摘要
在城市化的快速发展和极端暴雨天气频发背景下,世界很多城市遭遇暴雨内涝侵袭。而城市洪水模拟计算呈现出计算范围大、模拟精度高等特点,对模型要求越来越高。本文选取英国伦敦为研究区域,采用基于细胞自动机的二维洪水模型CADDIES-2D进行洪水模拟,并采用基于情景模拟的方法评估了伦敦Waterloo区域洪水风险。结果表明,基于细胞自动机的二维洪水模型CADDIES-2D计算效率高,具有较高的实用性和有效性,可用于城市洪水风险分析,提高城市防灾减灾水平。
In the context of rapid development of urbanization and frequent extreme rainstorm, many cities of the world experienced heavy and extreme rainfall flooding. Urban flood modelling presents the characteristics of large extent with high resolution and needs accurate flood simulation model. London（UK） is chosen as the study area. A Cellular Automata based model CADDIES-2 D is used to simulate megacity surface water flood inundation. The flood risk of Waterloo（London） is evaluated based on the scenario simulation method. Results show that the calculation efficiency of CADDIES 2 D is high. The model has high practicability and effectiveness, which can be used for urban flood risk analysis, improving urban disaster prevention and mitigation. Keywords
