1. 积涝的解释
1. 城市的快速发展带来了经济的繁荣，同时伴生出一系列的问题，其中城市暴雨洪水积涝灾害就是其重要问题之一。
The rapid development of cities brings about economic boom, but also associated with a series of problems, of which urban storm flood waterlogging is one.
2. 结果表明：积涝预警系统能很好地模拟由于强降水而造成的积涝情况，模拟的积水范围和深度与实况基本吻合。
The results showed that this system could simulate waterlog caused by heavy precipitation very well.
3. 中文关键词：数学模型，城市暴雨洪水积涝，非恒定流，有限单元法
Mathematical model, urban rainstorm flood waterlogging, unsteady flow, finite element method
4. 首先介绍了城市雨水径流及洪涝模型的基本理论及发展现状，其次详细推导了浅水二维非恒定流基本方程，同时介绍了运用有限元法建立二维水流数学模型的原理和步骤，最后在此基础上综合福州市大学新区的气象、水文、水力、排水等各方面的知识和资料，建立了大学新区暴雨洪水积涝数学模型。
Firstly, the basic theory and the present development situation of urban stormwater runoff and flood model are introduced. And then the basic equation of the shallow 2-d unsteady flow is deduced detailedly. In addition, it also presents the principle and procedure of the establishment of a mathematic 2-d flow model by the finite element method. Finally, along with the knowledge and data of meteorology, hydrology, hydraulics, drainage etc.
