coastal processes

1. Introduction to Coastal Processes  Jessica O'Riley: Physical Geography

2. What are they? Coastal processes are natural forces that remove or deposit sediment from the coastline. The effects of coastal processes can be seen at every shoreline; however they differ largely due to which process have taken place. Weathering Erosion Transportation Deposition

3. Where are they?             All over the world!  Weathering and erosion can be seen at the Cliffs of Moher, Ireland.     Erosion and Transporation can bee seen at Dana Point CA Deposition is any sandy beach where sediment has been carried ThePhoto by PhotoAuthor is licensed under CCYYSA.

4. How does it affect us? Industries such as fishing and tourism affect the economy Florida's Red Tide cost the state 42 million dollars Climate change and rising sea levels create land loss

5. How doEs IT affect us cont.. The landloss in this area affects the survival many species  land loss includes native grasses, coral reefs, and wetlands that are critical for coastal  infastructure The loss of land greatly affects humans

6. WHy is it Problematic Out of all the processes costal erosion is the most problematic as it greatly impacts us.  Nantucket Island – sees up to 12 feet a year Weakens infastructure of larger  sea cliffs  Humans become much more vulnerable to extreme hazards, such as hurricanes 

7. Can anything be done Beach nourishment Vegetation planting Seaweed forests

8.          x Can anything be done cont. Seawalls  Revements Storm surge barrier – protects coastlines and reduces the effects from hurrianes and tsunamis

9. conclusion The effects of nature shape our coastlines Not all of them are good for life on earth Some processees give us a reason to celebrate summer  Others need beach nourishment construction Our coastlines must be protected
