Through the analysis of hydrological characteristics of watersheds in the upper reaches of Fenhe River
a distributed hydrological model at a catchment scale was constructed.The runoff yielding and sink flow model of SCS and the Muskingum method were firstly combined to determine discharge process in the area.Moreover
taking slope angle and slope orientation as the main indexes
a watershed was divided into sub-catchments by natural draining divide.To test accuracy of this model
the catchment of the Lanhe River in the area was chosen as a typical catchment.Results show that calculated runoff yielding and sink flow account for 70% and 80% of the observed dada
respectively
and simulated discharge process is basically coincident with observed discharge process.The model is suitable to modeling runoff yielding and sink flow in the area.
