How efective is coastal management and Minister Leas
Health +safety
-Nobody is to go in the sea .
-Stay in groups - don’t run off
-Resobsile or equipment damage +-work int teams .
Why is Minnisteal suitable for this inevestigation .
-Proximmity , ckose to shhol .
-Allthe different bach profiles include .
What are the pontenital rsisks when carryig out fieldwork ,,
SCOURE OUT OF 10 10 VERRY RISKY 1 LOW RISK
Taffic - 4 0 look left+right , don’t runa cros the road .
-Drowining -3- Stay 2m away from the seas
-Sun burn - 7 - suncrscnreen , hats .
What was site 1 ?
BARTONS POINT .
-HAD RECRUVED SEA WALL - to portect main road .
-ROCK ARMOUR - aborbs waves energy , reducing erosiiono fthe costilin
-CYCLE PATH - tourist facilitities
-STREEET FURNTITURE - suggestign tourism
c02 emitted - rocks ll the wy from norway .
EVALUTATION OF DEFENCES HERE S1
+2 ON rockarmour .
What was Site 2 ?
Minnistleas
-Retaining wall - keep the embankment in place . Preventing mss movmemnt , keeping soil in plac .
-cuvred emankment not naturala , shhallow angle promenande .
-exercise equip for public nd stiars easya cess to beack ,
Groynes stop long shore dirft .
EVALUATION OF DEFENCES IN S2 ?
-sea wall - - 0.2
groyens - -0.6
Refraded slope- 0.8
What was site 3 ?
EAST end Cliffs .
-oN TOP OF CLIF GTHERE IS farm +carvan park
-Cliffs aremade out of softy clay - the cliffs have SLUMPED - CURVED PROILE .
-Full of old its of defecnes rubbig +twigs .
EVALUTATION OF DEFENCES IN S3 ?
NO active intervention - -0.6
ADDITIONAL METHODS
-BEAHC PROFILE OF eAST END CLIFFS , AND mINISTER lEES .

pEBBLISE SZIE AND SHAPE .
What might affect our results .
TIME OF DAY - morning calmer nightime mroe violent waves .
Tide - mesauring at high tide different to measuring t low tide .
-PEER REVIEW - TO FIX BIAS ,
-windspeed -FASTER windspeed MORE WAVES - high tide , lsd also increases ..
-AREA OF BEACH WE MEASURED - larger area , more of a range of pebbles ,s moller area , a smoler range of pebbles ..
How does Minnistleas linkt o what I have studied ?
-hard engineerign strategies
-Beach proiles - depostion
-Mass movment - cliff slumping
-LSD
-EROSION
-WAVES .
ALSO LINKS TO HUMAN GEO
-Cost
-Benefit anaylsis
What is Primary data?
-The advantages ?
-The disadvantages ?
Primary data is data we collected ourselves ,
-We rememebr it and trust it as you collected it yourself for the purpose , and it is up to date .
-Could be nacurrate (not professional ) , DATA IS ONLY TRUE FOR THAT DAY .
What is secondary data ?
-The advantages ?
-The disadvantages ?
Soemoene else has found the data by research .
-A lot more data - with los more sources and views on different people .
-Old out of date , can’t tell if its biased (depend who wrote it .
SAMPLING -Systematic
-The advantages ?
-The disadvantages ?
To meausre soemthing every so often (pebles form beginnig , middle and end of beach ) .
-Sytematic , elimates bias and is accurate as things are evenly spaced out .
-Missing changes between regualr inervals (changes between berms .)
SAMPLING - Random
-The advantages ?
-The disadvantages ?
-Randomly choosing things (pebbles picked up ) , or random number generator .
-Random - elimating bias
-Not accurately representing the whole area (Ignoring smal / large rocks .)
SAMPLING - Pragmatic
-The advantages ?
-The disadvantages ?
Targeting certain location to see coastal management strategeis .
-praitcal and acessible for us .
-Didn’t see anythign suprising , so cold have missed s it is b ias , or what your eacher told you to see , DIS WHAT WE USED
what does
qualititive and quanitiave mean .
qualititive - descriptions , photos .
quantiitave - numbers and data .
FIELD WORK TECHNIQUE 1 - BIOPLAR SURVERY OF THE COASTAL DEFECNES
-both qualitative +quantittave data
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 .
Justification of Bi-Polar Method .
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 .
FIELD WORK TECHNIQUE 2 -HEIGHT OF THE BEACH EITHER SIDE OF THE GROYNE .
-Quantitive
-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 .
Justification of groyne height ?
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 .
FIELD WORK TECHNIQUE 3 - FIELD SKETCH
Qualitiave
-Draw a view of the site , inclduing informtion about land duse , coasal defen es , geenrl information and apperance of the coast .
