Coasts: A coast is a part of land which adjoins to or is near the sea. They are used by people in various ways which include fishing, industry, tourism and transport. Local residents, Councils and Environmental groups all have interests on how these areas should be managed and protected. This can lead to a conflict or disagreement. Waves: Waves are created when the wind blows over the sea. The size and energy of these waves is dependent upon three factors: -The fetch (which is the distance that the wave has travelled) -The strength of the wind -How long the wind has been blowing for A long fetch (like one of 8,000 km) will result in a large powerful wave, whereas a short fetch of less than 200 km will produce a small wave. The strength of the wind similarly affects the waves produced, and a larger wind force will produce bigger waves than a smaller one will. If the wind has been blowing for a longer period of time, the energy of the wave will increase as it has had a l
