The dike-break flood has the characteristics of short duration, fast speed and large flow rate, which will cause great influence on the safety of the people’s property in the protected area. Based on the theory of hydraulics, hydrology and risk analysis, this paper uses the technical methods such as numerical calculation and mathematical statistics to simulate the dike-break flood under design and over-standard flood in the Ganjiang River. InfoWorks RS is employed to simulate the protection area of Fengcheng Dikes in Jiangxi Province. The flood routing and factors, such as inundated depth and area, are analyzed under different simulation cases. The results provide the scientific basis for flood prevention and mitigation, disaster assessment, flood transfer and protection of the people’s property.
