Are coastlines managed successfully?

Purpose of this investigation
-is’ hold the line’ costal management successful at Swanage bay?
-is’ managed retreat’ successful at Studland bay?
Swanage bay
The coastal management at Swanage bay is hold the line they use both soft and hard engineering the soft engineering includes beach replenishment and cliff regarding the hard engineering includes groynes and seawalls.

My source is Google Earth we also looked at EdExcel Gcse B (Pearson) in class
On our trip to Dorset we are going to visit Studland and Swanage bay which are found on a discordant coastline they are both soft rock while in-between it is hard rock, they are both on the coast of the English channel Dorset is to the south of London
Studland bay

Studland bay
The coastal management at Studland bay is managed retreat Studland is a small village on the Isle of Purbeck in the English county of Dorset, they also planted marram grass so it can absorb the wave energy the marram is cheap and is soft engineering and is not expensive like hard engineering.
Dorset council have put up signs on the beach telling people not to step on and destroy the marram grass * This is how the area is managed vulnerable areas and areas recently planted with marram grass (which is used to stabilise the dunes) are fenced off to limit access and damage. * Boardwalks have been laid through the dunes to focus tourists onto specific paths. * Car parks have been provided and people are not permitted to drive onto the beach. * Fire beaters are positioned within the dune area in case of a fire. * Facilities including a shop, café, toilets and litter bins are provided near the car parks to focus tourists into one area. * Information boards educate visitors about the environment and how they can help to protect it.

Swanage bay
The coastal management at swanage bay is hold the line they use both soft and hard engineering the soft engineering includes beach replenishment and cliff regarding the hard engineering includes groynes and seawalls.

The picture below is Swanage it is located Swanage is located in Swanage Bay in Dorset on the south coast of England at The bay is east facing and is situated at the eastern end of the Isle of Purbeck, approximately 10 km south of Poole and 40 km east of Dorchester. The northern headland of the bay is formed of chalk, the southern of Purbeck Limestone, with softer primarily Wealden clays forming the bay and valley in which the town is sited.

Method of datacollection | Primary of secondary data | Method

Description of data collection technique | Explanation of why data collection technique was needed to show whether coastal management at swanage bay is a success | Risk involved | Explanation of how the risk was reduced | Groyne measurements by hand | Primary Data | At 5m from the sea we measured from the sand to the top of the groyne on the north and south side using a metre ruler | We needed this data to compare results between Google earth and our measurements by hand. Also to see whether the groynes have been trapping the sand and absorbing wave energy | It might not be that accurate compared to Google Earth’s measurements. | I reduced this risk by accurately from the sand to the groynes using a metre stick. | Bi Polar Survey | Primary Data | Ranking the appearance and effectiveness of the techniques used at Swanage and Studland. | We did this to see our ideas on how successful hold the line is at Swanage Bay. | No risks involved in a Bi-Polar Survey. | There are no risks involved in bi-polar survey | questionnaire | Primary data | Questioning people in the area questions based on Dorset. We did this by calling every 3rd person. | To see whether the public think ‘hold the line’ is successful at Swanage Bay. | It might have a biased view because everyone might have the same ideas. | To ask different people at different times. | Groyne Measurement Using Google Earth | Secondary Data | Using Google Earth we wrote down all the measurements from north and south side. | We did this to see whether the groynes are effective at stopping longshore drift and trapping the sand. | This will see the difference between using hand and Google Earth. | There was no risk involved in groyne measurement using Google earth | Orange Float | Primary Data | We stood 1metre from the sea and threw the orange into the sea. We measured in the direction the orange went and how long it took to reach 5metres. | To see which direction longshore drift and the strength of the wind as the shorter time the orange floats the stronger the wind. | Standing to close to the sea could result in the wind hitting you and pushing you away. | Move back so the wind doesn’t push you back. |
