“…The literature review reveals a comprehensive understanding of the associated vulnerabilities and consequences of flooding events. Influencing factors include the force of floodwaters (Gokhale and Rahman, 2008;Hans Olav Heggen, 2014;Ferris et al, 2015;Huang et al, 2021;Bainbridge, 2023), soil erosion (Merz et al, 2007;Kreibich et al, 2009;Matthews and Matthews, 2013;Pistrika et al, 2014;Nofal & Van De Lindt, 2022;Rossi et al, 2022;Othman et al, 2023), and the intensity of floods/hurricanes (Bian et al, 2023;Rodell and Li, 2023). Techniques for assessing damage involve a combination of field inspections (Lai et al, 2017), remote sensing technologies (Forsyth et al, 2018), and data analysis (Taha et al, 2020a;Iqbal et al, 2021;Radovanović et al, 2022).…”

“…Flow velocity is one of the parameters that greatly influenced severity of flood damage (Merz et al, 2007;Kreibich et al, 2009;Pistrika et al, 2014;Nofal & Van De Lindt, 2022). High-velocity floodwaters can erode soil and damage pipelines, in which the high flow causing scour of the bed, erosion of the banks and, in some cases, the formation of a new channel (avulsion) (Matthews and Matthews, 2013;Rossi et al, 2022;Othman et al, 2023). After a pipeline has been exposed by scouring, it's vulnerable to the impact from passing debris, particularly during times when there is a highvelocity flow.…”

This review delves into the profound implications of flooding events on buried infrastructures, specifically pipelines, tunnels, and culverts. While these buried infrastructures are vital for community resilience, their susceptibility to damage from flooding, storm surges, and hurricanes poses significant challenges. Unlike the obvious impact on above-ground structures, the effects of flooding on buried infrastructures, being out of sight, are not quickly and easily observable. This review aims to 1) review the state-of-the-art research on the flooding effects on buried structures and summarize causes of failures of buried infrastructures induced by flooding; 2) identify the research gaps on this topic to motivate in-depth investigations; and 3) discuss the future research directions. This review sheds light on how factors contributing to the vulnerability of buried infrastructures are multifaceted and can vary based on the specific characteristics of the infrastructure, the local environment, and the nature of the flood event. Despite the availability of many articles on the topic, this review also highlights a lack of methodologies to assess flooding damage and its impact on the serviceability of buried infrastructures. We suggested three future research directions to bridge this research gap including investigating and distinguishing key factors to quantify flooding damage to buried infrastructures, developing advanced modeling techniques, and exploring the integration of smart technologies in health monitoring of buried infrastructures.

“…This kind of natural disaster gives the last ultimatum for governments to tackle the negative impact of climate change. Throughout the last few years, Japan has witnessed an increase in rainfall rate while many other countries, such as Pakistan, Afghanistan, and Saudi Arabia, have experienced unprecedented scale of flash floods [1][2][3]. Yet this crisis has been leaving individuals with irreplaceable loss of lives and possessions.…”

Climate change represents an overwhelming challenge that demands urgent intervention for effective resolution. Among the devastating consequences of climate change, flash floods stand out as one of the most catastrophic repercussions. This research focuses on two primary objectives. Firstly, it aims to evaluate the existing state of flash flood intensity (FFI) in a specific area of Hamamatsu city, Japan, which frequently experiences flash flood incidents. Secondly, it seeks to develop a mitigation plan to alleviate the adverse impacts of flooding on buildings within the area. To accomplish these objectives, four parameters related to FFI (namely, runoff depth, runoff velocity, runoff duration, and affected portion) were selected and estimated through the implementation of hydrological and hydrodynamic models. Additionally, a hydrological model was employed, utilizing a storm event with a return period of 100 years as input. During this simulated storm event, FFI values were calculated and categorized into four distinct levels. The results revealed that more than one-tenth of the examined buildings encountered the highest scale of FFI (category 4), while categories 3 and 4 combined accounted for nearly three-quarters of all buildings in the study area. Moreover, two mitigation strategies were adopted to prevent flooding within the buildings’ vicinity. Finally, this study provides a valuable framework and guidance for decision-makers and insurance companies, enabling them to assess the flood hazard status of buildings and make informed decisions accordingly.

“…In China, a megacity refers to a city with a population of over 10 million and is typically characterized by high levels of urbanization, industrialization, and economic development [30,31]. Megacities face many soil environmental issues, such as soil pollution [32], soil degradation [33,34], and soil erosion [35]. These issues not only affect the ecosystem services of the city but also threaten the health and quality of life of urban residents.…”

In the context of increasing urbanization and worsening environmental pollution, nonpoint source pollution during high-frequency rainfall has become a major ecological problem that endangers residents in cities. This study takes Shenzhen as an example. On the basis of a large number of soil sample test data, and combined with relevant environmental variables, it has drawn the high-resolution, high-precision spatial distribution maps of soil attributes within the city. In addition, this paper combines the revised universal soil loss equation and the GeoDetector model to evaluate the supply capacity of nonpoint source reduction services in the city’s ecological space and the main driving factors of spatial distribution characteristics for different types of land. The study found that increasing soil point density and combining environmental variables can help improve the accuracy of spatial mapping for soil attributes. The ME, MSE, ASE, RMSE, and RMSSE of spatial mapping all meet the accuracy evaluation criteria and are better than many existing studies; the spatial distribution characteristics of soil attributes and nonpoint source reduction services show significant differences among the whole city, secondary administrative regions, and different types of land; the GeoDetector results show that among the three main types of land use (forested land, industrial land, and street town residential land), topographic factors, habitat-quality factors, and ecosystem types have the greatest impact on the spatial differentiation characteristics of nonpoint source reduction services. Among climate factors, only precipitation factors have the greatest impact on the spatial differentiation characteristics of services. Facing the above factors, the q-values calculated by the GeoDetector are all higher than 10%. The results of this study can provide information for making better decisions on regional ecological system management and soil protection and on restoration work aimed at improving nonpoint source reduction services.
