Case Study: Coastal Erosion: Holderness Location| * Holderness is an area of the East Riding of Yorkshire, on the east coast of England. In the north of the sediment cell, glacial till cliffs 3-40 m high ex- tend 60 km along the Holderness coast and are rapidly retreating (recently reviewed by Quinn et al., 2009). . Sediment cell (littoral cell): a linked system of sources, transfers and sinks of sediment along a section of coastline. what is a sandbar - Lisbdnet.com A sediment cell is a stretch of coastline, generally flanked by two conspicuous headlands, where the development of sediment is pretty much contained. Typical littoral cell (Santa Monica Cell) - Sediment sources are commonly streams, sea cliff erosion, gully and bluffland erosion. It is the fastest eroding coastline in Europe. Where an ord is sited the massive injection of beach sediment goes to form the ord's most prominent constructional feature, . however for the Holderness area south of Atwick has in the long term been fairly consistent at just over 1.7m/year. single coastal cell, extending between Flamborough Head . The UK has 11 such cells recognised by scientists (see map). Coastal sediment cells reflect processes operating at a range of scales, but it is the medium spatial and temporal scales (decades to centuries) that are of greatest interest for coastal management. The Holderness Coast Case Study - Internet Geography It is very important for coastal management strategies. 1 ‐ On Holderness map highlight in different colours Imputs, Transfers, Sinks and Outputs. A key component in managing the coast has been the development of Shoreline Management Plans (SMP) which set out a strategy for the coastal management of a section of the coastline. Depletion of sediment as one body gives way to another allows waves to . SMP's seem to follow the sediment cells; these may be divided into the sub- cells. Mappleton Case Study. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. The structure and organisation of the original report, which in effect used a cell/sub-cell sediment budget approach focusing on transport pathways, has been retained. Overview of coastal management in Holderness (area features, erosion, importance of area, management) • Over the entire 52 km of the Holderness coastline, 153 million cubic metres of sediment has been eroded since 1852 • The till cliffs are largely composed of mud and fine sand, and as a consequence <10% of the sediment is retained in the beach/nearshore system to provide protection from future erosion sediment cells, influences on the sys-tem (winds, waves, geology), sources of sediment How human activity intentionally and unintentional causes change in the landscape system - coastal management, impacts on Landform Processes Example . Holderness coast - transfer zone. Case Study: Coastal Erosion: Holderness Coast ... The processes of coastal erosion have been impacting the area for several hundred years. PDF A LEVEL GEOGRAPHY REVISION GUIDE Paper 1: Physical Geography The coastline is a stretch of land of about 50km from the chalk cliffs at Flamborough Head up to Spurn Head, where a large spit protects the entrance to the Humber Estuary. Sediment Cells Coasts can be split into sections called sediment cells which are often bordered by prominent headlands . Human Causes. Clay Erosion PDF A-level GEOGRAPHY PAPER 1 - AQA There has been a net accumulation of mud, sand and gravel within it. On the softer sediment, the crumbling cliffs are fronted by beach-mantled abrasion ramps that decline gradually to a smoothed sea floor. by constructive waves, destructive waves and longshore drift) and . Sediment is carried by the waves along the coastline. Long-term erosion dominates cliffs updrift and reaches rates of up to 2 m year - 1. Tap card to see definition . Holderness Coastline is along the East coast of England, it stretches along for 50km from Flamborough Head to Spurn Head. Coastal erosion can occur in numerous forms: Holderness. Cliff erosion rates have shown a complex pattern of spatial and temporal variation over the past 160 years which reflects interaction of natural processes and human interventions, notably building of coastal defences at Bridlington, Hornsea, Withernsea, Mappleton . The movement of the material is known as longshore drift. Add a key. Sand mining in rivers is a major cause of coastal erosion in many countries. How many villages have fallen into the sea since roman times at Holderness? within Cells 2, 3 and 4 (Motyka and Brampton, 1993). Waves approach the coast at an angle because of the direction of prevailing wind . Sediment cells. • Inputs (sources) — these are principally . -a vast amount of sediment that feeds the sediment cell . Sediment Cells. 2 ‐ Activities 1 and 2 3 ‐ On sediment cells handout highlight the 11 main sediment cells on Uk as shown. Equipment The Jenkinson daily weather type is a useful proxy for UK east coast storminess. The Humber Estuary forms the southern boundary of the sediment cell, acting as a sink for sediment transported along the coast. The lost villages of the Holderness Coast stand as examples of failed accommodation, followed by planned retreat in only a few cases, but mostly forced retreat and sacrifice as the ultimate solution. Spurn head - sink region. * Rapidly retreating coastline. 537). Holderness cliffs down from Flamborough Head to Spurn Head. interference by using groynes and sea. Within each sediment cell, there are inputs of sediment (e.g. Cliff erosion rates have shown a complex pattern of spatial and temporal variation over the past 160 years which reflects interaction of natural processes and human interventions, notably building of coastal defences at Bridlington, Hornsea, Withernsea, Mappleton . Coastal systems geomorphological & coastal processes 3.1.3.2 ANSWERS Q1 The vast majority is of marine origin. Coastal Processes on the Holderness Coast 1. The focus is the east coast of England . To examine the relationship between beach sediment and other factors, for example the size and slope of the beach. Title your handout when you stick it in. The Holderness coast, which extends between Flamborough Head and the Spurn Peninsula at the mouth of the Humber estuary in the East Riding of Yorkshire (Fig. There is a general southern movement of sediment along the Holderness coast with most of the fine sediment being carried offshore and eventually deposited in the German Bight or the Thames estuary (ABP, 1996). Each SMP covers an area of coastline known as a sub-cell within a littoral sediment cell, of which there are eleven on the England and Wales coastline. coastline is further in danger from rise in sea level. As recovery efforts for those impacted by Hurricane Sandy continue, U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane. SMP 1 Scottish border to the River Tyne (Northumberland and North Tyneside . 1), consists . The Holderness Coast is famous due to its history of being one of Europe's fastest eroding coastlines. This paper focuses on coastline position change within a single sediment cell over 150 years where the geomorphology includes cliffs, beaches and saltmarshes. The amount of accretion in Lincolnshire corresponds to around 29% of the volume of sediment\ud eroded from Holderness. Example: Flanborough head - source region. Match. The origin of the sediment is the erosion of inland areas by ice, wind and water as well as sub-aerial processes such as mass movement and weathering. Figure 5 shows the main inputs, transfers and stores within a sediment cell. Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant The Holderness Coast stretches over 50km from Flamborough in the north to Spurn Point in the south. They form due to longshore drift and protect shallow brackish bays or salt marshes behind them. 2 ‐ Activities 1 and 2 3 ‐ On sediment cells handout highlight the 11 main sediment cells on Uk as shown. It is the division of the UK coastline into separate cells, where sediment from one cell does not venture into another. councils have a holistic view bringing together information on coastal erosion and flooding, sediment transport and tides, humans use and wildlife interest, and . Describe Flamborough Head as a coastal unit. This then starves the coast of a sediment source, leading to serious consequences. across a river mouth. The Holderness coastline is located on the east coast of England. They are often determined by the topography and shape of the coastline which directs the movement of the sediment within the cell. [6 marks] AQA 'No amount of coastal intervention by people can halt the natural processes which continue to present 3.1 Biological carbon cycles and the water cycle are threatened by human activity. Holderness Coast Where is Holderness Coast? units. Much of the eroded cliff material is likely to be deposited temporarily into nearshore\ud and offshore sand banks before being redistributed by cross-shore currents. Movement of sediment in one cell does not impact on beaches in another. understanding is the sediment cell. Holderness Coast Sediment Cell 6. From here, there is a drift divide into the Humber and to a smaller degree to the . The result is waves break on to the beach obliquely at an angle of around 45 degrees. Holderness Coast Case study. 3 EFFECTS OF EROSION The effects of erosion are felt along the length of the Holderness coast in different ways and in different magnitudes. * Sub-cell that stretches from Flanborough Head to Spurn Head.

South Bay, Scarborough, Sand Tracking Study 2015. Sediment cells are areas along the coastline and in the nearshore area where the movement of material is largely self-contained. Coastal management case study: Holderness coastline. The key characteristics of sediment cells are as follows. The Holderness coastline is located on the east coast of England. At the specific request of SCOPAC and the South Downs . A sediment cell serves two purposes: Ÿ It is the basic functional unit of the coast. Click again to see term . Sediment movement is relatively self-contained within each sediment cell. the rate of sediment supply to the nearshore system, but it is . Erosion of the soft Holderness cliffs to the North, carried . 2.2 Current wave climate 15 The current wave climate off the Holderness coast is recorded by the Hornsea Di- To investigate the origin of beach material through the study of sediment cells. To compare sediment analysis at beaches in a range of locations and attempt to explain similarities and differences. These changes may then require management in order to mitigate their impacts. The Holderness Coast By The British Geographer Situation The Holderness coast is located on the east coast of England and is part of the East Riding of Yorkshire; a lowland agricultural region of England that lies between the chalk hills of the Wolds and the North Sea. It moves not as a whole but in segments, or bodies. . In some locations, as much as 90 percent of coastal sediment comes from rivers. An understanding of the way in which this system functions allows us to identify the impacts of development Material which forms the beach is called beach sediment, a broad term for sand of all grades, for shingle, pebbles, cobbles, and rocks. Sand is transported along the shore by waves and currents to nourish beaches. The Holderness Coast and physical and human pressures. The coastline of England and Wales is divided into 11 primary sediment cells, with sub-cells within each primary cell. Southwards of the Humber Estuary and the North Sea. SMP chose either of four options: hold the line, advance the line, retreat the line, do nothing. and a closed system of sediment movement in the nearshore bank regime to the south. The most striking aspect of Flamborough Head is the white chalk cliffs that surround it. Warm water moves away from the equator towards the poles), Paris Climate Summit, Cherbourg Penninsula & Chesil Beach, Holderness (Sediment cell number 2, retreating at an average of 2mm per year, Threat of flooding and erosion, Hard strategies being used), Southampton Water (Inputs, Outputs, Rivers, Inputs and outputs balanced), Angle of Dip . Longshore drift continues to deposit material across the mouth of a river which results in the . Mappleton is located on the Holderness Coast of East Yorkshire. The construction of major dams of rivers can trap river sediment behind the dam wall. Spits are formed where the coast suddenly changes direction e.g. Fine suspended sediment is carried offshore in turbid plumes and deposited in deeper water. The Holderness coast is composed largely of 'soft' Quaternary sediments, mainly glacial till, which form cliffs up to 38 m high. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks. Gravity. Holderness Case Study. b) 2 marks per definition one on isostatic change the other on eustatic. Hornsea Mappleton / Great Cowden Withensea Easington Spurn Head Coastal Management along the Holderness Coast Task: Decide which location the satellite image is showing using the descriptions • Complete the table next to the map • Annotate the image: Positives and negatives of that type of management and . 'Coastal process cells are areas within which coarse sediment (sand and gravel) movement is contained.'. The Cell wide reports. 61 littoral sediment budget as a control direction of coastline movement is widely on the 62 recognized and is typically linked to the concept of the sediment (or littoral) cell. Within these sections, the movement of sediment is almost contained and the flows of sediment act in dynamic equilibrium . sediment cell, acting as a sink for sediment transported along the coast. Ideal 63 sediment cells aresections of coast that are relatively self-contained and includedefined 64 sources, transport pathways and sinks of sediment. The complete list of SMPs is below, with the name of the local council or Environment Agency office leading on the plan. Some sediments comes from tidal currents which pick up glacial deposits on the shallow sea floor. Cells.The location and size of these cells is such that coastal . What is a sandbar and how does it form? A sediment cell is defined as a length of Much of the material that forms the spot is derived from the Holderness coast and transferred south by LSD - on reaching the River Humber estuary, the deposited sediment grows out to form a narrow finger of new land (spit)- its curved tip resulting primarily from direct wave action . Sediment budgets may be affected and rates of natural processes may be altered. Holderness coastal sediment cell, stretches 50kms from Flamborough Head (N) to Spurn Head (S) at Humber Estuary. Sand bar: A strip of land formed by deposition of sediment via longshore drift or at the mouth of a river.Barrier Island:- A sandbar disconnected from the land. Yes. Highlights Trends in the balance of sediment supplies and sinks in a littoral cell are examined. How is a spit formed a level? Where is the source in UK sediment cell 2? - Since the last ice age, The Wash has been a sediment sink. Flamborough is the headland that forms the most northerly point of the Holderness Coast.
