Abstract
　Several current records on flood hazards celarly exhibit the nature of floodings and consequent damages that have been incresing in urbanized small-scale watersheds. Then the approach to the problem of urban inundation needs to introduce measures suitable for each hazardous area through analyzing the mechanism of urban system and behavior of consciousness of inhabitants.
　From these viewpoints, the structural modeling method is proposed in order to construct the consciousness structure of flood hazard problem and the living environment. Two modeling methods which are a method using the AIC and a structural method of awareness movement are proposed in this study.
　As the results, it is observed to be imperative to attach importance to the parameters of disaster and disaster prevention along with the lving environment. The residents’experiences of flood hazard are useful to enhance the consciousness of flood hazard prevention. Besides, the public information system of flood hazard have infiltrated into these areas gradually.
