Q

Modify the event

A

Using engineering techniques to reduce the hazard intensity

21
Q

Mega-disaster

A

Large-scale disasters spatially, economically and socially which are difficult to manage and usually require international aid

22
Q

Development

A

The standard of living, wealth and quality of life common in an area

23
Q

Tectonic processes

A

Physical processes as a result of internal Earth structure and plate movement

24
Q

Geological structure

A

The layout of rock, including micro and macro-feature

25
Isostatic
The movement of the land (either subsidence or accretion) relative to the sea
26
Rocky coasts
An erosion dominant coast in a high energy environment, usually with resistant geology
27
Weathering
The breakdown of rock in situ (in its place)
28
Marine erosion
The removal of rock by wave action
29
Submergent coastlines
Coastal landscapes resulting from a positive change in relative seal level
30
Mass movement
The down slope movement of rock due to gravity
31
Coastal flooding
when the sea water temporarily inundates the land
32
Lithology
the properties of the strata of rock, such as resistance or permeability
33
Cost benefit analysis
the weighing up of financial loss scenarios, with social and environment impacts, to aid policy decision making
34
Littoral zone
A dynamic zone of change which includes the back shore, foreshore, nearshore and offshore
35
Shoreline management plan
A plan of ICZM strategies for an entire sediment cell where a cost benefit analysis has been done
36
coastal recession
The retreat of the coastline due to erosion and/ or sun aerial processes
37
Sustainable management
Managing the wider coastal zone designed to cope with future threats (increased storm events, rising sea levels) for an overall social, economic and environmental benefit
38
Coastal landscapes
The combination of different physical features at the coast, including rocky, sandy and estuarine
39
Environmental impact assessment
A report of the short and long term impacts of potential policy decisions on physical processes, fauna and flora
40
sediment cell concept
A system where sediment is sources transfers and sinks resulting in an dynamic equilibrium
41
Sea level change
The relative movement of the position of the sea compared to the land
42
emergent coastlines
Coastal landscapes resulting from a negative change in relative sea level
43
Discordant coastlines
Where strata are laid out at an angle to the coastline, creating features such as headlands and bays
44
Sub-aerial processes
Non-marine processes operating at the coast, including weathering and mass movement
45
Integrated Coastal Zone management
brings together groups and stakeholders with a range of different interests to share ideas and to establish sustainable levels of economic and social activity, while protecting the coastal environment
46
Coastal plain landscapes
found in areas of low relief with low energy and deposition dominant sandy or estuarine environments
47
Hard engineering processes
man made structures built to directly alter physical processes at the coast in order to protect it from erosion or flooding
48
Concordant coastlines
A coastline where strata is found in parallel bands
49
Eustatic
A change in the volume of water in the oceans
