This relation indicates that the influx parameter is mainly influenced by the local topographic and geomorphologic parameters.It is considered that the overland flow influx process on slope dominated in a watershed with a smallθ,while in a watershed with a largeθ,the channel flowinfluxprocessdominatedinstead.Traditionally,K2=0.318 and b=0.204 are the recommended values in this area(Rainstormrunoff calculation method in small watershed,1984).However,For the watersheds with high vegetation coverage or fractured rocks,which might decrease the influx efficiency strongly,m should be modified smaller by plus an coefficient C that can also obtained by table lookup as listed in Table 3.As it is very difficult to quantitatively express the geomorphologic conditions,we use Cmean to modify the parameter m in this work.
