In the flood peak stage prediction, good results were obtained from sigmoid and linear function.

The paper analyses the variability of flood elements and the complexity of flood, puts forward three classification methods of flood grade: standardization value of flood-peak stage exceeding normal stage and probable maximum flood stage exceeding normal stage.

Application of the software of flood forecasting model to flood dispatch;

Anti-error researching of flood forecasting project of double mutual inflow reservoir;

River system flood forecasting based on artificial neural network of radial basis function;

Main framework of digital Yangtze River basin flood forecast system;

Analysis of uncertainty in flood forecast;

A rain-on-snow mixed flood forecast model and its application;

Automatic system of hydrological data acquisition and transmission and flood prediction during construction of Dalong Reservoir;

With three flood prediction schemes including rainfall-runoff prediction,upstream peak discharge synthesis method and instantaneous unit hydrograph,example prediction analysis of typical flood was conducted based on the data from Changle hydrological station on Nanliujiang river.

The new way is seeked under the condition lacking of data when compiling the plan of flood prediction.
