摘要
城市洪涝模拟是当前国内外城市防洪减灾领域研究的热点。现有城市洪涝模拟方面的评述,主要依据城市洪涝过程或模拟计算方法进行分类讨论,缺乏基于应用需求的视角。随着应用需求日益深入,城市洪涝模拟应用场景日趋多样化和复杂化,不同模拟应用场景下,所关注的洪涝过程不同,采用的技术策略及其重点和难点也不同,脱离模拟应用场景很难辨析这些不同。依据模拟对象和关注变量,归纳总结出城市洪涝模拟的3种典型应用场景,即城市外洪模拟、城市雨洪模拟、城市内涝模拟;针对这3种典型模拟应用场景,分析相应的城市洪水演进模型、城市雨洪模型、半分布式暴雨内涝模型、全分布式暴雨内涝模型等4类模拟技术策略;辨析在不同模拟应用场景和技术策略下,不同模拟技术的组合方式及其特点与难点,以期从应用需求的角度对城市洪涝模拟技术进行全面的梳理,为城市洪涝模拟应用和研究提供一个新的视角。
