Like any other country, Iran is jeopardized by many environmental hazard threats and such threats can culminate in environmental disasters with tremendous repercussions such as loss of people’s lives, destruction of national assets, disruption of man-made building, dangers threatening mass population, etc. To stand against this, approaches in hazard management are after finding more pragmatic solution for these repercussions. Moreover, these hazards are associated with desertification, tectonic, cycles of aridity and surface processes associated with wind and water erosion. This paper provides information on the threats and vulnerability imposed on Zayandeh- Roud Basin (Z.R.B, hereafter) in Iran. For this aim, assessment was carried out by overlaying hazards map, human variable, and adaptation capacity map. Results are in the form of classification vulnerability map with 5 levels: Very Low, Low, Threshold Level, High Resilience and Very High Resilience. Based on vulnerability map, most of the Northern, Eastern and North Western parts of Z.R.B were among the most vulnerable parts. Vulnerability on the central parts of Z.R.B took two forms of ‘very low’ and ‘low’ which were because of most adaptive capacity.
