Assessing Flash Flood Susceptibility in Watersheds Using AHP and ANP Approaches (Case Study: Southern Halqeh Darreh)

This study assessed flash flood susceptibility in ۱۳ sub-watersheds of the Southern Halqeh Darreh, Alborz Province, using AHP and ANP. Physiographic factors like slope, drainage density, and mean elevation were weighted by experts using Super Decision and mapped in ArcGIS. AHP identified slope as most influential (۰.۳۶۲۴۷), while ANP prioritized drainage density (۰.۳۷۸۱۲). Consistency ratios were acceptable. AHP showed sub-watershed ۸ (۹۴.۵۱۳ ha) as highest risk, whereas ANP identified sub-watershed ۹ (۳۴.۲۷۳ ha). This highlights ANP's value in modeling factor interdependencies. Findings can guide targeted watershed management.
