Aim of Study 1 ) To study the consequences of constructive and destructive influx processes about coastal landforms development installment payments on your To determine the affect of the local rock and structure on the development of coastal landforms.

Location of Study The data was accumulated at Robins Bay St . Mary, Discovery bay, jamaica.

Approach to Data Collection The Data Was Collected about March thirtieth 2011 in Robins Bay St . Jane. Tables, along with tagged diagrams, were used to present the data.

Wave Action The power of waves is one of the most important forces of coastal modify. Waves are manufactured by wind blowing over the surface from the sea. Because the wind produces over the marine, friction is created - creating a swell in the water. The energy of the blowing wind causes drinking water particles to rotate within the swell which moves the wave ahead. The size and energy of the wave can be influenced simply by: y con y the length of time the wind have been blowing the strength of the wind what lengths the influx has journeyed (the fetch)

Waves can be destructive or perhaps constructive. Each time a wave fails, water is definitely washed up the beach -- this is named the swash. Then the normal water runs down again the beach -- this is referred to as the backwash. With a positive wave, the swash can be stronger than the backwash. With a destructive influx, the backwash is more powerful than the swash.

Destructive Surf Destructive Surf is a plunging wave, using a short wavelength, a high rate of recurrence (13- 12-15 per minute) a high crest. Backwash significantly exceeds swash. Destructive waves comb seaside material seawards.

Figure two showing Destructive waves. This wave was present at all locations.

Positive Waves A decreased frequency (6-8 per minute) spilling trend, with a very long wavelength and a low crest, running carefully up the beach front. Swash significantly exceeding the backwash (which is decreased by percolation), leading to deposition.

Figure three or more showing Positive waves. This kind of wave was present in Don Captain christopher Cove and Peytons Cove.

Cave

Caves occur when surf force their particular way into cracks in the cliff deal with. The water contains sand and other materials that grind aside at the mountain until the splits become a give. Hydraulic action is the predominant process.

Level A V-shaped cut or perhaps hole in the bottom or perhaps edge of your surface, normally a cliff. This is created after repeated beating of waves, damaging, on the side of any cliff.

Headlands

Headlands are shaped when the sea attacks an area of coast with switching bands of hard and soft mountain. The groups of smooth rock, including sand and clay, go more quickly than patients of more resistant mountain, such as chalk. This leaves a section of land jutting out in the sea called a headland.
