resilience and flexibility of cities against disasters

nowadays, increasing resilience in natural disasters has turned to an important field and todays synchronized movement and reciprocal of permanent development and disaster management is discussed toward increasing resilience. the resilience instead of prevention or decreasing the effects of damages and casualties resulting of natural disaster focuses on enhancing the operation of a system encountering with damages. in present study, the researchers study todays resistance and flexibility of urban area when encountering with natural disaster especially earthquakes and floods in iran and then offer some techniques about increasing urban’s resilience and resistance in front of natural disasters. this is a descriptive and analytical research. the results show that the effective planning and executive and correct steps has not been executed for decreasing dangers of flood and the amount of resilience in area where are flood plain in iran is at the minimum. also the studies show crisis management in resent earthquake isn’t very successful and only in recent years some steps in making resistant building and rebuilding old buildings and informing and teaching people has been done very slowly. so, the amount of the resistance in cities in iran when encountering with earthquake is at the minimum but this amount can be enhanced when encountering with flood and earthquake by planning and effective steps in the evaluation of safety of the substructures and rebuilding them, informing and preparing people and authorities, and also allocating financial source for old vulnerable areas and establishing some community-center groups. these steps also cause to decrease the amount damage in natural disaster.
