Urban Flood Risk Assessment Based on Dynamic Population Distribution ...

Floods are one of the most common natural disasters that can cause considerable economic damage and loss of life in many regions of the world. Urban flood risk assessment is important for urban flood control, disaster reduction, and risk management. In this study, a novel approach for assessing urban flood risk was proposed based on the dynamic population distribution , improved entropy weight ...

In this study, a novel approach for assessing urban flood risk was proposed based on the dynamic population distribution , improved entropy weight method, fuzzy comprehensive evaluation method, and the principle of maximum membership, and the spatial distribution of flood risk in four different sessions or daily time segments (TS1-TS4) in the ...

Urban Flood Risk Assessment Based on Dynamic Population Distribution ...
The results of the flood risk assessment based on the dynamic population distribution , combined weight method, fuzzy comprehensive evaluation method, and the principle of maximum membership in the study area are reported and discussed in Section 4.
Highlights • Dynamic flood risk assessment based on human activity in urban functional zones. • Indicators combine hydrodynamic modeling and multi-source population data. • Indicator weights integrated via IFAHP+EWM; multi-criteria ranking with TOPSIS. • Weekday-weekend flood risks compared at five times to show spatiotemporal change.

Urban pluvial flood risk assessment combining static and dynamic ...
The formation and impacts of urban pluvial flooding are complex and dynamic . Traditional pluvial flood risk assessments are primarily static, with limited focus on dynamic evaluations. Based on multi-source big data, this study integrates the advantages of both subjective and objective indicator weighting method and hydrodynamic modeling to perform static and dynamic flood risk assessments for ...
The interactions between flooding and dynamic population distribution is critical for the exposure assessment of urban flood disasters. This necessitates the integration of the social drivers of the human system and the natural drivers of the hydrological system as endogenous variables within the urban 'human-water' nexus [8].

A novel framework for urban flood risk assessment
Dense populations and assets contribute to high flood risk , while adaptive capacity significantly mitigates urban flood risk . The framework adopted in this paper can be applied to other areas where urban agglomeration-scale flood risk assessment is needed, and can contribute to advancing scientific research on flood forecasting and mitigation.
