Then, watch from 10 minutes onwards. They are attacked by the immense power of the sea and the weather. Use a tape measure to find the height of beach material on either side of a groyne. The stack is then eroded by the sea and weathered from the air leaving a stump. Often it is a good idea to word the question so that people could respond with positive answers, negative answers or a mixture of the two.
Rip-rap volume and weight measurements Rip-rap or rock armour is often used as a technique of coastal defence. Beach profiles Coarse sediment analysis: Over time this erosion creates a wave cut notch basically an eroded hole at the bottom of the cliff. Beach profiles use distance and angle measurements to help you investigate the shape of the beach. The a-axis is the longest axis The b-axis is the widest axis at right angles to the a-axis. The table below shows how the height of the defence can be categorised. Bi-polar analysis Questionnaires Cost-benefit analysis.
No dodgy Bermuda shorts though!
We are going to learn about these next. Research questions Sub questions What is the impact of the coastal defences at x? The c-axis is the shortest axis Measuring shape The simplest way to record pebble shape is to classify the stone casts very angular, angular, sub-angular, sub-rounded, rounded or very rounded using a Power’s Scale of Roundness.
Wave Cut Notch and Wave Cut Platform Wave cut platforms are made in a similar ways to waterfalls and gorges rivers topic. Rip-rap or rock armour is often used as a technique of coastal defence.
Geography Coursework- Coasts
You can compare a series of groynes along a length of beach. How successful are the coastal management strategies used at x? The sieves are arranged in decreasing mesh diameter with the largest at the top.
Choose a series of opposing positive and negative statements. Use geograpny paint to mark each pebble. Often it is a good idea to word the question so that people could respond with positive answers, negative answers or a mixture of the two. Watch the cliff collapse video in Cornwall, UK, to the right.
This section ckursework help you to gather the primary data data you collect yourself and secondary data data collected by someone else that will support your analysis and conclusions.
Task 2 – Now watch the first 2.
Waves refract around headlands so they experience a lot of erosion forming features like arches and stacks see below. Here are a few suggestions: To discover how erosion causes different coastal features. Click the diagram to make it bigger. What’s in your backyard? Low value housing, small businesses small convenience stores, independent garages, storage facilities. As the arch gets bigger the weight of the arch roof gets too great and it collapses, leaving a stack. Beach profiles gcwe also be used to calculate cross-sectional area and the amount of beach material present.
This has happened as a result of a number of erosional processes. Transportation geograaphy LSD 3.

The stack is then eroded by the sea and weathered from the air leaving a stump. Do nothing Allow natural processes to take over. Cokrsework are formed when you get alternate layers of hard and soft coastts. As the wave cut notch gets bigger, the weight of rock above the notch gets greater. Land use type can be recorded as a tally as shown above, values for different types of land use can also be found in secondary sources.
Rocks, sand and stones being thrown into each other by the sea current and waves.
The number of waves per minute. Beach profiles use distance and angle measurements to help you investigate the shape of the beach.
Coastal Management – FSC Geography Fieldwork
Here are a few suggestions:. If this happens a blowhole is created. Risk mapping Flood risk at a coastal location can be quantified by taking into account the likelihood of flooding occuring and the severity of a breach or overtopping of sea defences.
