Consequences of climate change affect many aspects of human societies. Unfortunately, the impacts of climate change has less studied and analyzed In terms of security. One of the important effects of climate reimpacts is the impact on water resources of different regions. Access to proper water resources is one of the biggest challenges in the present century, as it is limited to water resources, and the consumption and demand of it is always increasing. Hence, the situation of water resources will play a significant role in the formation of relations flow and development movement in Iran's geographic space. Due to the growing importance of water competition, identification of the positive and negative capacities of the country's hydropolivalent can be used to provide the macro and micro strategies.
The present study is applied in terms of purpose. With descriptive approach following the systematic analysis of the spatial status of water resources (aqueous flows from neighboring countries and precipitation). It tries to analyze the challenges of dehydration and security consequences of water resources, especially in boundary and border areas.

Dehydration and water crisis in Iran are the result of physical and economic factors resulting from poor management of water resources. Other factors such as annual rainfall, persistent drought, limited water access, population increase, climate change, water distribution, different spatial dispersion, water efficiency in different sectors of agriculture and lack of sustainable water planning can not be ignored.
The above factors lead to a gradual reduction in agricultural activities, increasing tension and involvement over water resources, increasing unemployment and expanding poverty cycle, migrating to major cities and margins, emptying the land of the population, increasing trafficking, dissatisfaction,
