Abstract

The Anyang River which located in an urban area near Seoul had been managed focusing on supplying home and industrial water and preventing floods, coping with rapid industrialization and urbanization. Consequently, it was changed into a deadly river during 25 years. Its channel was straightened by concrete and water quality deteriorated to BOD 190mg/l. In addition, water quantity has been rapidly decreased and has been drying up. Also, as the river ecosystem, landscape, water-friendly function, and so forth were seriously deteriorated, people turn away from the urban river. From 2001, the master plan under the 10-year has been actively carried out centering on the preceding items, which are healthy river in which fishes inhabit, safe river free from floods and droughts, and pleasant river where citizens visit. As a result, its water quality was remarkably improved by BOD 5mg/l in 2005 and some upper zones were improved enough to allow people to swim. Moreover, various animals including fish and birds gather around the river. Now, the 'Anyang River Restoration Project' is recognized as the first comprehensive and systematic nature-friendly urban river improvement in Korea.
