The Flight Deck building, Collaroy In addition to the houses being unsafe to live in, they are also damaging the beach itself. After large storms over the years, the huge tides and waves have reached the houses.
Floods and storm surges pose a threat to this seaside town. Like the 1953 floods which killed 7 people. Because of the floods, several breakwaters were installed. This has lead up to the wide sandy beach which has retained its Blue Flag award. If there is a flood risk, then the flood gates can be closed.
There is the main point of erosion which is corrasion, attrition, solution and hydraulic action. Corrasion is when waves carry debris (such as rocks, sand and pebbles). This is then hurled against the cliff face as the wave breaks on the cliff this will cause the cliff face to then crack and break off over a period of time. These fragments are then picked up by the wave and hurled against the cliff face; the process repeats itself with the new
Camille eventually strengthened somewhat as it moved more inland bringing major destruction to the state of Virginia with damage to property and life. The track of Camille took it northeast and eventually back into the Atlantic where is regained tropical storm
The producer used the semantic field of not only boats but danger. The producer uses words such as ‘dark’ and ‘buoyancy aids’ in order for the receiver to be shocked and aware of how dangerous taking a boat out into the sea can be. By making them aware of this they’ll be more likely to understand that they need to follow the terms and conditions to ensure their safety. By signing the terms and conditions due to this the producer will have exerted its power. The producer of this text has used imperative lexis.
Runoff Quality of the water flowing from the a\land is critical to the reef’s health. The ones near the mainland are the most damaged because of human activities. The land use activities near the coast increases freshwater runoff and the build up of silt. As more land is eroded by human activities the runoff increases destroying the vegetation. Fertilisers, sewage and pollutants can have direct impact on the coral reefs.
A drawback to the ‘unique’ design of the island could mean that beaches could have cloudy water due to insufficient water movement around the islands, as well as dredging of sea beds. This could turn people off living on the Palm and settle in a more natural beach place where the sea is clean. The concept of coral reefs being destroyed in order to build the island would also not be a fact seen in advertisement brochures. The overall biggest risk with building the Palm would be the Global Warming and rising sea levels which could drown the island. Nakheel has gone to some efforts to prevent this from occurring by building breakwaters but they would be no match for a vicious tsunami.
The tide is high Happisburgh Coastal erosion happisburugh Coastal erosion is when the water and/or wind carry out sediments of land; sediment is rocks, dirt and earth. It happens mostly on beaches and shorelines because they had no vegetation or plants to be a natural protection against the water. People believe that it is just the water that erodes the coast, but both the water and wind are main factors that constantly change the boundary between the land and water. The beach can be affected severely or lightly depending on the lunar tides and the difference in water density. Coastal erosion in Happisburgh Happisburgh is to the east of England and in 2001 had a population of 1,372 in 607 households.
At North Cronulla concrete footpaths were built on existing sand dunes. However, the natural process of sand erosion caused by the waves hitting the beach undermined the pathways and they started to collapse. To halt the erosion large river stones were placed underneath the length of the path to create a base on which interlocking honeycomb shaped bricks were concreted into place. A continuous sloping retainer wall was built that is approximately 330 metres long. The retainer wall has remained in place because it withstands the continual flow of water and wind erosion.
Destructive waves have a stronger backwash and have a weaker swash. Destructive waves erode the beach and it destroys the beach. On that day, we did four different investigations on the Berakas Beach. We were split into groups of five for all investigations. The first investigation we did was the wave
