Environment Agency provides maps of the coastal erosion management policy in England. The a-axis is the longest axis The b-axis is the widest axis at right angles to the a-axis. The distance between the crest and the trough. Beach material is higher on one side of the groyne. Wave cut platforms are only visible at low tide. Use your highlighter pen on each key word as they are really important for your exam.
Environment Agency provides maps of the coastal erosion management policy in England. What do you think are the most important reasons for protecting the coast at Tywyn? This section will help you to gather the primary data data you collect yourself and secondary data data collected by someone else that will support your analysis and conclusions. Select pebbles of different shapes and sizes from the beach. The mass of sediment in each sieve is measured using scales and the percentage of the total sample can be calculated.
Specialised geogra;hy Research question or sub question Causality How has the sea wall at x altered the rates of erosion and deposition? The low area in between two waves.
Coastal management – FSC Geography Fieldwork
Select pebbles of different shapes and sizes from the beach. 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.
Caves, Arches, Stacks and Stumps Caves, arches, stacks and stumps are usually found on headlands, where wave refraction is causing erosion on three sides. Split the line into segments where the slope angle changes.
How do these hard defences affect the beach sediment system? The sediment sample is placed in the top sieve then the sieves are shaken to sort the sediment into the various sieves.
Add an arrow to represent fetch too.
Sample a representative number of locations behind the coastal defences. Use statements with a balance of positive and negative. System How do groynes at x affect the sediment budget along the coast? Responses are limited to positions on a scale.
Beach profiles can also be used to calculate cross-sectional area and the amount of beach material present. The table below shows how the height of the defence can be categorised.

The cost of maintenance over a set time year period should be found in the same documentation and used for your calculation. How vulnerable is human activity to coastal flooding? Your task is to complete an RSA style video that incorporates the following: Here are a few suggestions: Use waterproof paint to mark each pebble. No ckursework Bermuda shorts though! What coastal management strategies are used? Environment Agency provides maps of the coastal erosion management policy in England.
Each sample should be placed in a sealed plastic bag and accurately labelled. Here are a few examples. The waves always look for weaknesses in the headland cracks and joints.
Geography Coursework- Coasts
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. The beach is the accumulation of sand between the lowest spring tides and the highest spring tides. Wave cut platforms are only visible corusework low tide. Coastal Protection Methods from guesta38fc Here are a few suggestions:.
Choosing a fieldwork location Choose a stretch of coast with some variation. Using the three images above and your own knowledge, explain why gcsf around the world are under threat. You can compare a series of groynes along a length of beach. Different sea defences require different levels of maintenance than others e. The distance between two crests or two troughs.
