The formation of landforms over one or more of these time scales should be related to processes. A new study suggests that exposure to coastal environments can play a significant role in boosting human health and well-being, due to the therapeutic effects marine and coastal landscapes have. the changing role of wind with distance inland Davis, R.A., 1989. Superimposition of circles makes interpretation difficult and confusing In this study, a fire-prone plant community (Triarrhena lutarioriparia L. Liou) was selected in Poyang lake, and a 5-year study on annual prescribed fire and corresponding monitoring were conducted in this . Soft engineering - this involves working with nature by using natural materials or allowing nature to take back areas. AO1 Focus is on differences in deposition rather than comparison of deposition and erosion. Traeth Mawr, 17. Journal of Coastal Research, 14: 407417. In this study, we attempt to address this issue by simulating the spatial interactions among natural hazards, ever-increasing human activities, and social vulnerability in the south coast of the Bohai Sea, China. AO1.1 a.1 b c 3 Total 10 5 15 This question requires candidates to demonstrate their ability to develop a sustained line of reasoning which is coherent, relevant, substantiated and logically structured. Human activity along the coast has both positive and negative impacts on the natural environments. Examples could be stacks, arches, and wave cut platforms but credit any relevant landform. (a) Use Figure 2 to describe the varying impacts of coastal erosion over time. AO2 Encyclopedia of Earth Sciences Series. An examination of human impacts that increase or decrease erosional processes Variation of expense with what is damaged Knowledge and understanding of the processes operating over a time scale of seasons - variations in wave type, variations in wind, flood pulses There have been many disastrous chemical spills at sea and from industry on land, affecting animals immediately via ingestion, or long term, in changes to reproduction cycles and other biological processes. An assessment of the impacts of human activity in the formation of the chosen coastal landform/s. An examination of the scale of the role of erosional processes Beaches move back and forth onshore, offshore and along shore with changing wave conditions. Beside this Harmful Algal Bloom (HAB) is caused due to increasing surface run off in form of industrial wastage and major brick factory beside this coastal region. The environment on the other hand is inanimate and exists by means of . As our population approaches 7 billion people, the effects of human activities on the ecosystem, including the water, air, land and the life that we share the world with, are almost immeasurable. Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in AO2 content encompasses the application of knowledge and understanding to examine the role of longshore drift in the formation of one landform of coastal deposition. Knowledge and understanding of the positive impacts of these processes on human activity e.g. This leaves the sand dunes more susceptible to erosion causing blowouts and disrupting the succession of vegetation in the area.
