Application of Information Diffusion Theory in Flood Risk Analysis

In this paper the risk analysis method, based on information diffusion theory, was used to advance a model for flood risk analysis. Application of the model was also illustrated taking the Jinhuajiang and Qujiang drainage basins as examples. The study indicated that the model exhibited fairly stable analytical end result, even in a small sample condition. The result also indicated that the information diffusion technology is highly capable of extracting sufficient useful information and therefore improves the system recognition accuracy. The method can be applied easily and its analytical end result is easy to understand. It may play a guiding role on disaster prevention to some extent.
