  • Abstract
Before 1960s, most streams and rivers in Korea were in natural conditions with few artificial structures such as dams and levees. In this period, the natural functions of the streams such as ecological habitats were well preserved. Since 1960s, streams and rivers in Korea have been ‘socially’ evolved in four or five distinct stages with urbanization and industrialization progressed. Each stage is called Natural Stream, Disaster‐Prevention Stream, Occupied Stream, Park Stream, Close‐to‐Nature Stream. Since the early 1990s, degradation of the natural ecosystem became one of the most important social issues, with the environmental pollution of the land and streams caused by the growth‐oriented development policy. Urban stream restoration in Korea started in the early 1990s. The first stream restoration project, a test project for research‐purpose, was initiated in the mid 1990s by a public sector. For a test stream where various techniques proposed in the research were to be applied, they selected the Yangaje‐cheon (stream), a small urban stream in southwest Seoul. Since the research project was proven successful, several demonstration stream restoration projects have started from the late 1990s such as the Gyeongan River Project, mostly by the river managers in the central government. Numerous small restoration projects are presently being implemented, although they focus mainly on the improvement of stream water quality and enhancement of the riparian aesthetic value rather on restoring the ecosystem of the river.
