城市洪涝试验研究进展

城市洪涝物理试验与原型试验是开展数值模型验证及提高预报预警精度的重要手段。从城市产流过程、地表洪水演进以及地表径流与管网水流交互三方面,综述了近年来国内外城市洪涝试验的研究进展。针对目前城市洪涝试验研究中存在的不足,指出今后应完善现有城市产汇流过程相关机理方面的试验研究,深入研究地表与管网垂向交互过程,加强与城市洪涝期间的流动行为密切相关过程的定量试验研究。

Advances in experimental research of urban flooding

Laboratory experiments and field tests of urban flooding are important approaches for model validation to improve the accuracy of simulation results. Advances in the research of urban flood characteristics by laboratory experiments were reviewed in three aspects, including the urban runoff generation process, the surface flood evolution, and the interaction of surface runoff with pipe network flow. Aiming at the shortcomings in the current study, it is necessary to improve the research on the mechanism of the surface runoff process through physical experiments and to intensify the research on the vertical interaction process between surface and pipe network flow. Quantitative experimental research on the associated processes closely intertwined with flow behavior during urban flooding should be strengthened.
