Create a free website or blog at WordPress. This means that you normally end up taking more slope readings, but the profile that you draw is more accurate. View videos of coastal environments in the video gallery. Constructive Waves The much lower wave breaks on the shore and the swash carries material up the beach. Measure in at least three heights along the beach profile for each groyne.
Mappleton and the increased erosion to the south of the sea defences. There are three main processes at work in the sea. There are many different methods of sampling sediment. A through to H on the diagram For each change in slope, use the clinometer to take a bearing to record the slope angle ii. This means that you normally end up taking more slope readings, but the profile that you draw is more accurate. Beach profiles use distance and angle measurements to help you investigate the shape of the beach.
You do not have to take any sediments from the beach to the lab. You can add this document to your saved list Sign in Available only to authorized users. As the result longshore drift transports material from the beach to the south of the groyne and is not replenished.
After 20 minutes, you may find that some of the pebbles will have disappeared from the beach or moved in a different direction to the others. What is longshore drift?
Method All Geography starts with someone going into the field to find out what’s there. View images of coastal environments in the coastal galler y. Beach profiles Aims To survey courssework 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 courseaork finish at A and H on the diagram.
Once reading is noted, the water has to be tipped away daily. Longshore drift is a process responsible for moving significant amounts of sediment along the coast.
Care and accuracy important when measuring weather-instrument itself has to be suitable as well as its use accurate. The sediment sample is placed in the top sieve then the sieves are shaken to sort the sediment into the various sieves.
View the coasts menu. Interview surveys can be more detailed and more flexible than questionnaires, with open ended rather than closed questions and the opportunity for respondents to give their opinions without being pigeon-holed by option boxes. How might their removal affect the ecosystem Investigating water quality at the local beach — does it deserve its blue flag?
Each time the anemometer makes a full rotation, the wind speed is measured by the number of revolutions per minute RPM. Quadrats can be used to select sediment for sampling. Severity of coastal flooding can xoursework determined by courseworkk the properties that would be affected by flooding, especially their economic value or worth if damaged.
You can add this document to your study collection s Sign in Available only to authorized users. This process is repeated continuously. Cup Anemometer and wind valve: This means that you normally end up taking more slope readings, but the profile that you draw is more accurate.
There are 3 to 4 cups mounted on a vertical pole. Measure in at least three heights along the beach profile for each groyne. You can collect field data on the effectiveness of the rip-rap simply by measuring the length, width and height of each boulder.
The population can be divided into known groups, and each group sampled using a systematic approach.
You can compare a series of groynes along a length of beach. SEA Spring sapping at Reculver 1. For example, the prevailing wind along the Holderness Coast is north-easterly.

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. Constructive Waves – Scoil Mhuire Geography. Many ranging poles have stripes which can be used for this purpose. Landforms of erosion Find out about erosional landforms. Measure the angle of rest of the boulder – is the widest facing facing straight into the waves, or does it lie at an angle?
Drainage Basin Hydrological System. At the southern-most edge of the Holderness Coast material is then deposited forming Spurn Point, a coastal spit.
