Rick Besancon, P.E., an engineer with Burns & McDonnell discussed streambank stabilization. He gave a paper recently at the ASCE Environment & Water Resources conference on "green" bank stabilization. Stabilization is needed to protect property (including roads and bridges), prevents erosion and high sediment content in streams. The method he shared uses downed trees to stabilize the bank and allow resedimentation and stabilization. The photos below are before/in construction and after two years.
