Abstract

The rise in urban flooding events poses a threat to public safety, property, and economic stability. To prevent urban flooding and manage stormwater effectively, relying solely on engineering solutions is insufficient. Therefore, it is critical to implement non-engineering measures such as urban flood warnings and forecasting. This article reviews the characteristics of different urban flood models based on different hydrological and hydrodynamic principles and deep learning (DL). It highlights the limitations of coupled hydrological-hydrodynamic models in terms of timeliness. Additionally, it discusses research on the use of Numerical Simulation in hydrological early warning and forecasting. Compared to traditional hydrodynamic models that rely on physical mechanisms, models driven by DL methods can effectively and adaptively extract input-output relationships of complex systems. Subsequently, a summary of the current flood models is presented, followed by a discussion of future development trends and challenges.

城市洪水模拟的研究进展与展望:从传统数值模型到深度学习方法
城市洪水事件的增加对公共安全、财产和经济稳定构成了威胁。要预防城市内涝并有效管理雨水,仅仅依靠工程解决方案是不够的。因此,实施城市洪水预警和预报等非工程措施至关重要。本文回顾了基于不同水文和流体力学原理以及深度学习(DL)的不同城市洪水模型的特点。文章强调了水文-流体力学耦合模型在时效性方面的局限性。此外,它还讨论了在水文预警和预报中使用数值模拟的研究。与依赖物理机制的传统水动力模型相比,由 DL 方法驱动的模型可以有效、自适应地提取复杂系统的输入-输出关系。随后,概述了当前的洪水模型,并讨论了未来的发展趋势和挑战。

期刊介绍: Environmental Modelling & Software publishes contributions, in the form of research articles, reviews and short communications, on recent advances in environmental modelling and/or software. The aim is to improve our capacity to represent, understand, predict or manage the behaviour of environmental systems at all practical scales, and to communicate those improvements to a wide scientific and professional audience.
