Section C: Physical Landscapes - Coastal Landscapes
Overzicht
Stand on a cliff top and nothing appears to be happening. Waves arrive, waves go back, and the rock looks permanent. It is not. A wave breaking against a cliff can generate pressures of tens of tonnes per square metre, and it does so several thousand times a day, every day, for centuries. The coastline you are standing on is a snapshot of a process that has not stopped and will not.
This lesson gives you the machinery to read any coast in an exam photograph. You will learn what makes a wave constructive or destructive, the four families of process that shape a shoreline, and how rock type and geological structure decide which landform appears where. You will build headlands, bays, caves, arches, stacks, beaches, spits and bars from those processes rather than memorising them as pictures. Then you will weigh the engineering that people use to hold the line, and follow one enormous scheme in the region from the reasons it was built to the conflicts it caused.
Doelstellingen
- The Middle and Far East have a range of diverse landscapes.
- The coast is shaped by a number of physical processes.
- Distinctive coastal landforms are the result of rock type, structure and physical processes.
- Different management strategies can be used to protect coastlines from the effects of physical processes.
- An overview of the location of major upland/lowland areas and river systems.
- Wave types and characteristics. Coastal processes:
- weathering processes - mechanical, chemical
- mass movement - sliding, slumping and rock falls
- erosion - hydraulic power, abrasion and attrition
- transportation - longshore drift
- deposition - why sediment is deposited in coastal areas.
- How geological structure and rock type influence coastal forms.
- Characteristics and formation of landforms resulting from erosion - headlands and bays, cliffs and wave cut platforms, caves, arches and stacks. Characteristics and formation of landforms resulting from deposition - beaches, sand dunes, spits and bars. Examples should be used from the region and integrated into the teaching of the content. The costs and benefits of the following management strategies:
- hard engineering - sea walls, rock armour, gabions and groynes
- soft engineering - beach nourishment and re-profiling, dune regeneration, mangroves
- managed retreat - coastal realignment.
- An example of a coastal management scheme in the region to show:
- the reasons for management
- the management strategy/strategies
- the resulting effects and conflicts.
