Kuchoro Sediment Retention Basin
Restoration Site 3 : Kuchoro Sediment Retention Basin
A sediment reduction measure has been implemented in another tributary.
Sediment control areas have been established on both banks of the Kuchoro River, a tributary of the Kushiro River. The site is located at the edge of the wetland and helps reduce sediment inflow into the wetland. 
The sediment control areas on both banks cover a total of about 60 hectares. Low walls were constructed to enclose the areas. During floods, water overflows the banks and is temporarily stored within these areas. The settling of suspended sediment in these areas helps reduce sediment inflow into the wetland. 
A large volume of sediment was effectively trapped at the site during the major flood in 2016.
