The concept of hydrology admits that the river flow in the mountainous basin is contributed to from two major runoff components, that is the runoff components with shorter period and it with longer period. But the river flow in a mixture of mountainous and urban areas is different because the input to the hydrologic systemis different.
In this paper, we investigate the response characteristics of the YAMATO river basin to be mixed of mountainous and urban areas by filter separation AR method. Like this, it is useful to grasp the runoff structure from the upstream region in the river to lower current area in the basin management.
