WebThe slope of a coast is critical to determining how water-level changes will affect it. Steeply sloping coasts experience small shifts in their coastlines as the water level changes; however, because wave action along steep coasts is concentrated within a narrow zone, small water-level increases can result in significant erosion of bluffs or dunes. http://www.hurricanescience.org/society/impacts/stormsurge/
WebThe key factors which affect coastlines are: The rock type/geology (see map below). Hard rock types are less likely to erode. The fetch of the wave and the strength of the wind.
