Biotechnical Erosion Control is a method that uses both living and nonliving vegetation to help control erosion. An example of this is the cattails that were planted along the shoreline of Lock Erin. Rock Revetments are rock covers on slopes that protect it and its uplands from waves and currents that cause erosion. Bulkheads are walls that hold and prevent the sliding of soil. They are also used to provide protection from waves.
Groins are structures built perpendicular to the shore and extending out into the water.
They trap sand and slow its movement to protect the shore from erosion and enhance the beach. Infiltration and Drainage Controls are structures to control overland runoff, soil moisture, and ground water seepage to help improve bluff stability and prevent massive erosion. This includes horizontal drains, vertical walls, drainage trenches, and runoff diversions. Slope flattening is just what it sounds like. Large machinery is used to remove unwanted materials from one place and takes them to another.
