Climate change has significantly increased the risks associated with urban flooding. However, most research on flood risk assessment focuses large-scale climate changes and impacts, leaving a gap in high spatial resolution of inter-urban areas. This makes it difficult to guide regional planning for government. Therefore, this study aims explore floods ultra-high-density cities under at scale, using Hong Kong as case study. We comprehensively assessed index (FRI) built environment 211 tertiary units (TPUs) from three dimensions vulnerability, exposure, hazard 2006 2021. also employed prediction model forecast spatial–temporal patterns FRI next 5, 10, 15 years evaluated uneven distribution risks. The results show that TPUs yearly, which poses higher threats agglomerative areas transportation functional facilities. Additionally, future will further impact coastal western Kong, resulting more negative impacts high-building should prioritize integrating management mitigation measures.

The frequent urban floods have seriously affected the regional sustainable development in recent years. It is significant to understand characteristics of flood risk and reasonably predict under different land use scenarios. This study used random forest multi-criteria decision analysis models assess spatiotemporal Zhengzhou City, China, from 2005 2020, proposed a robust method coupling Bayesian network patch-generating simulation future probability. We found that City presented an upward trend its spatial pattern was "high middle low surrounding areas". In addition, patterns scenario would be more conducive reducing risk. Our results can provide theoretical support for scientifically optimizing improve management.

Coastal regions, increasingly threatened by floods due to climate-change-driven extreme weather, lack a comprehensive study that integrates coastal and riverine flood dynamics. In response this research gap, we conducted bibliometric analysis thorough visualization mapping of studies compound flooding risk in cities over the period 2014–2022, using VOSviewer CiteSpace analyze 407 publications Web Science Core Collection database. The analytical results reveal two persistent topics: way explore return periods or joint probabilities drivers statistical modeling, quantification with different through numerical simulation. This article examines critical causes flooding, outlines principal methodologies, details each method’s features, compares their strengths, limitations, uncertainties. paper advocates for an integrated approach encompassing climate change, ocean–land systems, topography, human activity, land use, hazard chains enhance our understanding mechanisms. includes adopting Earth system modeling framework holistic coupling components, merging process-based data-driven models, enhancing model grid resolution, refining dynamical frameworks, comparing complex physical models more straightforward methods, exploring advanced data assimilation, machine learning, quasi-real-time forecasting researchers emergency responders.

Against the backdrop of global warming and rising sea levels coupled with increasing urbanization, flood risks for plain cities have intensified. This study takes Liaocheng City as its research object constructs a regional risk assessment model based on combination subjective objective multi-weight methods. The sets weights according to different return periods from three perspectives: severity disaster-causing factors, exposure disaster-prone environments, vulnerability disaster-bearing bodies. It also uses subjective–objective adopts CRITIC-entropy environments bodies, AHP criterion layer. Based GIS spatial analysis technology, examination zoning disasters at county scale were carried out. results show that, unlike existing weighting methods machine learning methods, this method can simultaneously avoid subjectivity uncertainty parameters, thus enabling more accurate decision-making be obtained. distribution comprehensive is high in central western parts relatively low south north, while area characterized by very concentrated Dongchangfu District Guanxian County. With gradual increase periods, overall medium-to-very-high-risk areas gradually shrinks, very-high-risk moves but maintains stable rule. Flood an important basic process disaster prevention mitigation cities, provide reference similar cities.
