Abstract :

Evaluating the vulnerability of cities to wars and crises and devising appropriate solutions to reduce losses is essential. Therefore, this study seeks to assess and map the vulnerability of Chalus from a passive defense perspective. This study was a descriptive survey of purpose, field, field, nature, method and type of survey. It was initially collected through bibliographic and field studies and satellite imagery. After examining land uses in Chalus City, they were classified into 5 categories including critical arteries, crisis management centers, urban facilities, military facilities, and support centers. , Land uses were extracted on a case-by-case basis for the purpose of providing a spatial database. Each layer has a different effect on increasing or decreasing vulnerability due to the proximity of the adjacent spatial standard and their relative distance to critical and passive defense applications. For each layer relative to critical and sensitive applications in terms of passive defense, security is defined and so-called spatial distance maps are drawn. Finally, the vulnerability mapping of the area was prepared according to the passive defense principles.According to the obtained figure, Chalus city is divided into three zones that are similar in vulnerability to passive defense approach. The results of the study show that the central urban areas are the most vulnerable areas of the city.
