Influence Of Lithology On Erosion Along The Dungeness Bluffs, Gabrielle Alampay, George Kaminsky, David Parks, Samuel Angel, Kathy Troost, Amanda Hacking

Salish Sea Ecosystem Conference

Erosion along the Dungeness Bluffs, located along the Strait of Juan de Fuca, poses a serious hazard to landowners living above. Concurrently, species such as forage fish depend on sediment input from bluff erosion to replenish the beaches in which they spawn. Between 2001 and 2012, the Dungeness bluffs eroded an average of 0.36 m/y, ranging from 0.0 to 1.88 m/y (Kaminsky et al., 2014; Parks, 2015). The steep bluffs in the area are ~30-80 m tall and are composed of glacial and interglacial sediment that vary in composition and strength. Failure styles range from steady erosion due to raveling, …
