Abstract: 近年来,城市内涝问题日益突出,严重影响着城市的可持续发展。运用合肥市气象数据、地理信息数据、社会经济统计数据以及历史内涝灾情数据,基于二维非恒定流水动力模型(FloodArea),开展城市内涝灾害风险评估与预警技术研究。研究表明:根据城市内涝预警业务需求,综合暴雨强度公式和广义极值分布两种方法,推算出合肥市1、3、6、12、24 h下5、10、20、30、50、100 a一遇的降水量,应用FloodArea模型模拟得到不同历时下多个重现期的淹没水深图谱,耦合精细化的承灾体信息及脆弱性曲线,完成合肥市城市内涝风险评估,再结合强降水预报,开展城市内涝风险预警业务应用;由典型内涝过程的效果检验可知,风险评估结果与灾情调查数据较为吻合、可靠度高,进而建立了降水预报→淹没模拟→风险评估→预警发布→效果检验一套较为完备的城市内涝风险评估与预警业务流程,可用于城市内涝实时风险评估与预警业务。
