It was not long before attempts to control erosion resulted in various types of structures such as jetties, groins, and seawalls. -Mouth, Take turns and answering questions. Management of drumstick barrier islands. AO2 Candidates should demonstrate application of knowledge and understanding through an examination of the extent to which one coastal management strategy has been successful. [3]. Knowledge and understanding of the positive impacts of these processes on human activity e.g. Assessment of the positive impacts of human activity in different places within one location or between locations There are 4 key areas which have affected the coastline: Its common in parts of the UK for Crowded Coasts to be used as a term, Many people who work in London can no longer afford housing there, so some commute in from coastal towns and cities (Brighton). [3], definition of fetch [1 max] Variation in expense with location (a) (ii) Suggest how lithological factors have influenced the development of the cliffs shown in Figure 1. Check benefits and financial support you can get, Find out about the Energy Bills Support Scheme, Department for Environment, Food & Rural Affairs, last year designating a further 41 Marine Protection Zones. Recognition that the role of marine processes can vary for the same landform between locations. Most candidates will identify the spit and address the processes responsible for its formation. [5], All have landslides as the highest % We also use cookies set by other sites to help us deliver content from their services. meltwater moves to oceans In the 1940s seawalls and groins and even some small jetties were built to protect the properties on the beach. In: Finkl, C.W., Makowski, C. (eds) Encyclopedia of Coastal Science. Possible approaches may include: People love living near the beach. Distances between collection points? [8], AO1 Material from beach can be used to erode cliffs/WCP Ability to show change over time Well send you a link to a feedback form. Location 2 shows less fluctuation in rates of erosion Relevant responses may include: By the time new sand was brought to the beach in 1991 to replenish what was eroded, there was hardly anything left. Human activities shape the structure of landscapes in different ways and hence modify animal communities depending on the type and intensity of these activities. The sandy beach consists of two zones, the swash zone and the drift line. There are several reasons why the coast at Holderness is eroding so quickly: Bridlington is protected by a 4.7 km long sea wall . the extent to which the strategy has modified erosion or deposition issues Ability to pick out anomalies CERC, 1984. Correspondence to The drift line is formed by the dead seaweed and other aquatic plants. Variation of expense with what is damaged This may include: Superimposition of circles makes interpretation difficult and confusing 271 million recreational visits are made to the coast each year. fall in sea level (slowly/over a long period of time) South West Wales has limited number This is more than half the worlds population. 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. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. (a) (i) Use Figure 2 to analyse changes in wave height for the three mangrove forests. Major cities like New York are right next to the sea. The specification identifies the following landforms as depositional - beaches, spits, bars, tombolos and cuspate forelands. Knowledge and understanding of conditions and process of deposition Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. building of groynes or dredging could affect depositional rates, 8. 9.4 Coastal landscapes and processes (The Earth's crust is modified by . the extent to which there has been a changing focus of coastal erosion as sediment is trapped by groynes A number of forces continue to seriously affect our natural water resources. The human impact on the environment is the sum of all activities and behaviors that create both positive and negative changes that affect the Earth's sensitive ecosystem. [15]. [8], AO1 Field Sketches: description of suspension, saltation and traction with link to grain size Whitmore Stairs Low energy characteristics: geographical variations in success Candidates demonstrate application of knowledge and understanding to evaluate the extent to which coastal processes (and their associated landforms) impact positively on human activity. You can also search for this author in lithological factors or structural geology of the area. Floods Cause Sedimentation and Erosion Floodwater can also alter the landscape, for instance, by eroding riverbanks and causing them to collapse. AO2 Wetlands are constantly adjusting to disturbances occurring within them and within the surrounding landscape. debris fan at foot of the cliff (b) Discuss the view that coastal processes have a mainly positive impact on human activity. 2. The Great Barrier Reef is under threat from a range of pressures with a major one being deteriorating water quality due to pollution from adjacent land use. Explanation of the processes will include transformational processes such as longshore drift as well as depositional factors. Midnight Pass, Florida: inlet instability due to man-related activities in Little Sarasota Bay. e.g. There are four main processes of erosion along the coast. 2. This erosion may be very apparent or seem to have happened overnight when it happens due to a large storm or extremely high tide. Human activities add another layer of complexity to the natural processes of coastal lands and materials. [2], linear clefts in a cliff / narrow inlet, 4. - parts of mangrove furthest from low watermark have less erosion (1). Overstrand has highest water erosion, 16. An examination of the role of one marine process in relation to other marine processes in the formation of one or more landforms. This present study is focusing on the understanding of morphological dynamics on coastal region, long-term sediment transport, turbidity distribution pattern, impact of sediment transported pollutants etc. PubMedGoogle Scholar. Knowledge and understanding of the characteristics of identified landforms that are linked to this scale and their link to process. AO1 content encompasses knowledge and understanding of one management strategy. The content may vary according to the landform but may include: How do humans use the coast. Around the foreshore of both Long Beach and Nutgrove Beach, rocks have been added to the foreshore to prevent further erosion of the beach. Dams built for flood control and water catchment along the rivers leading to these coasts inhibit the transport of large grained . These activities may have direct or indirect effects on our changing coasts. An assessment of changes over time (2019) suggests that climate change is currently by far the most important stressor for ocean and coastal ecosystems.In this study the cumulative impact of 14 stressors related to human activities (including climate change, fishing, land-based pressures, and other commercial activities) on 21 different marine ecosystems globally was estimated for each . Long Island is famous for its sandy ocean beaches. 03.4 Assess the relative importance of weathering and erosion in the development of coastal landscapes. Coral reefs (b) Examine the role that wind plays in the development of a coastal sand dune. The government has taken steps to expand its Blue Belt of marine protection for Britains overseas territories and its own coast, last year designating a further 41 Marine Protection Zones, protecting species and habitats such as the rare stalked jellyfish and blue mussel beds. As an important wetland with international significance in biodiversity conservation, Poyang Lake is under severe pressure from increasing human activities, such as prescribed fire. That means the choices we make can have a positive or negative impact on the Ocean. Overstrand is the only site with mudflows The content may vary according to the landform but may include an examination of: Also a great place to retire examples include Bournemouth and Blackpool. (a) Use Figure 2 to describe the varying impacts of coastal erosion over time. Knowledge and understanding of other processes that may form selected erosional landform - transport, deposition Spartina alterniflora is considered an invasive species that has affected the biogeochemical circle of carbon in coastal wetlands around the world. In: Stauble DM (ed) Barrier Islands: process and management. New York: ASCE, Coastal Sediments 87, pp. The Evidence Statement was reviewed by a steering group of experts from Cefas, Defra, Marine Management Organisation, Plymouth Marine Laboratory, The Calouste Gulbenkian Foundation, University of Aberdeen, University of Exeter, and University of Hull. Professor Nicola Beaumont, Head of Science for Sea and Society at Plymouth Marine Laboratory, said: Our research demonstrates that marine and coastal areas play an important role in supporting peoples well-being. -+ shows change and that the angle of the line is able to indicate rate of change. An examination of changes over geographical space in the formation of the chosen coastal landform/s. Knowledge and understanding of the characteristics of one landform of coastal deposition Development of barrier islands accessed by these causeways resulted in various types of construction that have negatively impacted on the coastal zone. isostatic recovery takes place (slowly/over a long period of time) This means there is less available dissolved oxygen for native sea life, which can negatively impact biological processes. Use of colour in key Both show periods of increase/advancement The data that has been collected by both parties, thus far will hopefully bring a more cost effective and more long term solution for beach replenishment. The sand is then pulled out to sea where it forms a sand bar. Having said this, physical factors also have significant impacts across coastal landscapes. the extent to which modification of processes operating in a coastal environment has been successful fetch controls the size of the waves They are a vital part of maintaining our beaches as they absorb the impact. (a) (i) Calculate the values of the highlighted cells, A, B and C in Figure 2. (a) (i) Compare the characteristics of the coastal landscapes shown in Figure 1. Some places will warm much more than others, some regions will receive more rainfall, while others are exposed to more frequent droughts. Comprehensive introduction to human-landscape interactions from preindustrial to postmodern eras.
