Overview

Automated evaluation calculates waterlogging depth and building losses in urban pluvial scenarios, indicating substantial financial risks.

Key Points

  • Economic losses from waterlogging reached approximately USD 327.88 million in Jinan City, with residential buildings suffering the most.
  • The methodology achieved a mean absolute percentage error within 5% for both residential and commercial building assessments.
  • The proposed framework integrates GIS-based modeling to enable precise estimation of waterlogging depth and consequent damage assessments.
  • This framework supports other high-density urban areas by applying rainfall scenarios and high-resolution elevation models for localized damage evaluation.
