1.1: What is a coastal system and what are the dynamics of coastal environments?
The coastal system is one of inputs and outputs. There are 2 systems:
- The cliff system with inputs compromising the sub-aerial processes of weathering and the atmospheric processes of wind erosion; a throughput compromising cliff mass movement of falls, slips and slumps; and an output of sediment at the base of the cliff deposited or trasnported by marine processes.
- The beach system with an input of sediment from longshore drift (LSD), the cliff and offshore, a throughput of LSD and an output of LSD and destrive waves carrying sediment offshore.
- Areas of coasts usally…
