Sediment sources Flashcards
Rivers
Account for majority of the sediment.
Sediment is deposited in estuaries
Cliff erosion
Areas with unconsolidated cliffs that are eroded easily.
More erosion in winter months due to more storms
Wind
Coastal energy source. Causes sand to be blown up/along the beach
Sediment transfer by winds occur where there are sand dunes which can provide sediment inputs
Longshore drift
Sediment is moved along the beach due to prevailing winds which alter the direction of the wave
This allows sediment to be transported from one section of the coastline to another
Sediment budgets
Use data of inputs, outputs and stores to assess the gains and losses of sediment in a sediment cell
What is the littoral zone?
Area of land between the cliffs or dunes on the coast beyond the influence of the waves
