摘要

城市道路可以被指定为地面洪水通道,在极端风暴期间运输多余的径流,从而防止局部洪水,这被称为主要排水系统。然而,由于道路的高流量和速度,这种做法带来了重大风险,包括人员损失和财产损失。此外,城市道路的抗洪能力较低,严重阻碍了城市在特大暴雨期间的交通功能,导致城市功能失调。因此,迫切需要将以风险为导向的洪水通道转变为具有弹性的城市道路洪水通道。本文系统地回顾了设计基于道路网络的洪水通道系统的现有方法,并讨论了增强系统弹性的新技术。该研究还解决了当前的知识差距和未来的方向。研究结果表明,基于城市道路网络的洪水管理措施应将可达性评价、生命线规划和应急规划相结合,以确保人类福祉。此外,在规划阶段必须认真考虑到脆弱群体的特殊需要和特点。此外,建议采用数据驱动的方法来促进实时管理和评估未来的工作。

From risk control to resilience: developments and trends of urban roads designed as surface flood passages to cope with extreme storms

From risk control to resilience: developments and trends of urban roads designed as surface flood passages to cope with extreme storms

Urban roads can be designated as surface flood passages to transport excess runoff during extreme storms, thereby preventing local flooding, which is known as the major drainage system. However, this practice poses significant risks, including human loss and property damage, due to the high flow rate and velocity carried by roads. Moreover, urban roads with low flood-resilience may significantly hamper the transportation function during severe storms, leading to dysfunction of the city. Therefore, there is an urgent need to transform risk-oriented flood passages into resilient urban road-based flood passages. This paper presents a systematic review of existing methodologies in designing a road network-based flood passage system, along with the discussion of new technologies to enhance system resilience. The study also addresses current knowledge gaps and future directions. The results indicate that flood management measures based on the urban road network should integrate accessibility assessment, lifeline and emergency planning to ensure human well-being outcomes. Furthermore, the special needs and features of vulnerable groups must be taken into serious consideration during the planning stage. In addition, a data-driven approach is recommended to facilitate real-time management and evaluate future works.

期刊介绍: Frontiers of Environmental Science & Engineering (FESE) is an international journal for researchers interested in a wide range of environmental disciplines. The journal''s aim is to advance and disseminate knowledge in all main branches of environmental science & engineering. The journal emphasizes papers in developing fields, as well as papers showing the interaction between environmental disciplines and other disciplines. FESE is a bi-monthly journal. Its peer-reviewed contents consist of a broad blend of reviews, research papers, policy analyses, short communications, and opinions. Nonscheduled “special issue” and "hot topic", including a review article followed by a couple of related research articles, are organized to publish novel contributions and breaking results on all aspects of environmental field.
