【摘要】 “北江大堤洪水风险信息管理系统”中洪水仿真模型的研究， 是根据北江大堤可能出现的溃堤风险，模拟了北江大堤溃决后保护区内洪水的演进过程，模型的计算结果提供的淹没水深、淹没范围、淹没历时以及流速等洪水风险信息， 为北江大堤洪水风险图的绘制提供了依据更多还原

【Abstract】 A Flood Simulation Model as a part of Flood Risk Information System in Beijiang Area is developed. Based on flood risk analysis in Beijiang area, the model si mulates the flooding process caused by dam break in guard district. The modeling results of flood risk information, such as submerged depth, flooded area, duration of flood and flow speed provide basis for Flood Risk Mapping of Beijiang Area.更多还原
