Preparing a river treatment development plan requires reasonable and reliable design of flood outcomes.Taking the design flood calculation of Wanquan River as an example,the historical flood recurrence period was analyzed,the consistency of the flood series of the hydrological station was carried out,the correlation between peak and volume of main stream hydrological stations was established,the flood series was interpolated and extended,and the design floods of the hydrological stations were determined.According to the construction time of reservoirs with regulating and storage functions in the river basin,the interval design floods of different zones were calculated.The flood encounter situation in the river basin was analyzed.The typical annual method and the same frequency method were used to analyze the area composition of the designed flood.The measured flood process of the typical year was selected as the typical flood process by using the flood volume control in the zoning period,and the design flood process line of the flood control section was deduced.
