The construction of dams is determined by the flow of the river and the position of the surrounding area; most of the tallest dams are placed between valleys and hills, which makes the dam easier and stronger to build. Nurek Dam, located in Tajikistan, is now the highest in the world, standing at 300 meters. There are numerous tallest dams under construction, including 335m in Tajikistan and 312m Shungjiangkou Dam in China, which, when finished, might rank first and second on the list. When compared to other nations, China has several of the largest and tallest dams, and many of the tallest dams are currently under construction. After construction, China will have four dams in the top ten lists of the world’s highest dams.
