| Abstract: | An evaluation method of loss caused by dam breach was proposed in this paper.The calculation models estimating life and economic losses caused by dam breach were established based on GIS spatial information grid.Combining with database technology,dam breach hydraulics and computer's graphics the GIS-supported rapid estimating system of dam breach was developed.The design principle and system structure were discussed.Main performances and characteristics of the system were interpreted in detail. |
