The foreshore is most affected because it is where the waves are most frequently hitting that part of the sand dunes which means that erosion will occur faster there. In the North Atlantic, there are more severe storms, population and development pressures, and regional-scale impacts such as climate change. An advantage of coastal developments is the economic gains that are generated because coastal areas are popular tourist destinations. Examples of coastal development that results from human modification of coastal lands is clearing of natural beach habitats to make room for larger beach areas. The preceding answers are all very good. Sand is constantly eroded in one area an deposited in another. Even more minor coastal constructions can transform the seas. . Floating villages have been around for a long time. Reefs are popular tourist locations, and tourist activity in areas around them can cause damage directly or indirectly. Beach armoring on the other hand works to maintain the integrity of the State and local agencies are key players as they have an increased ability Roadcrews try to clear the damaged Highway 12 near Cape Hatteras These effects were related to coastal development and other human-related impacts on the reefs, such as rising sea temperatures, coral diseases, overfishing and aquatic pollution and. Coastal development can cause chronic sedimentation, sewage effluent, industrial discharge, changes waterflow and run off which can harmfully affect coral growth rates and metabolic activities as well as directly kill corals. Lakes), and notes that these areas are becoming increasingly populated. It is not possible to completely stop the power of natural forces from changing the coast. Breakwater at the entrance to Harwich Harbour, looking toward They are effective in protecting cliffs from erosion They can only absorb the energy of oncoming waves. intricacies of the coastal management network are complex, but through them People touch, stand on and directly damage the reefs. The erosion effects the foreshore most out of all the parts of the sand dunes. Artificial coral reefs can also be created from ship wreckage that lands at the bottom of the ocean. Given that land reclamation tiptoes the line between earth and sea, disputes over sovereignty keep lawyers of both very busy indeed. (Chambers, 2007), sand being deposited upon it. Beach renourishment, also known as beach replenishment, is the reason so many beaches still remain in good condition. However, scientists have found ways to try to reduce the damage.
