  4. SHORELINE EROSION • Shoreline erosion depends on factors such as: • Rock type/hardness • Geometry of shoreline (e.g. lagoons are protected) • Wind direction, intensity, and currents • Vegetation cover Left: Green sand beach in Hawaii Right: South Point, just a couple km away • COASTAL STUDIES | 4 Department of Earth Sciences

  5. SHORELINE EROSION • Wave cut notches Sea arches and stacks Above: Wave cut notches in Hawaii. Top right: sea stack formation Lower right: Holei sea arch in Volcanoes National Park. http://www.flickr.com/photos/23679420@N00/5215649472/ • COASTAL STUDIES | 5 Department of Earth Sciences

  6. SHORELINE EROSION • Erosion creates loose sediment Above: Oblique wave action moves sediment along a shoreline. When the shoreline moves inland a sandbar known as a spit is formed. Curved spits are called hooks. • COASTAL STUDIES | 6 Department of Earth Sciences

  7. SHORELINE DANGERS • Hurricanes • Wind direction varies in different parts of the hurricane. • Storm surge more hazardous than high winds • Tsunamis • COASTAL STUDIES | 7 Department of Earth Sciences
