Incredible Construction Process of a Giant Dam – Cutting Through Towering Mountains Under the skilled hands of the local people, dams have been built, becoming major irrigation projects and contributing significantly to economic development. A dam is typically built across a river to create a reservoir in the valley behind it, storing the water that flows naturally into it. Before dam construction, it is necessary to divert the river to create a dry area for the construction site. In the case of small rivers, the water can be diverted through a tunnel or a canal built around the dam. Soft rock and earth were excavated to form the route, while harder rock had to be blasted with dynamite. In the case of large rivers, building a separate canal to divert the water is not feasible and is too expensive. Instead, a dry construction pit is created on one side of the river, leaving the other side open for the water to flow. The first part of the dam is built in this dry pit. Once completed, the other side of the river will form another dry area, and the rest of the dam will be built. Meanwhile, the river flows through the openings in the completed dam, and the reservoir can begin to fill behind it.
