Role Of The Inputs In Coastal Systems Flashcards
What is an open system?
A system where both energy and matters are able to enter and leave the system
What type of system is the coast?
The coast in an open system, however, sediments cells can be a closed system
Matter transported into the coast system are
Sand and sediment
Matter transferred out of a coast is
Sediment removed beyond local sediment cells
Components/stores in a coast?
Landforms of erosion and landforms of deposition
Flows/transfers in a coastal system?
Wind and water transport
Negative feedback example in the coast?
A beach dynamic equilibrium > sediment is eroded from the beach during a storm > sediment is deposited offshore form home an offshore bar> waves now forced to break before reaching the beach dissipating their energy and reducing further erosion when they reach the beach > when the storm calms, normal wave conditions rework sediments from the offshore bar back to the beach > a beach in dynamic equilibrium
