What is Urban Flooding Risk Assessment?
Urban Flooding Risk Assessment evaluates pluvial flood hazards in cities from intense rainfall on impervious surfaces using coupled hydrodynamic models and vulnerability metrics.
Researchers model surface-subsurface interactions via shallow water equations and LSTM networks for rainfall-runoff prediction. Assessments integrate socio-economic vulnerability and economic damage functions. Over 50 papers since 2006 address urbanization-driven flood escalation, with key works exceeding 1200 citations.
Why It Matters
Urban flood risk assessment guides city planning in megacities facing rising pluvial events, informing blue-green infrastructure investments. Kundzewicz et al. (2013) document economic losses tripling due to asset exposure growth despite stable flood frequencies. Merz et al. (2010) provide damage estimation frameworks used in adaptation policies across Europe, while Bates et al. (2010) enable efficient inundation modeling for real-time urban emergency response.
Key Research Challenges
Coupled Hydrodynamic Modeling
Simulating urban pluvial floods requires integrating surface runoff with subsurface drainage under impervious surfaces. Bates et al. (2010) inertial shallow water formulations improve efficiency but struggle with high-resolution urban grids. Kratzert et al. (2018) LSTM models enhance rainfall-runoff accuracy yet demand extensive calibration data.
Socio-Economic Vulnerability Integration
Quantifying human exposure combines hazard maps with population demographics and behavior. Grothmann and Reußwig (2006) identify precaution gaps but scaling to city-wide risk remains inconsistent. Zscheischler et al. (2018) highlight compound event dependencies complicating vulnerability metrics.
Climate Change Projection Uncertainty
Projecting future urban flood risk under RCP scenarios faces rainfall intensity uncertainties. Arnell and Gosling (2014) model global river flood increases but urban pluvial specifics vary regionally. Winsemius et al. (2015) global drivers analysis reveals urbanization amplifying baseline climate risks.
