海平面上升已经影响到了新月海滩地区。据观测，该地区在春季和冬季汛期洪水频繁。同样的影响在未来会越来越大。海平面上升正在影响沿海地区。由于海洋驱动力的复杂相互作用，海岸线正在发生变化。由于海平面的上升，新月形海滩及其周边地区的地貌发生了变化。每年海水带走大量的沙子。同样的，新月海滩周围的地标也面临着巨大的风险。由于海平面的上升，可能会造成景观的丧失。由于海平面的上升，可能会形成海崖和沙丘(Nicholas et al . 1996, 301)。这可能是由于一部分的沙子堆积，另一部分的沙子被移走。在这些地区及其周边地区，人们已经注意到泥沙侵蚀的问题。
One of the recent threats which have been recognized for the low level nations in the world is the rise in the levels of sea. There may be a number of locations in the world which are prone to large waves, hurricanes, tsunamis and the floods in the areas closer to the sea. It is estimated that there are around 20 million people, who are living under the risk of high tides and around 200 million people are under the risk of flooding during the temporary. In the recent times the issue of level of risk are increasing more and more. In this research paper, the discussion has been done on the geographical impact of the rise in sea levels in the community of Crescent Beach in British Columbia. This will be a challenge for the government as the region has a high population and it also serves as an important resource for the purpose of recreation. Also it is an important there should be a minimum damage from the rise in sea levels in these regions. It is clear that there is a lot of improvement is required in the technology in order to minimize the impact on sea level. It has been assumed that by the year 2100, there may be a rise in the sea level by 40 to 55 inches in the area of crescent beach. Thus, it is a serious concern.
In this research paper, the discussion has been done on the geomorphic impacts of rise in sea level, the social impact and the economic impacts on the Crescent Beach which is associated with the rise in sea level and the options available for the mitigation of risks for the community.
Rise in the sea level
Geomorphic impacts of rise in sea level at crescent beach
Rise in sea levels has been impacting the area of crescent beach. It is observed that at this region there is a huge frequency of flood during the routine spring and winters. The impact of the same will increase more and more in the future. The sea level rise is affecting the coastal areas. Because of the complex interactions of the driving force of the sea is changing the shore line. Because of the rise in sea level there are geomorphic changes in the crescent beach and the area around the same. A large amount of sand is taken by the water of the sea every year. Also because of the same, there is a huge risk to the landmarks around the crescent beach. There may be the loss of landscape because of the rise in sea water level. Because of the rise in sea level there may be the formation of sea cliffs and dunes (Nicholas et al 1996, 301). These may be due to the accumulation of sand on one part and removal from another. The problem of sand-erosion has already been observed over and around these regions.
