Evaluation of physical resilience indices in Sari using Inversion Hierarchy Weighed Process (IHWP) model

In recent years, the unprecedented growth of population and the enormous damage caused by natural and human hazards to the physical and urban environment has made resilience an important topic in natural hazard studies. In the present study, evaluation of resilience of Sari city with emphasis on physical dimension by using Reverse Hierarchical Analysis (IHWP) model using eleven physical indicators such as road width, access to green and open spaces, access to multipurpose spaces, distance from worn-out tissue, and so on. The statistical sample of the study was 48 experts in urban planning and crisis management in the form of Delphi questionnaire. The outputs of the questionnaire modeled in GIS software and the final physical resiliency map of Sari produced. The results show that 50% of city area has low and very low resiliency, 19% moderate and 31% high and very high; and resiliency increased from west to east, and the northwest and northeast parts of the city are less resilient. Finally, some suggestions made to improve resilience.
