Passive Defense Considerations in the Site Location of Reservoir Dams Using the AHP Method

The qualitative and quantitative planning of a site requires comprehensive information about technical, economic, defense, social and environmental factors on a large scale. Nowadays, the countries which have experienced damages caused by disasters, pay particular attention to passive defense in order to preserve national assets and have placed a special position in their defense strategy. It is certain that the selection of the best location is always considered as passive defense important issue, such that the existing potentials can be placed in line with the principles of passive defense and the lack of these capabilities causes irreparable damages to the achievement of passive defense objectives. Hence, identifying and investigating the indexes and criteria of optimum site selection are an inevitable necessity. On the other hand, safeguarding and providing water as a vital element through establishing dams, is necessary. This research is intended to minimize damages, possible impacts and also to precisely identify threats through identifying and ranking passive defense indexes affecting site location of reservoir dams. The necessary information was gathered through designing and filling out even comparison questionnaires which was collected by industry experts and managers and this information was extracted and analyzed through utilizing the Analytical Hierarchy Process in the Expert Choice software. The results indicate that among passive defense indexes, issues such as "security", "deterrence", "safety", "simplicity of risk and crisis management (natural and man-made disasters)", "leakage and water blockage", "earthquake", "reconstruction", "dam rupture" are respectively on the main priority of the site location of reservoir dams with weight coefficient of 0.038, 0.039, 0.040, 0.041, 0.064, 0.167, 0.226, 0.385.
