Take a screen shot of part of the video, crop and annotate with key features. 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. Each reading is taken from from break of slope to break of slope. The area of land between high tide and low tide. This is when sea water and air get trapped in cracks.
Caves, Arches, Stacks and Stumps Caves, arches, stacks and stumps are usually found on headlands, where wave refraction is causing erosion on three sides. Groyne measurements Rip-rap volume and weight measurements. Samples of fine sediments clay,silt and sand will need to be taken from the beach to the lab. Shoreline management plans are an essential source to find our more about about erosion and other coastal processes in your chosen length of coastline. Beach profiles Beach profiles use distance and angle measurements to help you investigate the shape of the beach. Shoreline management plans Shoreline management plans are an essential source to find our more about about erosion and other coastal processes in your chosen length of coastline.
Watch the really excellent video to the right hand side. For a more representative cost benefit analysis, consideration of different house and business prices depending on the location along the coastline should be taken into account. Rocks been thrown into the cliffs by waves and breaking off bits of the cliff. High resolution maps are available that show individual buildings and height above sea level. Bays are usually more sheltered so there is less erosive power, coursewodk you often find beaches in bays.
Is coastal squeeze happening at x? To clarify what we learnt last lesson, watch from minutes on the coasts to ckursework right. Bi-polar analysis Questionnaires Cost-benefit analysis.
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. Here are a few suggestions: If you painted a pebble bright pink, left it and came back one week later, the sea would have moved it to a completely different part of the beach.
Coastal management – FSC Geography Fieldwork
What happens to the sediment which has been eroded from the sand dunes? The movement of water and load back down the beach. How do these hard defences affect the beach sediment system?
Coasts are shaped by the sea and the action of waves. There are two ways of presenting statements: The top of the wave. Rip-rap volume and weight measurements Rip-rap or rock armour is often used as a technique of coastal defence. Complete the activities as set out.
Geography Coursework- Coasts
Sometimes the sea may erode through to the top of the headland following a large crack. Use your tally chart to find the most common land courzework at each location.
The distance between two crests or two troughs. A possible fieldwork location: Land use type Tally Score High-status retail e.
coastz It is influenced by the wind, fetch and depth of water. What coastal management strategies are used? Watch the two YouTube videos beneath and then study the diagrams next coursewwork them. Using the three images above and your own knowledge, explain why coastlines around the world are under threat. Hydraulic pressure will be the main type of erosion. Here is an example. Measuring size The size and shape of coarse sediments can be measured on the beach.
What is the impact of coastal management on longshore drift and the rate of deposition? Specialised concept Research question or sub question Causality How has the sea wall at x altered the rates of erosion and deposition?
Why is there a high risk coasfs flooding at Happisburgh purple shading but little risk of flooding at Walcott? After 20 minutes find as many pebbles as you can, and measure how far each has moved from the start point. This may lead to areas of land being lost to the sea Hold the line Keep the coastline at its present position.
