Urban Flood

Urban floods research has been attracting extensive attention with the increasing threat of flood risk and environmental hazards due to global climate change and urbanization. However, there is rarely a comprehensive review of this field and it remains unclear how the research topics on urban floods have evolved. In this study, we analyzed the development of urban floods research and explored the hotspots and frontiers of this field by scientific knowledge mapping. In total, 3314 published articles from 2006 to 2021 were analyzed. The results suggest that the number of published articles in the field of urban floods generally has an upward trend year by year, and the research focus has shifted from exploring hydrological processes to adopting advanced management measures to solve urban flood problems. Moreover, urban stormwater management and low impact development in the context of climate change and urbanization have gradually become research hotspots. Future research directions based on the status and trends of the urban floods field were also discussed. This research can not only inspire other researchers and policymakers, but also demonstrates the effectiveness of scientific knowledge mapping analysis by the use of the software CiteSpace and VOSviewer.

The link between climate change and conflict has been discussed intensively in academic literature during the past decade. This review aims to provide a clearer picture of what the research community currently has to say with regard to this nexus. It finds that the literature has not detected a robust and general effect linking climate to conflict onset. Substantial agreement exists that climatic changes contribute to conflict under some conditions and through certain pathways. In particular, the literature shows that climatic conditions breed conflict in fertile grounds: in regions dependent on agriculture and in combination and interaction with other socioeconomic and political factors such as a low level of economic development and political marginalization. Future research should continue to investigate how climatic changes interact with and/or are conditioned by socioeconomic, political, and demographic settings to cause conflict and uncover the causal mechanisms that link these two phenomena.

The Pearl River

<p>The Pearl River Basin (PRB), as the second largest basin in China and one of the densely populated areas in China, is a critical region that exposes to high flood risks. Thus, it is indispensable to monitor the flooding patterns in PRB, so as to understand the flooding mechanism and better respond to the flood hazards. Previous studies about flood monitoring in PRB were mainly conducted by using gauging data of hydrological stations. However, the flood monitoring results would be prone to deviation in the region where the hydrological stations were sparse or without hydrological stations. Moreover, previous studies mainly focused on the urban flood in metropolis in PRB, neglecting the flood extents in rural area, in which the agriculture lands were constantly inundated by flooding water body. To monitor flood more comprehensively, this study will combine hydrological data, precipitation data with Sentinel-1 images to investigate spatial patterns of flood peak and flood extents in PRB. In addition, this study will also combine flood extents with land cover map to calculate the inundated areas of cropland during flood periods. This study will be valuable for flood mitigation, flood prevention and food guarantee in PRB.</p>

Image Capturing

With the increase of extreme weather events, the frequency and severity of urban flood events in the world are increasing drastically. Therefore, this study develops ARMT (automatic combined ground weather radar and CCTV (Closed Circuit Television System) images for real-time flood monitoring), which integrates real-time ground radar echo images and automatically estimates a rainfall hotspot according to the cloud intensity. Furthermore, ARMT combines CCTV image capturing, analysis, and Fourier processing, identification, water level estimation, and data transmission to provide real-time warning information. Furthermore, the hydrograph data can serve as references for relevant disaster prevention, and response personnel may take advantage of them and make judgements based on them. The ARMT was tested through historical data input, which showed its reliability to be between 83% to 92%. In addition, when applied to real-time monitoring and analysis (e.g., typhoon), it had a reliability of 79% to 93%. With the technology providing information about both images and quantified water levels in flood monitoring, decision makers can quickly better understand the on-site situation so as to make an evacuation decision before the flood disaster occurs as well as discuss appropriate mitigation measures after the disaster to reduce the adverse effects that flooding poses on urban areas.

Empirical Material

This Special Issue aims to further understanding and explanation of the funding, financing and governing of urban infrastructure amidst its engagements with contemporary financialisation. Drawing upon empirical material from international cases from Europe, North America, Africa and Asia, it identifies critical issues to advance work in this area. These themes concern: the impacts of financialisation upon shifting the definitions and conceptualisations of urban infrastructure; the worth of adopting more actor-oriented and grounded approaches to financialisation; the importance of affording greater recognition to national and local states as the objects and agents of financialising relations, processes and practices; the substance and ramifications of the emergent informalisation of infrastructure policy-making and governance; and, the implications of financialisation for the evolving and uneven landscapes of urban infrastructure provision. The arguments are, first, that how infrastructure is funded, financed and governed is integral to explaining socially and spatially uneven infrastructural provision and its urban development ramifications; and second, the engagements of urban infrastructure with contemporary financialisation have become central in such accounts. Future research avenues are identified. These comprise: identifying exactly how revenues are generated from infrastructure assets; specifying the relations of financialisation with other processes such as ‘assetisation’, ‘marketisation’ and privatisation; extending the geographical and comparative reach of current studies; elaborating the spaces of regulation in negotiating and accommodating infrastructure financialisation; and, scrutinising the roles of decentralised powers and resources in financialising urban infrastructure and exploring its alternatives.

Abstract. This article presents a novel methodology to assess flood risk to people by integrating people's vulnerability and ability to cushion hazards through coping and adapting. The proposed approach extends traditional risk assessments beyond material damages; complements quantitative and semi-quantitative data with subjective and local knowledge, improving the use of commonly available information; and produces estimates of model uncertainty by providing probability distributions for all of its outputs. Flood risk to people is modeled using a spatially explicit Bayesian network model calibrated on expert opinion. Risk is assessed in terms of (1) likelihood of non-fatal physical injury, (2) likelihood of post-traumatic stress disorder and (3) likelihood of death. The study area covers the lower part of the Sihl valley (Switzerland) including the city of Zurich. The model is used to estimate the effect of improving an existing early warning system, taking into account the reliability, lead time and scope (i.e., coverage of people reached by the warning). Model results indicate that the potential benefits of an improved early warning in terms of avoided human impacts are particularly relevant in case of a major flood event.

Floods are amongst the most common and devastating of all natural hazards. The alarming number of flood-related deaths and financial losses suffered annually across the world call for improved response to flood risks. Interestingly, the last decade has presented great opportunities with a series of scholarly activities exploring how camera images and wireless sensor data from Internet-of-Things (IoT) networks can improve flood management. This paper presents a systematic review of the literature regarding IoT-based sensors and computer vision applications in flood monitoring and mapping. The paper contributes by highlighting the main computer vision techniques and IoT sensor approaches utilised in the literature for real-time flood monitoring, flood modelling, mapping and early warning systems including the estimation of water level. The paper further contributes by providing recommendations for future research. In particular, the study recommends ways in which computer vision and IoT sensor techniques can be harnessed to better monitor and manage coastal lagoons—an aspect that is under-explored in the literature.
