Stream Bank Stabilization

Stream morphology teaches us that streams have a mind of their own. They can be altered and over the years can change again. Sinuous or meandering streams can suffer from severe bank erosion. When water hits a bank, it is directed 90 degrees away from it. Stabilizing a creek or stream can use hard engineering (stone) methods or green (vegetation) methods depending on site conditions and erosion severity.  Learn more about streambank stabilization in our Stream Management Guide.

Streambanks recently restored by pulling banks back, arming toe with riprap, and planting vegation
Streambank toe armed with riprap prevents undercutting
In some cases gabion baskets, woven mesh wire filled with stone, may be necessary to arm steep streambanks and protect them from erosion
