A coastal landscape is a section of coastline that has a range of coastal features; some erosional, some depositional. It is distinguishable from neighbouring coastal landscapes by prevailing characteristics that dominate the form of the coastline there.
A coastal landscape will be an interaction between:
- The nature and structure of the rock or materials constituting the coastline.
- The climate component determining the range and intensity of weathering processes.
- The marine processes operating to produce features of erosion and deposition.
- The input of energy and sediment into the coastal zone.
- The amount of time that has passed to develop or interrupt processes operating to produce features.
Different coastal landscapes may represent:
- A high energy coastal environment dominated by developing features of erosion
- A low energy coastal environment dominated by relatively stable features of deposition.
- A variable energy (dynamic) coastal environment dominated by transfers of sediment between phases of erosion and periods of deposition.
- A coastal environment with little long-term change and time for the full evolution of coastal landforms into a state of stable equilibrium.
- A metastable coastal environment where processes (and thus, features) change rapidly such as with tectonic uplift, leaving relict features apparent.
- A historic coastal environment with evidence of ancient processes, sea levels and features with more recent features superimposed as a result of different conditions operating at times up to the present.
