Dams are one of the first large man-made structures to control and dominate nature. The world’s first cities in the Middle East were built for permanent access to drinking and agricultural water along rivers, but since river flow in these areas was high in the months of the year and low and insufficient in the summer months, the dam was built from the beginning. Urbanization was considered.
One of the most important reasons for building dams from the beginning to before the invention of electricity is water storage, flood control and regulation and diversion of water, which is still one of the most important goals of dam construction in semi-arid regions of the world (such as the Middle East and North Africa).
The progress of the Islamic Revolution in the field of sound engineering
At present, Iran is the third top dam country in the world, which has the ability to implement large dam construction projects and export dam engineering services to other countries, including five African and Asian countries that are implementing large and complex dams, in its portfolio. At the same time, the knowledge and experience gained from the implementation process of the projects, achieving scientific standards, self-confidence and self-reliance of Iranian experts and adopting appropriate strategies, have not been ineffective in this regard.
Celebration of self-sufficiency in dam construction
Dr. Ahmadinejad, President of the Islamic Republic of Iran, after visiting the final stages of Karun 4 Reservoir Dam, fully operational the tallest concrete dam in the country.
The president will also address the celebration of self-sufficiency in the dam industry after the opening of the dam.
According to this report; Karun 4 Reservoir Dam is located in Chaharmahal and Bakhtiari province, about 180 km southwest of Shahrekord and 4 km downstream of the confluence of the Armand and Bazest rivers.
This project has been implemented with the goals of producing an average annual hydroelectric power of 2100 GWh, joining the Karun chain dams group in order to supply the water needed by industry and agriculture in the downstream plains and control the floods and destructive floods of the Karun River.
The dam-building movement is one of the achievements of 40 years of the revolution
Forty years after the Islamic Revolution, great achievements have been achieved, and the movement of dam construction and localization in the country is one of these very important achievements.
The CEO of Iran Water Resources Management Company spoke about the existence of 11 dams before the victory and establishment of the Islamic Revolution in the country and said: All these dams were built by foreign engineers and technicians, while after the victory of the Islamic Revolution a huge change occurred in the dam industry. Dad.
The CEO of Iran Water Resources Management Company stated: At present, there are 120 semi-finished dams under construction in Iran, of which 43 dams are for drinking purposes and should be put into operation by the end of the sixth plan, but should Announced that the implementation of these projects requires more than 15,000 billion tomans of capital. Also, in the plan to evaluate and review the dams, it was decided that these 43 dams will be implemented.
The dams of Iran
Also, among the dams under operation in Iran, Karun 3 Dam with a height of 230 meters can be mentioned as the tallest concrete dam in the country; Upper Gotvand Dam with a height of 182 meters from the foundation of the tallest earthen dam and Jagin Dam with a height of 80 meters from the foundation and a reservoir volume of 300 million cubic meters in normal figure, is the tallest roller concrete dam in the country.
The highest crown length is related to Chahanimeh 4 dam with a crown length of more than 15 km and a reservoir volume of 820 million cubic meters in the normal range on the border between Iran and Afghanistan and the highest reservoir volume is related to Karkheh dam with a reservoir volume of 5347 million cubic meters in the normal range. .
From the first of October 2005 to the end of September 2009, 18 dams were put into operation, but the peak of dam construction was in the tenth government with 39 dams. After that, the government of Tadbir and Omid was severely criticized in the discussion of dam construction, and this issue caused the number of dams operated in this government to decrease, and the 11th government, 25 dams and the twelfth government only three dams. To exploit. But in total during these years, 172 dams with a capacity of 51765 million cubic meters have been put into operation and according to the plans, now 672 dams are under operation, 120 dams are under construction and 176 dams are under study.
