Question 1

Why is the sea level rising?

Answer 1

As air temperatures rise (due to climate change) the water in the oceans is warmed and expands. This process is called thermal expansion.

Question 2

How bad will sea level get and how will it affect different places around the world

Answer 2

However, the annual rate of rise over the past 20 years has been 0.13 inches (3.2 millimeters) a year, roughly twice the average speed of the preceding 80 years.

Question 3

How will climate change affect erosion/deposition?

Answer 3

sea levels to rise yet further — they are currently rising around 3 mm per year — and an increase in the frequency and magnitude of storm events.

Question 4

How will climate change affect storm frequency, intensity, and storm surges?

Answer 4

Global warming has already doubled the risk of Hurricane Katrina-magnitude storm surges in the U.S., according to a new study published Monday.

Question 5

Hard Rock engineering

Answer 5

Groynes-Stops longshore drift moving sediment along the coast

Sea wall-Reflects wave energy out to sea.Recurved shape focuses energy out to sea rather than undercutting the cliff.

Question 6

Soft Rock engineering

Answer 6

Beach Replenishment-Adding sediment to a beach builds up the beach height. The beach absorbs wave energy and prevents waves breaking at the base of the cliff.

Slope stabilisation-Vegetation is planted by laying geo-meshes and planting grasses and shrubs
