| This study employs the Analytic Hierarchy Process (AHP) to assess the vulnerability and resilience of the urban water distribution network in the Feyzabad and Baharan districts of Sanandaj against the parameter of Peak Ground Velocity (PGV). The main objective is to identify the key factors influencing network vulnerability and to propose strategies for enhancing the resilience of this critical infrastructure. PGV values were derived based on data from 40 faults longer than 10 km within a 70 km radius of the city, using empirical attenuation relationships. Geological, geomorphological, soil type, and pipe diameter and material data were collected from reliable local sources.In the AHP model, the main criteria including PGV, geology, soil, pipe material, and pipe diameter were integrated with weights of 0.460, 0.112, 0.243, and 0.182, respectively, and vulnerability maps of the network were generated. Results showed that PGV values across the city range between 35 and 39 cm/s. In Feyzabad, lower PGV values combined with thick steel pipes and Quaternary alluvial soils resulted in 81% of the network falling into the low-vulnerability class and only 2.1% into the high-vulnerability class. Conversely, in Baharan, higher PGV values (39 cm/s), combined with small-diameter asbestos pipes and shale bedrock, placed 34% of the network in the very high-vulnerability class. |
