Erosion and Sediment Control Work for the Momijidani River Park, Check dam and erosion control facility in Hatsukaichi, Japan.
The erosion and sediment control work at Momijidani River Park combines check dams with garden design to manage water movement and prevent soil loss along riverbanks. The structure uses natural landscape elements integrated into the park to reduce erosion effectively.
The project began in 1950 when engineers from Hiroshima introduced new methods to protect the landscape. This early work established the foundation for sustainable water management practices in the region.
The facility shows how traditional Japanese water management techniques merge with modern environmental care. Visitors can observe practical methods that protect both water flow and soil together.
The best time to visit is during rainy seasons when the water control system is most active and visible. The site is accessible on foot and the riverside path offers a good view of how the entire system functions.
The facility received the Handmade Hometown Prize in 1987 and again in 2005 for its environmental work. This double recognition shows how the project has maintained its value over decades.
