In 1980s, studies on the river environment and the management techniques to maintain the quality of water achieved actively. From the beginning of 1990s, the concept considering the river ecology and conservation in urban area have been introduced in Korea. Recently, some environment friendly projects on the rivers have been executed and some are under way. Many small rivers in rural areas have been maintained considering landscape and partly ecology. However until the pilot project named Songsam drainage channel project started in 1998, there were no studies and projects on the irrigation and drainage channels considering environment friendly maintenance. Korea Agricultural and Rural Infrastructure Corporation (KARICO) is going to introduce environment friendly and naturally favorable maintenance technique when the new projects to reform the irrigation and drainage channels are planned. Irrigation channel in O-dong project site in Yeomsan-myeon, Younggwang-gun was designed considering environment friendly consolidation and maintenance. |
