本文采用改进的城市洪水模型，将二维非惯性坡面流模型与雨水管理模型相耦合，对城市洪水进行了模拟。该模型不仅计算了地表径流和地表径流超过雨水管容量的沙井溢流，而且还计算了雨水管和地表径流之间的双向流动相互作用。该模型已被2000年11月的一次台风事件所验证，该台风事件导致台北市木栅地区严重淹没。结果表明，该模型确实提高了模拟精度比以前的模型。并且可以用于提供更可靠的洪水缓解设计。
An improved urban inundation model, coupling a 2D non-inertia overland flow model with a storm water management model, is adopted to simulate inundation in urban areas. The model computes, not only the overland runoff and the water overflow through manholes where surface runoff exceeds the capacity of storm sewers, but also the bidirectional flow interactions between sewers and overland runoff. The model was verified by a typhoon event in Nov. 2000, which resulted in serious inundation in the Mucha area of Taipei City. The result shows that the present model indeed improves simulation accuracy over the earlier model. and can be used to provide a more reliable flood mitigation design.
