The Coastal System
- Open System
- Inputs are received across the
boundary of the system
- Outputs are transferred across
the boundary of the system
- Inputs are received across the
boundary of the system
- Inputs
- Energy
- Drives the system
- Provided by
- Waves
- Winds
- Tides
- Currents
- Waves
- Irregularly boosted
by tidal waves
- Spatial variations,
resulting from
- Strength in the
wind
- Strength in the
fetch
- Number of storms, and the
intensity of these storms
- Strength in the
wind
- Temporal variations,
come as a result of a
seasonal, or daily scale
- Drives the system
- Sediment
- Provided in the system
from the erosion of the
coastlines
- Most sediment comes from
outside the system
- Brought mainly from rivers
transporting ranges of
sediment from land to sea
- Weathering and
mass-movement from
cliff faces
- Brought mainly from rivers
transporting ranges of
sediment from land to sea
- Provided in the system
from the erosion of the
coastlines
- Changes in
sea levels
- Human activites
- Energy
- Outputs
- Coastal landforms, both
erosive and depositional
- Accumulations of sediment
above the tidal limit
- Loss of wave energy
- Coastal landforms, both
erosive and depositional
- Processes
- Erosion
- Constructive wave action
- Longshore drift
- Main agent that
relocates material
- Relocates material, from
erosional coastlines, to where
depositional landforms are
constructive
- Main agent that
relocates material
- The wind
- Wind can also carry
materials from the
shoreline inland
- Wind can also carry
materials from the
shoreline inland
- Erosion
