A GeoAI-Driven and Decision-Oriented Methodology for Multi-Hazard Early Warning System Development
Multi‐hazard early warning systems (MHEWS) are widely recognized as one of the most cost‐effective measures for disaster risk reduction and climate adaptation to date. However, intelligent solutions that can dynamically adapt to the heterogeneous disaster risk and impact information requirements of multi‐departmental stakeholders remain scarce. To facilitate a shift from quantity expansion to quality optimization, this study proposed a methodolog…
Critical node failure, impact and recovery strategy for metro network under extreme flooding in Shanghai
Scenario-based flood adaption of a fast-developing delta city
The economic impacts of flood-driven transportation delays
Cost-benefit analysis of local knowledge-based flood adaptation measures
Spatiotemporal Variations in Shanghai Metro Commuting Flows during Rainfall Events
Driven by both climate change and urbanization, extreme rainfall events are becoming more frequent and having an increasing impact on urban commuting. Using hourly rainfall data and “metro” origin–destination (OD) flow data in Shanghai, China, this study uses the Prophet time series model to calculate the predicted commuting flows during rainfall events and then quantifies the spatiotemporal variations of commuting flows due to rainfall at statio…
A spatial accessibility assessment of urban tourist attractions emergency response in Shanghai
Spatial Allocation Method of Evacuation Guiders in Urban Open Public Spaces
Evacuation guiders play an important role when emergency events occur in urban open public spaces. Considering the shortcomings of the existing studies, an optimization method based on the Particle Swarm Optimization (PSO) algorithm and gradual covering model for spatial allocation of evacuation guiders in urban open public spaces is proposed. This method considers the impact of obstacles on intervisibility between guiders and evacuees, and the n…
Spatiotemporal changes of manufacturing firms in the flood prone Yangtze Delta
Manufacturing firms in flood prone areas (FPAs) are a vital component of flood exposure, driving the non-stationarity of flood risks. This paper explores the spatiotemporal patterns of manufacturing firms in the FPAs of Yangtze Delta in China during 1998-2013. It is found that the number of firms in the FPAs increases remarkably by 44,385, with an annual growth rate of 10.2%. Established firms are located much closer to water bodies, mainly agglo…
Policy delivery gaps in the land-based flood risk management in China
Hard or soft flood adaptation? Advantages of a hybrid strategy for Shanghai
Flood risk is expected to increase in coastal cities, particularly in Asian megacities such as Shanghai. This paper presents an integrated modeling framework to simulate changes in the flood risk in Shanghai and provide a cost-benefit analysis of multiple adaptation strategies used to reduce risk. The results show that the potential flood risk will increase dramatically as a result of sea level rise, land subsidence, and socioeconomic development…
Mapping the capacity of concave green land in mitigating urban pluvial floods and its beneficiaries
Pre-evacuation Time Estimation Based Emergency Evacuation Simulation in Urban Residential Communities
The timely and secure evacuation of an urban residential community is crucial to residents' safety when emergency events happen. This is different to evacuation of office spaces or schools, emergency evacuation in residential communities must consider the pre-evacuation time. The importance of estimating evacuation time components has been recognized for approximately 40 years. However, pre-evacuation time is rarely discussed in previous communit…
A hierarchical pattern of urban social vulnerability in Shanghai, China and its implications for risk management
Rapid Population Growth in Chinese Floodplains from 1990 to 2015
Although China suffers from frequent and disastrous floods, the spatiotemporal pattern of its population living in the floodplain (PopF) is still unknown. This strongly limits our understanding of flood risk and the effectiveness of mitigation efforts. Here we present the first quantification of Chinese PopF and its dynamics, based on newly-available population datasets for years 1990, 2000, 2010, and 2015 and on a flood map. We found that the Po…
