Aim of Study 1. To study the effects of constructive and destructive wave processes on coastal landforms development 2. To determine the influence of the local rock and structure on the development of coastal landforms.

Location of Study The data was collected at Robins Bay St. Mary, Jamaica.
2
Method of Data Collection The Data Was Collected on March 30th 2011 at Robins Bay St. Mary. Tables, along with labeled diagrams, were used to present the data.

Wave Action The power of waves is one of the most significant forces of coastal change. Waves are created by wind blowing over the surface of the sea. As the wind blows over the sea, friction is created - producing a swell in the water. The energy of the wind causes water particles to rotate inside the swell and this moves the wave forward. The size and energy of a wave is influenced by: y y y how long the wind has been blowing the strength of the wind how far the wave has travelled (the fetch)
Waves can be destructive or constructive. When a wave breaks, water is washed up the beach - this is called the swash. Then the water runs back down the beach - this is called the backwash. With a constructive wave, the swash is stronger than the backwash. With a destructive wave, the backwash is stronger than the swash.
