B. Techniques and References

Each stream bank erosion site has different considerations for choosing a treatment option including risk to property, stream form, function and flow and geophysical properties. Generally there are three different techniques:
Biotechnical - planting appropriate types of plants to stabilize the stream bank. Plants are utilized in a way that bring back vegetation to the area while providing stability to the slope. Some of the better plant species to be used are Purple Osier Willow and Red Osier Dogwood. These methods need time for plants to grow so a cover should be placed over bank to prevent further erosion. These methods include live fascinces, live stakes, and branch packing.
Hard armoring - placing barriers at the edge of the bank to reduce erosion. Hard armoring techniques can provide very good protection but can be expensive. These techniques may require some professional assistance however. These methods  include placing rock riprap along the streambank.
A combination of both practices - both rock riprap and planting specific vegetation will provide the best protection. Bank reshaping to a gentler slope may also be needed for desired results.
