Yalu River:
The Yalu River (Chinese) or the Amnok River (Korean) is a river on the border between China and North Korea. The Chinese name comes from a Manchu word meaning "the boundary between two fields". The Korean name is the Korean pronunciation of the same Chinese characters.
[edit] Geography
From 2,500 m above sea level on Baekdu Mountain, in the Changbai mountain range, on the China-North Korea border, the river flows south to Hyesan before sweeping 130 km northwest to Linjiang and then returning to a more southerly route for a further 300 km to empty into the Korea Bay between Dandong (China) and Sinŭiju (North Korea).
The bordering Chinese provinces are Jilin and Liaoning.
The river is 790 km (491 mi) long and receives the water from over 30,000 km² of land. The Yalu's most significant tributaries are the Changjin (장진강, 長津江), Heochun (허천강, 虚川江) and Tokro rivers. The river is not easily navigable for most of its length: although at its widest it is around 5 km, the depth is no greater than 3 m and much of the river is heavily silted.
[edit] History
The river basin is the site where the ancient Korean kingdom of Goguryeo rose to power. Many former fortresses are located along the river and the former capital of that Korean kingdom was situated at what is now the medium-sized city of Ji'an, China along the Yalu, a site rich in Goguryeo era relics.
Because of its strategic location between China and Korea, the river has been the site of several battles, including:
The Korean side of the river was heavily industrialized during the Japanese Colonial Period (1910–1945), and by 1945 almost 20% of Japan's total industrial output originated in Korea. During the Korean War the movement of UN troops approaching the river provoked massive Chinese intervention from around Dandong. In the course of the conflict every bridge across the river except one was destroyed. The one remaining bridge was the Sino-Korea Friendship Bridge connecting Sinuiju, North Korea to Dandong, China. During the war, the valley surrounding the western end of the river also became the focal point of a series of epic dogfights for air superiority over North Korea, earning the nickname "MiG Alley" in reference to the MiG-15 fighters flown by the combined North Korean, Chinese, and Soviet forces.
Since the early 1990s, the river has frequently been crossed by North Koreans fleeing to China contrary to government policy.
[edit] Economy
The river is important for hydroelectric power, and one of the largest hydroelectric dams in Asia is in Sup'ung Rodongjagu, 100 m high and over 850 m long, located upstream from Sinuiju, North Korea. In addition the river is used for transportation, particularly of lumber from its forested banks. The river provides fish for the local population.
