You can collect field data on the effectiveness of the rip-rap simply by measuring the length, width and height of each boulder. During the passage of a tropical storm, local weather stations will record an enormous increase in wind speed and rainfall. Therefore an appropriate sampling strategy is adopted to obtain a representative, and statistically valid sample of the whole. Further cliff retreat will form a wave-cut platform. Questionnaires can be a useful technique where there are many passers-by.
Constructive Waves – Scoil Mhuire Geography. It emerges at the base of the cliff 4. Method All Geography starts with someone going into the field to find out what’s there. Where the removal of beach material exceeds the supply erosion occurs. You Should have an easy to complete record sheet showing date, time and columns for each element of the weather you have instruments for. During the passage of a tropical storm, local weather stations will record an enormous increase in wind speed and rainfall.
What is coastal transportation?
Bi-polar analysis Construct your own environmental quality assessment. Scarborough 2 Coastal processes and erosion landforms.
High tides and storm waves will transport the cliff debris out to sea. A study of the range of different techniques used to manage the cliffs could highlight costs and benefits as well as potential impacts on physical processes and human activity.
Using a protractor or coursewirk circle card, measure the minimum radius of curvature. After 20 minutes find as many pebbles as you can, and measure how far each has moved from the start point. Observations and annotations should be made of:.
Small particles of sand swept out from the cliff by the spring water. Cliff retreat at Reculver 1. The cliff is undercut by the spring sapping which encourages cliff collapse and retreat. Use a tape measure to find the height of beach material on either side of a groyne.
This modal land use and its associated score can then be used in the flood risk calculation. High resolution maps are available that show individual buildings and height above sea level.
Care and accuracy important when measuring weather-instrument itself has to be suitable as well as its use accurate. Measure in at least three heights along the beach profile for each groyne. Maximum-minimum thermometer housed inside measures the highest and lowest temperature, often within a hour period.
The eastings or northings of the grid on a map can be used to identify transect lines C and D Alternatively, along a beach it could be decided that a transect up the beach will be conducted every 20 metres along the length of the beach.
This process occurs at the fieldwork site Reculver Destructive Waves The backwash of the wave, due to the way in which it breaks on the shore, is greater than the swash. Coasts menu Waves Wave Action. You can add this document to your study collection s Sign in Available only to authorized users. Find out about coastal erosion Find out about coastal depostion.
Use secondary data to find the rock type used and its density. This is judged by eye. Year 8 Coasts Revision PowerPoint This section will help you to gather the primary data data driff collect yourself and secondary data data collected by someone else that will support your analysis and conclusions.
For complaints, use another form. Over time this creates a net shift of material along the coast. Keith Barlett from the Royal Manor Arts College in Dorset has written an article introducing an investigation which uses this methodology.
Traction – large material is rolled along the sea floor. Cup Anemometer and wind valve: 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. Microclimate data can be collected in any location, coutsework the school grounds.
Therefore an appropriate sampling strategy is adopted to obtain a representative, coyrsework statistically valid sample of the whole.
Groyne measurements Use a tape measure to find the height of beach material on either side of a groyne. Beach profiles use distance and angle measurements to help you investigate the corusework of the beach.
