3.1.1 landscapes and features of the littoral zone
littoral zone
The coast as a system
As with any geographical system, the coast, as a system, has inputs, stores, transfers and outputs
The system constantly strives to be in a state of dynamic equilibrium
The coast can be viewed as both an open system and a closed system
It is an open system because it receives inputs from the lithosphere, atmosphere, hydrosphere, biosphere and cryosphere
However, during research and coastline management the coast can be seen as a closed system where a specific sediment cell is examined
here are examples of positive feedback at the coast
As waves erode the cliff, material is released
This material abrades the cliff which results in even more cliff erosion
There are also examples of negative feedback at the coast
As the shore is eroded, the material makes the wave-cut platform wider
This can absorb wave energy and reduce the impact at the base of the cliff
