GEOGRAPHY GCSE COURSEWORK COASTS

The sieves are arranged in decreasing mesh diameter with the largest at the top. 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. Choose a series of opposing positive and negative statements. Read more at the Institution of Civil Engineers website. Environment Agency provides maps of the coastal erosion management policy in England. As the wave cut notch gets bigger, the weight of rock above the notch gets greater.

As the process continues the cliff starts to move backwards retreat. How resilient is the coast at settlement x to changing weather patterns associated with climate change? Coastal Erosion types of erosion Coasts being at the boundary of the land and the sea are extremely vulnerable to erosion. Hydraulic pressure will be the main type of erosion. Beaches cane be divided into backshore, offshore and foreshore. Click the diagram to make it bigger. Here is an example.

This has happened as a result of a number of erosional processes.

How resilient is the coast at settlement x to changing weather patterns coursewori with climate change? It is influenced by the wind, fetch and depth of water. Make notes under the following headings please: Beach profiles Beach profiles use geogrqphy and angle measurements to help you investigate the shape of the beach.

No dodgy Bermuda shorts though! At each location, tally the number of different types of land use found. Type of data Primary data collection technique Secondary data collection source Beach morphology Beach profiles Coarse sediment analysis: Questionnaires can be a geohraphy technique where there are many passers-by.

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. Use a stone card to measure the minimum radius of curvature.

Beach profiles use distance and angle measurements to help you investigate the shape of the beach. Measure the angle of rest of the boulder – is the widest facing facing straight into the waves, or does it lie at geograpjy angle? To find out how waves move material many KM along the coastline.

Choosing a fieldwork location Choose a stretch of coast with some variation. Risk What factors put the coast at x at risk of coastal flooding?

The waves always look for weaknesses in the headland cracks and joints. Beach profiles can also be used to calculate cross-sectional area and the amount of beach material present. Here are a few examples.

What type of erosion can you see evidence of? Are these hard defences sustainable? Why is there a high risk of flooding at Happisburgh purple shading but little risk of flooding at Walcott? The low area in between two waves. Split the line into segments where the slope angle changes. Here is an example. Eventually the cliff can not support its own weight and it collapses.

The table below shows how the height of the defence can be categorised.

Use your highlighter pen on each key courwework as they are really important for your exam. Annotate all the main features using the description above.

Coastal Management – FSC Geography Fieldwork

Use rules or calipers to measure the a, b and c axes of each pebble. 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: It is the process by which material moves along the beach everyday.

Different sea defences require different levels of maintenance than others e. Overtime the crack may turn into a cave. Caves, Arches, Stacks and Stumps Caves, arches, stacks and stumps are usually found on headlands, where wave refraction is causing erosion on three sides. Severity of coastal flooding can be determined by coasfs the properties that would be affected by flooding, especially their economic value or worth if damaged.

This section will help you to gather the primary data data you collect yourself and secondary data data clursework by someone else that will support your analysis and conclusions.
