Abstract
This study proposes an innovative framework for mapping absolute flood resilience potential in socio-hydrological units of the Sang Sefid region, Iran, by integrating theoretical benchmark alternatives into a TOPSIS-based assessment. Using a dual-scale approach (relative and absolute), managerial-institutional flood resilience was assessed through 16 expert-validated indicators across five dimensions: institutional collaboration, education and awareness, performance and public satisfaction, prevention and reconstruction, and participatory planning. Data were collected via Likert-scale surveys from 663 household heads, with questionnaire reliability confirmed (α = 0.768). Resilience was quantified using TOPSIS with hypothetical minimum/maximum scenarios as benchmarks. Results revealed significant spatial variability: relative resilience ranged from very low (S-int3, R=0.00) to very high (S9, R=0.99), while absolute resilience ranged from very low (S-int3, R=0.05) to high (S9, R=0.75) with no "very high" category, highlighting critical distinctions between the two approaches. Model validation through Receiver Operating Characteristic (ROC) curve analysis (AUC = 0.917) and Cronbach's alpha (α = 0.857) confirmed outstanding performance and reliability. This framework enables systematic intra- and inter-regional resilience comparisons and temporal monitoring, serving as a replicable tool for multi-scale mapping to enhance adaptive governance and sustainable flood management in socio-hydrological systems.
