evidence: The Wadi Halfa Salient, named after Wadi Halfa, a nearby Sudanese city 22 kilometers south of the border, is a salient of the international border between Egypt and the Sudan along the Nile River to the north. The area is currently controlled by Egypt. The area (along with the Halaib Triangle and Bir Tawil) is created by two different definitions of the Egypt–Sudan border: the "political boundary" set in 1899, and the "administrative boundary" set in 1902.[1] [...] The Wadi Halfa Salient is roughly 9 kilometres (5.6 mi) wide and stretches finger-shaped on both sides of the original course of the Nile 25 kilometres (16 mi) to the north into Egyptian territory, with a total area of 210 km2 (81 sq mi). Because of the construction of the Aswan Dam and the flooding of Lake Nasser most of the area was flooded, affecting most of the villages of the area and the ancient city of Faras. Some of the people were resettled to New Halfa in the Butana region.
