This video (6:05) discusses characteristics of revetment and seawall design, how they may contribute to shaping the coast, and considerations for long-term effectiveness. Revetments and seawalls are types of coastal structures that run parallel along the shore. They are designed to stabilize and protect the coast against incoming wave action and erosion. While commonly implemented in the Great Lakes, revetments and seawalls interact with and alter natural processes, which may result in unintended physical, ecological, economic, and social impacts.
