Application of the Artificial Neural Network Method to Forecast High Sediment Percentage Flood

In the foun dation of traditional forecasting flood methods,the neural network technology is adopted to forecast flood transfer history with high sediment percentage.Using the neural network method,the intelligent models are setup,and the recognition mechanism of flood with high sediment percentage is explained.The least mean square method is adopted to train intelligent models and through the neural network thinking flood water level,the discharge and sediment percentage are forecasted.There are very important value and far-reaching significance to study the theory and technology of forecasting the flood with high sediment percentage.
