A river confluence has the complicated characteristics of flow because of various geographical features. Therefore disaster occurrence possibility in the confluence of two rivers is relatively high compared to the general zone of river channel. In the this study, 3,836 rivers(62 national rivers and 3,774 local rivers) are investigated by using the cad-data(river survey maps), satellite and/or topographic maps to develop disaster risk assessment method for river confluence in macro view. The disaster vulnerable factors(sand bar, drop structure, bridge peer, road on channel and etc.) and the channel characteristics(confluence angle, channel bend, channel linear and etc.) which dominate river confluence are deduced with investigation results. Also, the disaster risk assessment method is developed by using AHP(Analytic Hierarch Process). Based on this method, 73 high risky river confluences are proposed and prioritized.
