Urbanization is taking place rapidly in developing countries. There are many problems of urbanization, and flood hazard is one of the serious problems. Flooding events and hydrologic process are complex in urbanized watershed. Current methods for urbanized watershed flood hazard risk assessment exist shortage. With the advance of observation technology and geographic information system technology, the multi-source spatial-temporal data have been collected increasingly. The data driven methods have provided a potential solution for the complex urbanized watershed flood hazard risk assessment. The paper has discussed the complexity of urbanized watershed flood hazard. The framework of observation based modeling of urbanized watershed flood hazard risk assessment has been given. Multi-source spatial-temporal information fusion approach for watershed flood hazard risk assessment has been discussed. A case of Hanyang urbanized watershed has been developed based on the multi-source information fusion method of local weighted linear combination.
