Sea Walls are an example of Happisburgh’s coastal defences. They reflect the energy of the waves back into the sea and work best at high tide. But as the wave backwashes; it erodes the base of the wall. This area weakens and could eventually collapse A sea wall will be necessary at a large beach‚ as the sea wall will come into actions during high tides and storm surges Cost= £2000-£5000 per metre Timber Groynes are mainly used to act against long-shore drift. They do this by interrupting the sediment’s

The western Florida Coast has been abused in the number of permits approved for large upscale buildings. The popularity‚ beauty‚ and comforting weather during winter makes this place perfect for tourism. The problem is that the buildings reduce the beaches ad many construction sites extract coastal sand for their projects. The coastal erosion that affects my hotel are both

Coral Reefs Last week I started to work on my research about coral reefs‚ and I realized how important they are. Coral reefs are the most various and beautiful of all nautical habitats. However‚ it’s colorful plants and there are three different kinds of coral reefs. In my opinion‚ I think coral reefs should be preserved instead of being victim by tourists for their own benefits. They will inevitably demolish coral reefs. In this essay I will mention two things; facts about coral reefs and why

Coral Reef Ecosystem Coral reefs are complex and diverse habitat. Perhaps one of the most interesting and colorful ecosystems to be found in the marine environment. They are very unique in many ways. Coral reefs play many important roles in the marine world. Lots of different sea life rely on reefs for habitat and sources of food‚ including some endangered species. (Yasutake‚ 2007) The reef we will be discussing is the great barrier reef of Australia. This is the largest reef in the world

Coastal Processes Coasts are shaped by the sea and the action of waves. Waves act in different ways‚ through the processes of erosion‚ transportation and deposition. Coasts: A coast is found where the land meets the sea. Coasts undergo change due to coastal processes and (as with rivers) there are main processes at work: Erosion Transportation Deposition Each of these processes involves the power of the sea and the effect of waves that are carried to shore. However other factors also

decreased drastically. Coral reefs are home to more species than all other marine environments‚ and many other species rely on the coral reefs for their own survival. Today coral reefs face multiple threats such as pollution‚ unsuitable fishing practices‚ global climate change‚ and other human activities. If humans don’t take action to conserve and improve the conditions of the oceans the coral reefs will suffer. There are many factors that contribute to the death of coral reefs. One of the major factors

Bio 9/12/10 Coral Reef Biome Though not considered a major biome‚ coral reefs qualify by definition. Coral reefs are marine ecosystems located within clear‚ shallow water. These reefs require water between 25 and 31 degrees Celsius‚ and do well in water with a salinity of 34 and 37 parts per 1000. These conditions are most often found within 30 degrees latitude of the equator‚ or in other words‚ the tropics. As the name suggests‚ corral reefs are formed by colonies of coral polyps.
