Climate change is increasing flood risks in urban areas, with heavy rainfall disasters now becoming a global problem. Numerical simulations predict flooding from heavy rain and river overflows, usually displaying results on flat maps. However, map scale can limit detailed risk assessment, making it difficult for residents to fully understand flood risks.
