Seawalls and revetments are often built to protect coasure communities from erosion and storm surpore, but they can have unintended consultaces. Seawalls can reflect wave energy, increating scour at their base and destabilizing adjacent unprovident shorelines.

Thee Role of Coastal Geography in Climate Change
Climate change is reshaping the relationship between coasual geography and natural disasters.

Climate change alse influences hurricane intensity. Warmer sea surface temperatures provide more energy for hurricane development, leading to a greater proportion of Category 4 and5 storms. The destructive potential of hurricanes, metriud by the Power Dissipation Ingelmen, has increateed in recent decades.
