Upper Atbara and Setit Dam Complex for local agriculture, supplying potable water, and power generation. The project also aimed to increase agriculture production in the New Halfa area of Kassala currently irrigated by the Khashm el-Girba Dam, and the development of new land consisting of in Upper Atbara. Additionally, the dams are expected to provide flood-protection measures along the river banks by regulating the river flow in the project area. The total cost of the dam complex is estimated at $1.9 billion, of which $838 million for the construction of the dams is from the China Three Gorges Corporation (CTG) and its overseas project-contracting subsidiary, China
Three Gorges Dam spillway gates of the dam might pose a risk of cavitation, similar to that which severely damaged the poorly designed and cavitating spillways of the Glen Canyon Dam in the US state of Arizona, which was unable to properly withstand the Colorado river floods of 1983. However, 163,000 concrete units of the Three Gorges dam all passed quality testing and the deformation was within design limits. An experts group gave the project overall a good quality rating. In order to maximize the utility of the Three Gorges Dam and cut down on sedimentation from the Jinsha River, the upper course
