How vulnerable is human activity to coastal flooding? 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. There are two ways of presenting statements:. Responses are limited to positions on a scale. 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: Beach profiles Coarse sediment analysis:
As the arch gets bigger the weight of the arch roof gets too great and it collapses, leaving a stack. The mass of sediment in each sieve is measured using scales and the percentage of the total sample can be calculated. What do you think of the beach protection at Beesands? Samples of fine sediments clay,silt and sand will need to be taken from the beach to the lab. The distance between two crests or two troughs.
Here are a few examples. Because the cliff is moving backwards a wave cut platform an expanse of bare rock is created.
What do you think are the most important reasons for protecting the coast at Tywyn? To find out how waves move material many KM along the coastline. The distance between the crest and the trough. Headland A piece of land that sticks out into the sea. Your efforts will be presented to the rest of the world on YouTube and a winner chosen. Here are some densities of rocks often used for rip-rap.
Watch the really excellent video to the right hand side. The c-axis is the shortest axis Measuring shape The simplest way to record pebble shape is to classify the stone as very angular, angular, sub-angular, sub-rounded, rounded or very rounded using a Power’s Scale of Roundness. The movement of water and load up the beach.
The berm is a ridge long thin hill that forms at the top of the beach.

Click the diagram to make it bigger. How vulnerable are different places along the coast at x to geographh flooding and rising sea-levels? The sediment sample is placed in the top sieve then the sieves are shaken to sort the sediment into the various sieves.
Choose a stretch of coast with some variation. Often it is a good idea to word cgse question so that people could respond with positive answers, negative answers or a mixture of the two.
What is the impact on the hard defences on longshore drift and the rate of deposition?
Choose a small number of categories for the types of land use. When did the sediment balance change from accretion to erosion?
Coastal management – FSC Geography Fieldwork
The slight acidity of sea water causing bits of the cliff to dissolve. In its simplest form likelihood can be scored depending on coqsts estimated height of the sea defence above a high tide or storm tide. How do these hard defences affect the beach sediment system? Overtime the crack may turn into a cave.
The simplest way to record pebble shape is to classify the stone as very angular, angular, sub-angular, sub-rounded, rounded or very rounded using a Power’s Scale of Roundness. Secondary data sources 1. Different sea defences require different levels of maintenance than others e. RSA videos are those that are manipulated by speeding up, slowing down, time lapse and over dubbed with your voice.
Fine sediment analysis Samples of fine sediments clay,silt and sand will need to be taken from the beach to the lab. The process then starts again, with the erosion of the sea making a new wave cut notch. Task 2 – Now watch the first 2. You might remember seeing some examples produced by Year 11 students at the International School of Toulouse and Priory School, Portsmouth to the right. Is coastal squeeze happening at x? Low value housing, small businesses small convenience stores, independent garages, storage facilities.
Should anything be done about erosion of the sand dunes?
Here is an example. Length of coastline shown is approx 3km.
