve local heavy precipitation forecasting. The distributed hydrological model, based on control volume method with coupling conceptual runoff generation module and physical routing module, is the developing direction of hydrological model for flood forecasting. Hydrological ensemble prediction is the most popular methods for the uncertainty analysis of hydrometeorological forecasts and the models based on Bayesian theory are one of the most effective solutions to the forcast uncertainty.
