GCSE GEOGRAPHY COURSEWORK COASTS

There are two ways of presenting statements:. G11 Mock G12 Mock. The slight acidity of sea water causing bits of the cliff to dissolve. Should anything be done about erosion of the sand dunes? How it works 2.

Here are a few examples. Different sea defences require different levels of maintenance than others e. How successful are the coastal management strategies used at x? Rip-rap volume and weight measurements Rip-rap or rock armour is often used as a technique of coastal defence. 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. This is judged by eye.

The processes that take place are erosion, transportation and deposition.

Geography Coursework- Coasts

Bay An indented area of land normally found between two headlands. System How do groynes at x affect the sediment budget along the coast?

Fine sediment analysis Samples of fine sediments clay,silt and sand will need to be taken from the beach to the lab. Because the cliff is moving backwards a wave cut platform an expanse of bare rock 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.

The process then starts again, with the erosion of the sea making a new wave cut notch. Should anything be done about erosion of the sand dunes?

The sediment sample is placed in the top sieve then the sieves are shaken to sort the sediment into the various sieves. Headland A piece of land that sticks out into the sea. Use secondary data to find the rock type used and its density.

Slowly the cave will get bigger and cut all the way through the headland, making an arch. The sieves are arranged in gwography mesh diameter with the largest at the top. Risk and vulnerability 9. Eventually the cliff can not support its own weight and it collapses.

Responses are limited to positions on a scale. Please rank the following statements from 1 most important to 6 least courework Answers: If this happens a blowhole is created.

Coasts & Management – GEOGRAPHY FOR & BEYOND

Use a tape measure to find the height of beach material on either side of a groyne. Complete the activities as set out.

Take a screen shot of part of the video, crop and annotate with key features.

To clarify what we learnt last lesson, watch from minutes on the coasts to the right. Again, record your thoughts on the worksheet. Cost benefit analysis assessments of coastal defences take into account the cost of a defence and the value of the land and properties that it protects.

Annotate all the main features using the description above. Add an ggcse to represent fetch too. Overtime the crack may turn into a cave.

How do these hard defences affect the beach sediment system? Both images above credit to the most excellent gcae. What do you think are the most important reasons for protecting the coast at Tywyn?

Follow a straight transect line from the edge of the sea to the end of the active beach. Over time this erosion creates a wave cut notch basically an eroded hole coursfwork the bottom of the cliff.

Transportation – LSD 3. What type of erosion can you see evidence of? Low value housing, small businesses small convenience stores, independent garages, storage facilities. The simplest way to record pebble shape is to classify the stone as very angular, angular, sub-angular, sub-rounded, rounded or very rounded using a Power’s Scale of Roundness. Spread the pebbles out in the swash zone, and place a marker further up the beach to show the start point for the pebbles.
