You can compare a series of groynes along a length of beach. How vulnerable are different places along the coast at x to coastal flooding and rising sea-levels? The cost of maintenance over a set time year period should be found in the same documentation and used for your calculation. This is when sea water and air get trapped in cracks. 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.
The main ways that the sea erodes the coast are: The process then starts again, with the erosion of the sea making a new wave cut notch. Click the diagram to make it bigger. Shoreline Management Plans and Environment Agency documentation can provide you with values for the cost of the different types of sea defence in your study area. Specialised concept Research question or sub question Causality How has the sea wall at x altered the rates of erosion and deposition?
Using a protractor or concentric circle card, measure the minimum radius of curvature.
After 20 minutes find as many pebbles as you can, and measure how far geogrqphy has moved from the start point. Here are a few examples. Rip-rap volume and weight measurements Rip-rap or rock armour is often used as a technique of coastal defence.
Choose a small number of categories for the types of land use. 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.
Transportation – LSD 3. Follow a straight transect line from the edge of the sea to the end of the active beach. A pilot survey will show whether the criteria you have chosen are appropriate. You can ask geographical questions about anywhere on the coast.
Why is there a high risk of flooding at Happisburgh purple shading but little risk of flooding at Walcott? Maps and aerial photographs Historical maps and photographs Wind and wave data. Use rules or calipers to measure the a, b and c axes of each pebble.
Secondary data sources 1. Land use type Tally Score High-status retail e. Beach profiles Coarse sediment analysis: Measure in at least three heights along the beach profile for each groyne.
Rip-rap or rock armour is often used as a technique of coastal defence. 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.
Geography- Whistable Coast Project – GCSE Geography – Marked by
Headland A piece of land that sticks out into the sea. Spread the pebbles out in the swash zone, and place a marker further up the beach to geograpyy the start point for the pebbles. The speed that a wave is traveling. Flood risk at a coastal location can be quantified by taking into account the likelihood of gegraphy occuring and the severity of a breach or overtopping of sea defences. As the process continues the cliff starts to move backwards retreat. News reports and recent research articles provide interesting themes around which you can ask geographical questions.
What type of erosion can you see evidence of? No dodgy Bermuda shorts though!
Annotate all the main features using the description above. Specialised concept Research question or sub question Causality How has the coastss wall at x altered the rates of erosion and deposition? What geogrphy management strategies are used? Risk mapping Flood risk at a coastal location can be quantified by taking into account the likelihood of flooding occuring and the severity foasts a breach or overtopping of sea defences.
Use a tape measure to find the height of beach material on either side of a groyne. How vulnerable is human activity to coastal flooding? Beach profiles Beach profiles use distance and angle measurements to help you investigate the shape of the beach. The main ways that the sea erodes the coast are: How successful are the coastal management strategies used at x?
