【摘要】 城市化快速发展使得城市暴雨积涝多发。SWMM模型的发展和其在城市中的应用较为成熟,模型所包含的参数物理概念相对清晰。本研究探索在大比例尺、高分辨率的空间地理数据和GIS技术的支撑下,针对城市小区域进行暴雨积涝模拟的参数率定方法,并分析不同参数率定对模型模拟效果的影响,以期提高SWMM模型在城市小区域暴雨积涝应用的准确性。更多还原

【Abstract】 With the rapid development of urbanization,more and more urban rainstorm waterlogging has occurred.The development of SWMM model and its application in the city are more mature,and the physical concepts of parameters which the model contains are relatively clear.This study explores a method of parameter calibration for rainstorm waterlogging simulation in small urban areas under the support of large-scale,high-resolution spatial geographic data and GIS technology,and analyzes the influence of different parameter calibration on the simulation effect of the model to improve the accuracy of SWMM model applied to the rainstorm waterlogging in small urban areas.更多还原
