Security complex represents a unique group of countries where the process of "security building" and "making insecure" or both for this group of countries are increasingly related with each other. In other words, their main security concern is so intertwined that their security problems cannot be solved independently. Thus conceived, "hydropolitic complexes" include those countries which are geographically the owner and from technical point of view, are the user of part of the shared river. In fact, a group of the countries which are considered to be part of a region due to their water resources (rivers, lakes and aquifers), would have no common geographical borders but their "national security" and "hydropolitic security" are so interrelated that their security and hydropolitc problems cannot be resolved without their cooperation. The methodology of current descriptive-analytic study focused on Mesopotamia and Hirmand drainage basins (in parts of Iran), is grounded on the hypothesis that in a hydropolitic complex in the same way that the threatening of water security of each one of the member states might lead to the threatening of national security of other members, some threats can be posed against the water security of each one of the member states due to the threatening of the national security of other members. The data required for this research have been collected using library sources (books, journals and internet). The results of this study showed that how hydropolitic security is endangered following the eruption of insecurity in Afghanistan. At Tigris and Euphrates Basin, the climate changes and Turkey's inattention to hydropolitic security of Syria (by closing the floodgates of the dams) provided the ground for the emergence of internal crisis in Syria, and its reverberations posed serious threats against the security of Turkey, Iraq and Iran.
