Beaches Natural shore protection

Revetments Large, rough, angular rock (or rubble) on a slope 1.5 to 1 or less. Wave energy dissipates on the slope and on the rough surface. Some reflected wave energy, beach lakeward of stone is rare due to scour and changing water levels.

Seawalls Vertical structures at the water/land interface. Concrete block, cast-in-place concrete or steel sheet pile. High reflected wave energy, no beach. Easy access to the water.
