Abstract：The calculation of design floods for small mountainous watersheds is a critical component in the planning and design of water conservancy projects and flood control.Based on the characteristics of floods in small mountainous watersheds in Hebei Province and commonly used methods for calculating design floods in ungauged watersheds,this study takes a typical small watershed in Shahe City,Hebei Province,as an example to analyze and calculate design floods.The results include net rainfall,peak discharge,and other design flood parameters.These findings aim to provide data references for deriving design floods in small and medium-sized watersheds in Hebei′s mountainous areas and to support the development of early warning plans for mountain flood disasters.
