Rocks, sand and stones being thrown into each other by the sea current and waves. 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. This is when sea water and air get trapped in cracks. Use a tape measure to find the height of beach material on either side of a groyne. Task 2 – What is the difference between hard and soft engineering? Sometimes the sea may erode through to the top of the headland following a large crack. Are these hard defences sustainable?
Measure the angle of rest of the boulder – is the widest facing facing straight into the waves, or does it lie at an angle? Your task is to complete an RSA style video that incorporates the following: You can compare a series of groynes along a length of beach. The size and energy of a wave is influenced by: The waves always look for weaknesses in the headland cracks and joints.
Because the cliff is moving backwards a wave cut platform an expanse of bare rock is created. At high coxsts the power of the sea attacks and erodes the bottom of the cliff.
Evaluating the impact and severity of flooding behind coastal defences Severity of coastal flooding can be determined by considering the properties that would be affected by flooding, especially their economic value or worth if damaged. You geograpgy not have to take any sediments from the beach to the lab. Both images above credit to the most excellent internetgeography. What happens to the sediment which has been eroded from the sand dunes?
The energy of the wind causes water particles to rotate inside the swell and courseowrk moves the wave forward.

A pilot survey will show whether the criteria you have chosen are appropriate. Slowly the cave will get bigger and cut all the way through the headland, making an arch. How vulnerable are different places along the coast at x to coastal flooding and rising sea-levels? The sediment sample is placed in the top sieve then the sieves are shaken to sort the sediment into the various sieves.
cousrework Here are some examples. 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.
Choosing a fieldwork location Choose a stretch of coast with some variation. What do you think are the most important reasons for protecting the coast at Tywyn? Add a 30 second diagram to your book to help you to remember.
Length of coastline shown is approx 3km.

Here is an example. Make foursework under the following headings please: It is the process by which material moves along the beach everyday. An effective questionnaire contains a mixture of closed and open questions: It is the highest voasts of the beach and is basically sand accumulated on the strand line twigs, litter, seaweed, etc.
Bays are usually more sheltered so there is less erosive power, meaning you often find beaches in bays. Weathering in coastal areas a. But there have been critics, such as the local MP, who has called the project ” Disney for ducks “.
The number of waves per minute. You can compare a series of groynes along a length of beach. After 20 minutes find as many pebbles as you can, and measure how far each has moved from the start point. Each sample should be placed in a sealed plastic bag and accurately labelled. The movement of water and load back down the beach. Annotate all the main features using the geographt above. Click the diagram coursewoek make it bigger.
We are going to learn about these next.
But there have been hcse, such as the local MP, who has called the project ” Disney for ducks ” What could you investigate by fieldwork? You can record your thoughts on the worksheet beneath. Research questions Sub questions What is the impact of the coastal defences at x? What is the impact on the hard defences on longshore drift and the rate of deposition?
