Available data relating to major pluvial flooding events in Jakarta, Indonesia were used to investigate the suitability of two different levels of sophistication in urban modelling tools for modelling these events. InfoWorks CS v9.0 was employed to build 1D and 1D/2D models of a 541 ha area of inner city Ciliwung River catchment which has a history of being particularly badly affected by flooding during heavy rainfall events. The study demonstrated that a 1D model was sufficient to simulate the flood extent of a major event using the limited data available. While the 1D/2D model also performed well, more data and time would have been required to match the 1D model's simulation of flood extent. Much more detailed data would have been required to produce reliable results in the 1D/2D model and to enable any kind of verification or calibration of the two models beyond visual comparison with crude flood extent maps.
利用与印度尼西亚雅加达重大暴雨洪水事件相关的数据,研究了两种不同复杂程度的城市建模工具在模拟这些事件方面的适用性。InfoWorks CS v9.0 用于构建内城 Ciliwung 河流域 541 公顷面积的 1D 和 1D/2D 模型,该流域历史上在暴雨事件中特别容易受到洪水影响。研究表明,使用有限的数据,1D 模型足以模拟重大事件的洪水范围。虽然 1D/2D 模型也表现良好,但要匹配 1D 模型的洪水范围模拟,需要更多的数据和时间。需要更详细的数据才能在 1D/2D 模型中获得可靠的结果,并能够对两个模型进行任何形式的验证或校准,而不仅仅是与粗略的洪水范围图进行视觉比较。
