Beach Erosion. Beach erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).Storm waves carry the sand offshore, depositing and storing the sediment in large sandbars.each erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).
What landslides and debris flows are. Landslides occur when masses of rock, earth, or debris move down a slope. Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels. What causes landslides and debris flows. Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. Mudslides usually start on steep slopes and can be activated by natural disasters. Areas where wildfires or human modification of the land have destroyed vegetation on slopes are particularly vulnerable to landslides during and after heavy rains.
