Abstract: A new method of estimating the economic loss caused by dam-break by dividing flood inundated area is proposed based on the characteristics of flood propagation and property damage. In order to determinate the property damage rate, the flood inundated area is divided into six zones breach zone, destructed zone, severely affected zone, medium disaster zone, slightly affected zone and safe zone. The criteria of zoning and the property damage rate of each zone are given. Furthermore, a method of dividing the inundated area is proposed based on matter-element model to avoid inconsistency. The estimation method saves workload, and is convenient and rapid.

Key words: dam-break, economy, property damage rate, estimation, regionalization
