A Tri-System Urban Waterlogging Risk Assessment Framework Based on GIS- Game Theory Combination Weight: a Case of Zhengzhou City

The urban waterlogging risk is sensitive to complex interactions among spatially distributed H-E-V (Hazards, Exposure, and Vulnerability) factors and is affected by indicator weighting and risk calculation models. To investigate and relieve these sensitivities, a tri-system risk assessment framework is devised, consisting of indicator, griding, and risk assessment systems. The entropy, CRITIC, and game theory (GT) are integrated to weigh the fifteen indicators for the Zhengzhou City area. The risk assessment method based on GT and additive model achieved the best performance: (1) 90.39
