In order to accurately reflect the current runoff and flood situation in the basins, Ministry of Water Resources organizedand completed the hydrological design revision work of the seven major river basins. This paper introduced the general situation ofthe hydrological design revised achievements, and summarized the key problems such as the consistency processing of the runoffand flood series, the calculation method of the hydrological design achievements, the rationality analysis of the results, and theapplication of the revised results. This paper focused on the reduction calculation of the flood and runoff series, and theconsistency processing by considering the change of the basin underlying surface. The application of the revised hydrological designachievements and the future research emphasis was proposed.
