Long wavelength and low wave height. stronger swash than backwash. Low frequency and higher wave profile. Beach has low gradient profile.

When Acids in the sea water dissolves the rocks.
Corrosion solution
2 of 16
Projected public schemes evaluated in terms of social outcomes and profit/loss.
Cost-benefit analysis
3 of 16
geological period 65-135 million years ago
Cretaceous
4 of 16
Triangular accumulation of sediment such as sand and shingle.
Cuspate Foreland
5 of 16
movement of people to coastal areas. Can be negative in terms of intensive housing development along coastlines = enviornmental degradation.
Coastalisation
6 of 16
Coastal management where a situation is montiered whilst letting nature take its course. Only defence activity is safety measures.
Do nothing
7 of 16
When ecosystems become more fertile environments because of detergents, sewage and artificial fertilisers coming in.
eutrophication
8 of 16
Global change of sea levels possibly due to growth/decay of ice sheets.
Eustatic State
9 of 16
Balanced state of a system when inputs and outputs are equal. One element changes from outside influrence = balance is upset internally and components are altered. Feedback means system can adjust and regain the balance.
Dynamic Equilibrium
10 of 16
Identifies and protects both geological and biological interests.
National Nature Reserve (NNR)
11 of 16
the gradual evolution of a series of plants within an ecosystem or given area. This series of plant communities occurs in a roughly predictable order.
Plant succession
12 of 16
Dutch term for a flat piece of land that has been reclaimed from the sea, lakes or rivers by building dykes and draining. Polders are maintained by pumping.
Polder
13 of 16
the shape of the Earth’s surface. An area of ‘high relief’ has large differences in the height of the land; ‘low relief’ indicates little difference in altitude
Relief
14 of 16
A strategy to encourage the movement of the shoreline landward of its present position in a managed or controlled manner, hence the term ‘managed retreat’.
Retreat the line
15 of 16
the way in which the rock is constructed such as in layers or as a solid mass, its angle and direction and how it has folded or faulted
Rock structure
