Coastal Systems and Landscapes
What is the coastline?
The coastline is a narrow zone where the land and sea overlap; it is the interface between land and sea.
It is where marie processes (processes of the sea), terrestrial processes (processes of the land) and atmospheric processes (of the air) interact to provide a variety of landforms.
Human activity/ intervention has an increased impact on coastlines.
Within the coastal topic we shall look at:
188.8.131.52- Coasts as natural systems
- systems concepts and their application to the development of coastal landscapes. ( how systems are related to the coastal system). This involves the inputs, outputs, energy, stores, components, flows/ tranfers, poitive /negative feedback, dynamic equilibrium.
- The concepts of landform and landscapes and how related landforms combine to create characteristic landscapes.
The coastline is a dynamic environment, this means that the coasline is constantly changing. The coastline is never static.
Coastlines go through changes...
Short Term Changes
- Through the effects of tides, a single storm surge or a management decision. Coasts may alter on a relativley quick time scale.
A storm surge is the rising of a large amount of water, usually due to a storm. Associated with low pressure weather systems.
Long Term Changes
- Processes related to changes in sea level - these happens over a much longer period of time.
Looking at the Coast through a sytems model approach.
Because of the earth complexity, geographers look at the world through a models approach to simplyfy it…
