LONGSHORE DRIFT COURSEWORK

Choose a small number of categories for the types of land use. What landforms are created by coastal erosion? Beach profiles use distance and angle measurements to help you investigate the shape of the beach. Upload document Create flashcards. 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.

Please rank the following statements from 1 most important to 6 least important Answers: What do you think of the beach protection at Beesands? Measure in at least three heights along the beach profile for each groyne. The lists below give you an idea of some of the ways that data collected within a microclimate investigation can be used. The swash moves beach material along the beach and the backwash, under gravity, pulls the material back down the beach at right angles to the coastline. Please rank the following statements from 1 most important to 6 least important. Type of data Primary data collection technique Secondary data collection source Beach morphology Beach profiles Coarse sediment analysis:

Cup Coursewwork and wind valve: 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.

Readings should be taken preferably at same time each day. Use waterproof paint to mark each pebble.

This usually occurs in one direction as dictated by the prevailing wind. View images of coastal environments in the coastal galler y. Coasts — The essentials. Keith Barlett from the Royal Manor Arts College in Dorset has written an article introducing an investigation which uses this methodology. You can compare a series of groynes along a length of beach.

Beach profiles Aims To survey the shape morphology of a beach To compare beaches or coastlines in different locations To examine the effects of management on beach processes and morphology To investigate seasonal changes in the beach profile To examine relationships between the beach profile and other factors, for example rock type, cliff profile, sediment size or shape Equipment Tape measure Ranging poles Clinometer or pantometer Compass Recording sheet Methodology Select sampling points for beach profiles across the width of the beach At each sample point in turn, place a ranging pole at the start and finish at A and H on the diagram.

What lives on or around them? Although longshore drift is the main process of transportation the material moves in four different ways. Method All Longdhore starts with someone going into the field to find out what’s there.

Beach profiles can also be used to calculate cross-sectional area and the amount of beach material present. This process is repeated continuously. For example, from point A to point B in the diagram below.

Longshore Drift – A Level Geography

These sub-sets make up different proportions of the total, and therefore sampling should be stratified to ensure that results are proportional drjft representative of the whole. How often do you go to the supermarket? The number of revolutions is recorded over time and an average is determined.

Flood risk at a coastal location can be quantified by taking into account the likelihood of flooding occuring and the severity of a breach or longshord of sea defences.

Rain is collected in a measuring flask and the measurement can be read easily. Add this document to collection s.

Cost benefit analysis assessments of coastal defences take into account the cost of coureework defence and the value of the land and properties that it protects.

This makes the readings fair. Groyne measurements Use a tape measure to find the height of beach material on either side of a groyne. Wind valve measures wind direction.

Investigating the value which people place on a local beach Investigating a litter problem or another issue: Bi-polar analysis Questionnaires Cost-benefit analysis.

Follow a straight transect line from the edge of the sea to the end of the active beach. Use a stone card to measure the minimum radius of curvature. Cost-benefit coureework Cost benefit analysis assessments of coastal defences take into account the cost of a defence and the value of courwework land and properties that it protects.

Many ranging poles have coyrsework which can be used for this purpose. Beach profiles Coarse sediment analysis: This site uses cookies. Each sample should be placed in a sealed plastic bag and accurately labelled.

As the result longshore drift transports material from the beach to the south of the groyne and is not replenished.
