【Abstract】 The advances in the derivation of design flood hydrograph methods based on the recorded flow discharge data both in home and abroad are reviewed and compared.The shortcomings and the limitations of the’same frequency’and’same ratio’approaches that recommended by Chinese guidelines are pointed out.Based on the comparative study and assessment,the research directions of design flood hydrograph are suggested.更多还原
