Coastal erosion involves the breaking down and removal of material along a coastline by the movement of wind & water it leads to the formation of many landforms and, combined with deposition, plays an important role in shaping the coastline. 103 chapter 4 protection from coastal erosion thematic paper: the role of coastal forests and trees in protecting against coastal erosion gegar prasetya1 1 introduction. Coastal hazards refer to the risks of life and property on the coastline that are created by coastal flooding, high winds and waves, short- and long-term shoreline erosion, and storm surges the risk that a natural hazard poses is considered by estimating the impact that it would have on the people, services, facilities, and structures in a .

Coastal processes coastal landforms are created by a wide variety of coastal processes, which vary depending on the and coastal flora organisms cause erosion by . One cause of ongoing natural coastal erosion is a longshore increase of sand transport: in this case more sand is leaving a coastal section than entering as longshore sand transport (also called littoral drift) depends primarily on the direction and height of breaking waves, a gradient in longshore transport can be due to longshore varying wave conditions, coastline curvature, or nearshore .
