Coastal Flooding

What is Eustatic Sea Level Change

Global change - ice melting / thermosteric sea level rise

What is Isostatic Sea Level Change

Local change - vertical movements of land (mass movement)

What are the 4 causes of Coastal Flooding

Sea level rise / Storm Surges / Tsunami's / Coastal Erosion

Describe Storm Surges

Strong winds push seawater towards the shore, raising sea levels above normal. This excess water overwhelms coastal defences and floods low-lying land, especially at high tide

Describe Tsunami's

Generated by an earthquake, where a tectonic plate moves, it leads to displacement of water, which travels at high speeds as energy to a destination.

Describe Coastal Erosion

This causes for the removal of natural barriers, so therefore less protection of the coast, and more vulnerability to flooding"
