Q

what does
qualititive and quanitiave mean .

A

qualititive - descriptions , photos .
quantiitave - numbers and data .

20
Q

FIELD WORK TECHNIQUE 1 - BIOPLAR SURVERY OF THE COASTAL DEFECNES

-both qualitative +quantittave data

A

We dd 5 bi-polar surverys of different coasal defecnes , in three sites of th coast e.g roc rmour .

-We had eight different factors , e.g if it was vulnerble to eorios , if it was good flood defecne .
-it rnaged from -2 to +2 -2 being owrst +2 being the best ,
-Tthis was rated based on our opinion .

21
Q

Justification of Bi-Polar Method .

A

I would be able to judge which defence is most effective bya ddin upt he totl of each defence strategy The one witht he highest score , would be the most efective coastal defence .

22
Q

FIELD WORK TECHNIQUE 2 -HEIGHT OF THE BEACH EITHER SIDE OF THE GROYNE .
-Quantitive

A

-We used a metre ruler tomeasure , the hieght of the groyne on the East , West ,at 3 points along the groyne .
-Near the sea , in the middle , and at the back of the beach .

23
Q

Justification of groyne height ?

A

I would be able tojudge if the groynes were effective , by comparing the depths on the East and Wes side .
-The bigger the difference , the more effective the groynes s it means longshore drift has stopped .

24
Q

FIELD WORK TECHNIQUE 3 - FIELD SKETCH
Qualitiave

A

-Draw a view of the site , inclduing informtion about land duse , coasal defen es , geenrl information and apperance of the coast .

25
Q

Justification of field sketch ?

A

The more postiive the annotations = the mroe effective the management .

26
Q

What secondary sources (DATA COLLETION) COULD I INVESTIGTE

A

-Old maps .co.uk
-Swale council website swale.gov.uk
-Sheerness Times guardian (local newspaper,)

27
Q

Descritpion of the bipolar surveyys .

A

I drew a bi-polar line graph to present the daa , The lines were colourcoded based on each defence axic .
-I drew al tive defecnes on the graph .
-The x axis ges from +2 (posiite) to -52 , (negative ), The y -axid had categories .

28
Q

Justification of bipolar surveyp method .

A

-I wanted to draw all the lines onto oene grpah , which is colour coded ,s o i can compare gthe results , to see whcih one had the most postiieve points , and which one had the most negative points

-Moreover , it is more ismple to add the scores togehter and plce hte defences in order of effectiveness .
-Our opinion is established clearly in colours - negatives and positives .

29
Q

Description of Groyne height on either side of it .

A

-I drew three inverted bar charts for each location along the groyne (near the sea) .
-On the left , I drew a bar to represent the pebbles on the west side of the groyne .
-On the righ I drew a abr to represent the pebbles on the est side of the othe groyne .
-The scale of my y-zaxis went from (0-50).

30
Q

Justification of groyne height

A

-Drawing a bar graph for each loaction allows us to make clear comprisions .
-Therefore , evalate , the effectiveness of the groynes .
-Larger height differences between the est and wrst , means that the groyenes are more effective as it shows long hore drift has ben stopped .

31
Q

Description of field sketch ./

A

-Draw a neat version with clear developped annotoatoin .
-I made sure to add the coastal defecnes in my sketch , and my annotatons expalined the effectiveness of the coastal defences based on my opinion .
-I also noted down land use and erosion .

32
Q

Justification of field sketch .

A

-By drawing a neat version of the annotated ieldskeetch , we could see a clear and accuate representation of human built surroudins .
-Adnd whteher the coastal defecnes culd stop erosion/long shore drift .
-We were bael to see t he relationship between defences and land use .

33
Q

Key results of bipolar analysis .

A

-The average of all fivde defences was -0.6.
-Sugegesting that the coasta defences were not very effective .
-My best coastal defence score was the regraded slope (+4)
and my worst coastal score was no active inervention (-3_)

34
Q

explanation of results in bipolar analysis .

A

-Regraded slope ws the most effective agaisnt eriosn for me as it has low disruption to loacal people durng consturction .
-Management retreat was the worst for me , it was vulenable to eriosn , ugly ,a nd had a high safety risk .

35
Q

Results of height of the breach either side of the groyne .

A

-Overall the groynes were effective ..
-There was a lower average ont he East side 20 ,than on the west side 25 .

36
Q

explantion ofheight of the beach either side of groyne results .

A

-Near the sea , the groynes were ont very effective . because theyw ere submeged in sediment ,meaning longshore drift was not stopped .
-hwoever , enar the land and the middle , the beach was higher on the east , suggesting LSD , is being trapped by the groynes showining it is effective .

37
Q

Results of annotated field sketch .

A

-I drew detailed sketches of the three sited , to depict the levels of eriosion .
-By cmparing the defences with anonotations , I can comapre them to lanuse .
-From the sketches , I can conclude that (NAI) , was the least effective as I can see a lot of slumping from my sketch .
-Site 2 was the msot effective as I can see on mys ktch , there was multipe defences -e.g - groynes preventing long shore dift ,a dn RETAINING SEA WALL , preventing mass movememnt .

38
Q

EXPLANANTION , of my results .

A

-It has become evident , that area with MORE expensive and MUTLIPLE ,d efecnes e,g site 2
-Showed lower levels of erosion , I cans ee this htrough the elevels of sediment on either side of the goryne l, showing lsd being trapped .
-wehres NAI , ther wasn;t expensive defecnes , so mroe vulnerbale to eriosn . I sketched murk watch in mys ketch suggesitng sediment washed into it .

40
Q

Was there any links between my data sets ,w ere there any anomalies .

A

-Tehre is alink between my bipolar analysis and annotate fieldsketch ,w ehn describig the effectievness of the slpe .
-Bth showing low levels of eriosn , which I have given a +2 , on th bipoalr anaysolis .
-Similarily , the fieldsketch on site 2 , ah annotaitons , s howing ho the slope cn control flooding ..

-Hwoever , there is an anomaly , I have given the groynes an overal score on the bi-polar anysis as a 3 , due to its vulnerbailtiy of eriosion .

-Howver , ny inverted gtph suggest tht overal the groynes wer effective in stopping LSD.

41
Q

Conclusion (1)

A

-Pverall , only two of my coastal defences had a posite score , and thereofre were effective . Rocka rmour 2+ , sea wall 4+ , whereas groynes , sewall and nai ,all had negative scores .

42
Q

Conclusion (2)

A

-Suggeitng tht overall , coastl management strateies are only partially effective at Minster Leas .
-At site three , throguh my annotated field sketch , it si clear that the area is vulenrable to eriosn due to slumping cliffs and the murky water SUGGESTING LTS OF SEDIMENT HAS BEEN WASHED INTO THE SEA .
-tHIS I BECAUSE , there are no defences , stopping the process s there is no point .
-OST COST EFFECTIVE IF YOU ALLOW THE HSORE TO EVLVOE NATURALLY .

43
Q

Conclusionn (3)

A

-In site one and two , erosion was less evident , from the annotted field sktech , especialy in site 2 , as thre wer lots of defences (such as groynes , sea walls and regrded slope ) , the defences had ti be effecgtie , because along the promenade , I had dw rcrrtvdir euqpiment ,.
-SUgeesting theya re confident , with their manaegement stragteis ,a s they wont b geet destroyed by glooding .

44
Q

Conclusion (4)

A

-Moreoever , althogh I have amrked down the groyne and sewals as ‘-‘ , for protectoin agaisnt erosion , ecuad I aahd givent he graded slope a + , it didn’t matter if the other two defences weren’t as effecivt becuase the regraded slope can hadnle mos tof hte impact .

-Thereofre with a + , on the bipolar naayss , for proectiona gsisnt erosion , and + for good life expectancy , ad low cost , regraded slppe is the most evffective protecton agsint erosion in m topinoin .
-And the lest effective of the groynes , with being vulenbale ot eriosn , and unable to control costal floodign with a score of -.

45
Q

Additional data , which would help with our enquriy .

A

-The roundenss ofht epebble s, near the sea, in the middle , adn near to the land .
-Cliff angle , and lONG SHORE DRIFT , seeing hwo an object flaoted from east ot wed t, and ho long .

46
Q

Furhter lines of enquiry ?

A

-Hwo does the beach rpofiel vary along the coast .
-How do pebbles erode along the beach .
