- Sediment Cells
- large features like peninsulas act as naturally barriers to prevent the transfer of sediment (for example the Llyn peninsula
- Sediment cells are generally thought of as closed systems (no sediment is transferred from one cell to another)
- However its unlikely that sediment cells are fully closed due to variations in wind directions and tidal currents , its inevitable some sediment will go between cells
- A sediment cell is a stretch of coastline associated with the nearshore area where the movement of sediment is mostly self contained
- The Holderness Coast
- Has sources of sediment (inputs) like Flamborough head chalk headland and boulder clay cliffs . Material is moved via Longshore drift
- Has sink zones for depositional processes like offshore bars and spurn head (spit) also Humber estuary
- operates in dynamic equilibrium under natural conditions sometimes inputs and outputs can be disturbed.
