RBF Model Applied to Forecast the Water and Sediment Fluxes in Lijin Section

The structure of the RBF neural network is introduced. Then the RBF model is build up to forecast the runoff and the sediment transport volume of Lijin section during the flood period and the non-flood period in 11th year according to the former 10 years' field data. Compared the RBF emulating results with the field data, the forecasting error is analyzed and the methods to improve the forecast precision are put forward.
