As floodwater carries material from the eroded . Nevertheless, it is still unclear how S. alternation invasion affects the carbon storage capacity of coastal wetlands as carbon pools through bacterial changes. [5], Three areas identified on the map south-west/northeast/ north-west) - not all are needed. Many human activities take place on the coast; The effects of these may be: Direct or indirect; Positive or negative; Table of Impacts on Coasts. [5]. The drift line is formed by the dead seaweed and other aquatic plants. (a) Use Figure 2 to describe the varying impacts of coastal erosion over time. Ability to show change over time (Increase in incidence of) destructive waves [1], increases energy/power [1] leads to greater backwash [1] removes sediment from the coastline [1] and increases shoreline retreat. [5], chalk cliffs steeper than clay and sand, 3. Suggest one reason for the variation in the importance of wind erosion. Such attempts to control the nature of changes on the beach are among the more negative impacts from humans. This provides the stability necessary for plant growth. All points on scale? AO2 the importance of erosional processes or sub-aerial processes The extent to which associated factors such as mass movement, marine erosional processes, geological factors etc. (a) (ii) Suggest one way in which the landform at 900710 (Traeth Mawr) is linked to other landforms as part of the coastal system. The first reason why the beaches are eroding is because of rock jetties. An assessment of other processes Some of these are a result of direct acts of development and others are indirectly the result of these activities. The growing global population has lead to urbanisation which has had intentional and unintentional impacts on the landscape. Assessment of positive impacts over time - increase or decrease The whole of the east coast of the USA used to bloom with trout. Overstrand is the only site with mudflows Certain fishing practices not only contribute to overfishing of their target species, but also damage the environment by dredging the seabed or catching other species that are thrown back dead. (a) Use Figure 2 to describe the pattern of wave energy. Usefulness of Graphs: (a) Use Figure 1 to describe two distinctive landforms of this coastal landscape. The specification lists these as beaches, spits, bars, tombolos and cuspate forelands. AO2 Aeolian Transport is the first process of coastal dune formation and involves the movement and weathering of sand particles behind and along the shoreline. Give your answer to 2 decimal places. 3.6 billion People live near or around a coast. Headland has developed Research shows that underwater noise from construction, shipping and naval vessels significantly impacts the natural behaviour of cetaceans and many other marine species. There are even implications now as they add more sand. Answers may conclude that longshore drift has a major part or variable influence on the development of selected landform(s). Stability of Dunedin and Hurricane Passes, Pinellas County, Florida. Knowledge and understanding of conditions and process of deposition Having said this, physical factors also have significant impacts across coastal landscapes. Wave cut platforms South West Wales has limited number The effects of human activity on coastal landscape. examination of coastal configuration - more deposition taking place in heads of bays, spit formation Human activities shape the structure of landscapes in different ways and hence modify animal communities depending on the type and intensity of these activities. An assessment of the relative importance of longshore drift When answering 8 mark questions on usefulness and limitations need go through: Limitations: 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. 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. This means there is less available dissolved oxygen for native sea life, which can negatively impact biological processes. AO1 [5], Expensive overall People love living near the beach. Accept both routes. 2. -Use of colour, interpretation easy? Dont include personal or financial information like your National Insurance number or credit card details. The content will depend upon the landform(s) chosen and may include: examination of supply of sediment - some places have greater inputs of sediment from rivers, cliffs etc reference to conditions of formation - depth, light, currents The increase in the use of fertilisers for agriculture and warming ocean waters has contributed to eutrophication of the Ocean in certain areas of the world. natural colonization of dune systems to halt erosion Landform/s will be clearly identified and must be erosional. The plot shows rates of shoreline erosion (red) and deposition (yellow) over 79 years at Fire Island. 15. 6. Human impacts along the coastal zone are numerous, widespread in kind, and typically detrimental to the environments . ), Coastal and Estuarine Environments: Sedimentology, Geomorphology, and Geoarchaeology. https://doi.org/10.1007/1-4020-3880-1_175, DOI: https://doi.org/10.1007/1-4020-3880-1_175, eBook Packages: Earth and Environmental ScienceReference Module Physical and Materials Science. Concerns arising from the pollution of coastal and marine waters from land based sources are well established. the importance of time scales in the continuing development of the landform Sand dunes act as a natural barrier against coastal storms and beach erosion caused by strong, destructive wind and waves. This erosion may be very apparent or seem to have happened overnight when it happens due to a large storm or extremely high tide. Many time a maritime forests will form on secondary dunes. the extent to which there has been a changing focus of coastal erosion as sediment is trapped by groynes dredging of sands and gravels. Possible approaches may include: Soft engineering - this involves working with nature by using natural materials or allowing nature to take back areas. [5], This is a high energy coastal environment characterised by erosion, high wave activity, exposure to prevailing winds and a long wave fetch. Focus is on differences in deposition rather than comparison of deposition and erosion. Richard A. Davis Jr. . Coral reefs debris protects base of cliff from erosion An examination of human impacts that increase or decrease erosional processes Location 1 have steeper decline/rate of erosion This may include: Impact of human activity on vegetation across a sand dune complex, Interrelationships between vegetation, soils & the changing role of wind with distance inland -Infrastructure The fact that the business world and the preservation world are on the same page is a good indicator that maintaining beaches are important for both people and animals.

[5], greatest in Newport (b) Explain why wind is important in the formation of coastal sand dunes. PubMedGoogle Scholar. e.g. This is a preview of subscription content, access via your institution. [2], linear clefts in a cliff / narrow inlet, 4. (a) (i) Use Figure 1 to suggest how mass movement is influencing the development of this coastal landscape. Ease of construction * The sand dunes on the beaches. This means there is less available dissolved oxygen for native sea life, which can negatively impact biological processes. Orientation of the coast - some sections of coastline may be exposed to stronger winds It is found that the activities occurring on . The content will depend upon the impact chosen and may include: Protection of cliffs by a variety of management strategies - groynes, sea walls etc. period of time have increased the size of the beach. positive impacts on beaches and tourism generated by deployment of groynes leading to increased erosion and negative impacts further down the coastline. used to manage the impacts of human activity on coastal landscape systems. Your answer should include: Swimming / Living / Sunbathing. Trembanis, A.C., and Pilkey, O.H., 1998. [10]. (b) Discuss the view that coastal processes have a mainly positive impact on human activity. Development of barrier islands accessed by these causeways resulted in various types of construction that have negatively impacted on the coastal zone. This has been successful in reducing the amount of sand that is drawn out to sea. reference to types of reefs - fringing, barrier, atoll There graph shows distinct zones that could be used to identify patterns. When water and wind batter the shoreline sediments are carried out to sea and deposited on the sea floor or at other points along the coastline. The content will depend upon the landform(s) chosen and may include: Harbors and the navigational channels leading to them have resulted in some problems for estuaries. You have rejected additional cookies. [6], Generally increased erosion over time in the south of the photography (reference to dates) Spartina alterniflora is considered an invasive species that has affected the biogeochemical circle of carbon in coastal wetlands around the world. An examination of other time scales [5], The development of the coastal landscape can be seen from both an erosional and depositional viewpoint. Beaches like, Brighton beach, bells beach, Florida beach, etc, used to be plain. Humans interact with the world around us every day, but some of our actions are more harmful than others. - parts of mangrove furthest from low watermark have less erosion (1). Shore Protection Manual, Volume 1. AO2 the role of physical objects at the strand line An examination of the relative role in different locations Now the coast has been fished out. https://doi.org/10.1007/978-3-319-93806-6_175, Shipping restrictions may apply, check to see if you are impacted, Reference Module Physical and Materials Science, Tax calculation will be finalised during checkout. [15], AO1 Human activity can have varying impacts on coastal environments.
