Waterlogging Risk Assessment of Airport Airfield Areas Using the Analytic Network Process with Triangular Fuzzy Numbers

open access: yesWater
Risk assessment is an effective management tool for mitigating waterlogging disasters. In this study, a novel airport waterlogging risk assessment framework based on the analytic network process with triangular fuzzy numbers (TFN-ANP) was developed to evaluate hazard, exposure, vulnerability, and comprehensive risk under different return periods.
