rock armour/rip rap
large resistant rocks dumped on the beach to break the waves protecting the land and buildings behind it
1 of 30
backwash
movement of water down the beach
2 of 30
swash
movement of waves up the beach
3 of 30
managed retreat
process of leaving land to naturally erode away in the sea
4 of 30
groyne
wooden or concrete barrier across a beach at an angle trapping sediment
5 of 30
gabions
wire cages holding rocks that can be built up to create walls
6 of 30
hard engineering
man-made structures that interfere with coastal processes
7 of 30
soft engineering
natural materials used to interfere with coastal processes
8 of 30
weathering
chemical, physical and chemical breakdown of rocks in situ
9 of 30
erosion
wearing away and breaking down of coastlines by the sea
10 of 30
beach
an accumulation of sand and shingle
11 of 30
headland
land that juts into the sea
12 of 30
revetments
planks which act as breakwaters but allows sand to be carried through
13 of 30
sea wall
wall built in front of the coast for protection
14 of 30
prevailing winds
wind blowing from one direction
15 of 30
beach nourishment
addition of extra sediment to rebuild a beach
16 of 30
beach re-profiling
act of changing the shape of a beach
17 of 30
offshore breakwater
barrier built offshore in which the waves break on
18 of 30
wave refraction
sides of headlands are eroded by waves that refract aroud it
19 of 30
bar
where a spit grows across a bay
20 of 30
hydraulic action
sheer force of the wave hitting the cliff causes parts of it to wear away
21 of 30
solution
corrosive sea water dissolves chalk and limestone making it easily erodable
22 of 30
abrasion
wearing away of cliffs by sediment flung by breaking waves
23 of 30
attrition
rocks and boulders in the sea collide with eachother and break into smaller rounder pieces
24 of 30
biological weathering
breakdown of rock through the action of plants and animals
25 of 30
bay
less resistant rock that gets eroded by waves and found between headlands
26 of 30
chemical weathering
takes place when there is a chemical change in certain rocks
27 of 30
mechanical weathering
disidisintergration of rock without any chemical changes taking place
28 of 30
tetrapods
man made four legged concrete shapes dumped along the coast to protect it
29 of 30
beach recycling
material is moved back to its original position from where it accumulated to
