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.
