Abstract: Along with the global warming, flood disasters occur more frequently. Monitoring, early warning and assessment for disaster risk are an important way to reduce disaster losses. So it is one of the core issues in the current disaster research. On the basis of the analysis of the disaster risk, this paper described the concept, the content of warning and assessment, and ways of assessment and methods of flood disaster warning in China. This paper argued that in order to reduce flood hazard and the uncertainty of vulnerability analysis, we should explore the mechanism of flood disaster. In addition, monitoring technology was so important for risk assessment that we should improve sensor performance to increase accuracy; integrate multi-source remote sensing data; develop the "3S" integrated technology.

Key words: assessment, flood disaster, monitoring and warning, risk
