城市集水区分析工具-CityCAT-是一种新颖的软件系统，用于快速评估组合洪泛和河流洪水风险，使用独特的组合：高效的软件架构，特别是在数值部分;使用标准的，现成的数据集;高效的网格生成算法;和强大的和准确的流量方程的解决方案。它是基于先进的软件架构和精确的解决方案，复杂的自由表面流动的地形之间的渗透性和不可渗透的表面区分，并考虑到人为特征的影响，如建筑物作为流动的障碍。该软件首先通过基于分析解决方案和实验室研究的苛刻测试用例进行严格验证。然后，在大型城市领域，如屋顶存储的建筑物或引入可渗透表面的特定防洪干预措施的有效性评估的独特能力，证明。
City Catchment Analysis Tool-CityCAT-is a novel software system for rapid assessment of combined pluvial and fluvial flood risk using a unique combination of: efficient software architecture throughout and especially in the numerical part; use of standard, readily available data sets; efficient algorithms for grid generation; and robust and accurate solutions of the flow equations. It is based on advanced software architecture and accurate solutions for complex free-surface flow over the terrain distinguishing between permeable and impermeable surfaces and taking into account effects of man-made features such as buildings as obstacles to flow. The software is firstly rigorously validated with demanding test cases based on analytical solutions and laboratory studies. Then the unique capability for assessment of the effectiveness of specific flood alleviation interventions across large urban domains, such as roof storage on buildings or introduction of permeable surfaces, is demonstrated.
