A long term hydrological simulation was conducted for the Huaihe River Basin by a coupled land surface-hydrology model from the year 1951 to 2006, forced with NCEP reanalysis data and observed precipitation. Three data series, observed precipitation, simulated and observed streamflows, are used to grade extreme hydrological events for reducing uncertainties caused by errors of observation and simulation, and impacts of human activity on observed streamflow. The period, intensity, position, and variations duration of extreme hydrological events was analyzed with the Morlet wavelet transform. Results showed that extreme hydrological events occurred more frequently in the basin in last half century due to the global environmental changes. Future water resources security of the Huaihe River Basin is facing large challenges as the projection of IPCC AR4 reports.
