Vulnerability Assessment of Transport Network in Earthquake Conditions to Determine Alternative Water Supply Centers (Case Study: Hamadan City)

Earthquake as a natural phenomenon causes serious damage to humans. One of the most important measures before an earthquake is to be aware of the vulnerability of urban infrastructure. The transportation network as one of the main infrastructures of the city can help the water infrastructure in critical conditions and provide water supply to the people by transporting water by tanker to the water supply centers. What is needed here is to assess the vulnerability of the transport network to earthquakes in order to provide the necessary arrangements. The purpose of this study was to evaluate the vulnerability of Hamadan transportation network in terms of selected indicators and designation of alternative water supply centers. From the scientific methodological point of view, this research can be considered as a descriptive-analytical one where the descriptive data are collected through library studies and other field data are obtained through field operations. For this purpose, the vulnerability of the routes in each of the selected parameters (population density, age of the building, outdoor access, distance from the fault, etc.) was investigated and the overall vulnerability map derived from the integration of all the indicators in the transport routes. The water was obtained by paired comparison method and ArcGis software and finally, considering the water requirement of each area and the vulnerability of the waterways, the number of alternative water supply centers was determined, which for a 3 center area, two 5 center area, Area 3 has 3 centers and area 4 has 2 centers.
