Sediment Cell Concept Flashcards
Most coastal sediment is brought to the shore by
rivers
Cliff erosion is also an important source of sediment at most coastlines
Where coastlines are retreating by a few metres a year there is a large input of sediment to the coastal zone
Wind can also transport sediment to the shore and this can lead to the build up of …………
sand dunes
In high latitude coastal areas glaciers break off into the sea and sediment that was trapped within the ice is deposited at the
coastal zone
Sediment Cells are an important way of understanding the coastal system
They can be considered a
closed system as most sediment movement is contained within the cell
There are 11 sediment cells around the UK coastline
Sediment cells can be divided into sub-cells where the
inputs (sources), stores (sinks), transfers, and outputs within the system can all be identified
The sediment budget is the
balance between the inputs and outputs of sediment in the system
Coastal systems should be in a state where the sediment budget is in a state of
dynamic equilibrium
However, human activity and natural changes like climate change can disturb the state of
dynamic equilibrium.
In the exam you may be asked about the role of sediment transport in a coastal landscape. To achieve full marks you need to ensure that you explain the formation of more than one landform because the question is asking about the entire landscape rather than a specific landform.
