This has happened as a result of a number of erosional processes. Is there any historical evidence for changing land use along the coast at x? If this happens a blowhole is created. Rocks, sand and stones being thrown into each other by the sea current and waves. What historical evidence is there for the impact of these hard defences? Explore real-time data including wave direction and height and a gallery of photographs from across the coast of England and Wales at the Channel Coast Observatory http: Specialised concept Research question or sub question Causality How has the sea wall at x altered the rates of erosion and deposition?
Here are a few suggestions:. Bi-polar analysis Questionnaires Cost-benefit analysis. The slight acidity of sea water causing bits of the cliff to dissolve. How it works 2. The movement of water and load up the beach.
The main ways that the sea erodes the coast are: Flood risk at a courseqork 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.
Annotate it with as much detail as possible. The table below shows how the height of the defence can be categorised. Risk and coaxts 9.
Bays are usually more sheltered so there is less erosive power, meaning you often find beaches in bays. Watch the cliff collapse video in Cornwall, UK, to corusework right. Explore real-time data including wave direction and height and a gallery of photographs from across the coast courdework England and Wales at the Channel Coast Observatory http: Choose a small number of categories for the types of land use.
Split the line into segments where the slope angle changes.
Erosion of headlands joint, crack, cave, arch, stack, stump 2. Transportation foursework LSD 3. If you star in the photo, you will gain extra credit. Sample a representative number of locations behind the coastal defences. Fine sediment analysis Samples of fine sediments clay,silt and sand will need to be taken from the beach to the lab. Use waterproof paint to mark each pebble.
Weathering in coastal areas a. We are going to learn about these next. Using a protractor or concentric circle card, measure the minimum radius of curvature.
If this happens a blowhole is created. Bi-polar analysis Questionnaires Cost-benefit analysis.
The berm is a ridge long thin hill that forms at the top of the beach. You can ask geographical questions about anywhere on the coast. The sieves are arranged in decreasing mesh diameter with the largest at the top. High resolution maps are available that show individual buildings and height above sea level.
Should anything be done about erosion of the sand dunes? Task 5 – Either using the photo of the beach in Conwy, North Wales or your own beach photo, annotate the key features of the beach and how it formed.
Each research question has been split into 2 or 3 sub-questions. Secondary data sources 1. Type of data Primary data collection technique Secondary data collection source Beach morphology Beach profiles Coarse sediment analysis: To show the spatial change of land use along your stretch of coastline, the buildings can be marked on a map using colours or symbols for different types of land use. Rocks been thrown into the cliffs by waves and breaking off bits of the cliff.
Read more at the Institution of Civil Engineers website. Distance away from the sea defence and height above it should also be taken in to account when surveying land use. News reports and recent research articles provide interesting themes around which you can ask geographical questions.
