‘1석3조’ 마을하천 보 철거 …“수질 개선·온실가스 감축·홍수 예방”
A recent study revealed that removing unnecessary dams and levees in small mountainous streams can lead to improved water flow, reduced greenhouse gas emissions, and flood prevention. In the case of Seongnam's Tancheon stream, removing 11 such structures could restore 30 million cubic meters of water annually and cut carbon dioxide emissions by 30 tons.
The Korea Forest Society recently published a report titled "Analysis of the Amount of Water Restoration, Flood Levels, and Impact on Water Quality and Flood Extent Due to the Removal of Unnecessary Dams in Small Streams," which analyzes the impact of dam removal on water restoration, flood management, water quality, and flood extent in seven small mountainous streams across the country.
The report emphasizes that removing unnecessary dams is part of a broader approach to water management, climate change mitigation, and flood risk management, rather than just an environmental restoration project.
