Seaford, East Sussex
Seaford is a town in East Sussex, England, east of Newhaven and west of Eastbourne.OS Explorer map Eastbourne and Beachy Head Scale: 1:25 000. Publisher:Ordnance Survey – Southampton B2 edition. Publishing Date:2009. In the Middle Ages, Seaford was one of the main ports serving Southern England, but the town's fortunes declined due to coastal sedimentation silting up its harbour and persistent raids by French pirates. The coastal confederation of Cinque Ports in the mediaeval period consisted of forty-two towns and villages; Seaford was included under the "Limb" of Hastings. Between 1350 and 1550, the French burned down the town several times. In the 16th century, the people of Seaford were known as the "cormorants" or "shags" because of their enthusiasm for looting ships wrecked in the bay. Local legend has it that Seaford residents would, on occasion, cause ships to run aground by placing fake harbour lights on the cliffs. Seaford's fortunes revived in the 19th century wit ...

Baymouth Bar
A baymouth bar is a deposition (sediment), depositional feature as a result of longshore drift. It is a bar (landform), sandbank that partially or completely closes access to a bay. Background These bars usually consist of accumulated gravel and sand carried by the current of longshore drift and deposited at a less turbulent part of the current. Thus, they most commonly occur across artificial bay and river entrances due to the loss of kinetic energy in the current after wave refraction.

Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...

Longshore Drift
Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle) along a coast parallel to the shoreline, which is dependent on the angle incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves parallel to the coast. Longshore drift is simply the sediment moved by the longshore current. This current and sediment movement occur within the surf zone. The process is also known as littoral drift. Beach sand is also moved on such oblique wind days, due to the swash and backwash of water on the beach. Breaking surf sends water up the beach (swash) at an oblique angle and gravity then drains the water straight downslope (backwash) perpendicular to the shoreline. Thus beach sand can move downbeach in a sawtooth fashion many tens of meters (yards) per day. This process is called "beach drift" but some workers regard it as simply part o ...

Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Beachy Head
Beachy Head is a chalk headland in East Sussex, England. It is situated close to Eastbourne, immediately east of the Seven Sisters. Beachy Head is located within the administrative area of Eastbourne Borough Council which owns the land, forming part of the Eastbourne Downland Estate. The cliff is the highest chalk sea cliff in Britain, rising to above sea level. The peak allows views of the south east coast towards Dungeness in the east, and to the Isle of Wight in the west. Geology The chalk was formed in the Late Cretaceous epoch, between 66 and 100 million years ago, when the area was under the sea. During the Cenozoic Era, the chalk was uplifted (see Cenozoic Era). When the last ice age ended, sea levels rose and the English Channel formed, cutting into the chalk to form the dramatic cliffs along the Sussex coast. Wave action contributes towards the erosion of cliffs around Beachy Head, which experience frequent small rock falls. Since chalk forms in layers separated by ...

Seven Sisters, Sussex
The Seven Sisters are a series of chalk sea cliffs on the English Channel coast, and are a stretch of the sea-eroded section of the South Downs range of hills, in the county of East Sussex, in south-east England. The Seven Sisters cliffs run between the mouth of the River Cuckmere near Seaford, and the chalk headland of Beachy Head outside of Eastbourne. The dips or swales that separate each of the seven crests from the next are the remnants of dry valleys in the chalk South Downs which are being gradually eroded by the sea. Some of the cliffs and adjacent countryside make up the Seven Sisters Country Park, which is bounded on its inland side by the A259 road, and is itself a part of the larger South Downs National Park. Cliffs From west to east, the sequence starts just east of Cuckmere Haven. The cliff peaks and the dips between them are individually named. Listed below, the peaks are in italics. There are seven hills, with an eighth one being created by the erosion of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Downs
The South Downs are a range of chalk hills that extends for about across the south-eastern coastal counties of England from the Itchen valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate, East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs and includes large parts of the Weald. The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England. The South Downs are relatively less populated compared to South East England as a whole, although there has been large-scale urban encroachment onto the chalk downland by major seaside resorts, including most notably ...

Downland
Downland, chalkland, chalk downs or just downs are areas of open chalk hills, such as the North Downs. This term is used to describe the characteristic landscape in southern England where chalk is exposed at the surface. The name "downs" is derived from the Old English word dun, meaning "hill". Distribution The largest area of downland in southern England is formed by Salisbury Plain, mainly in Wiltshire. To the southwest, downlands continue via Cranborne Chase into Dorset as the Dorset Downs and southwards through Hampshire as the Hampshire Downs onto the Isle of Wight. To the northeast, downlands continue along the Berkshire Downs and Chiltern Hills through parts of Berkshire, Oxfordshire, Buckinghamshire, Hertfordshire, Bedfordshire and into Cambridgeshire. To the east downlands are found north of the Weald in Surrey, Kent and part of Greater London, forming the North Downs. To the southeast the downlands continue into West Sussex and East Sussex as the South Downs. Similar cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grazing Marsh
Grazing marsh is a British Isles term for flat, marshy grassland in polders. It consists of large grass fields separated by fresh or brackish ditches, and is often important for its wildlife. History Grazing marshes were created from medieval times by building sea walls (earth banks) across tidal mudflats and salt marsh to make polders (though the term "polder" is little used in Britain). Polders in Britain are mostly drained by gravity, rather than active pumping. The original tidal drainage channels were augmented by new ditches, and flap valves in the sea walls let water drain out at low tide and prevent the sea or tidal river from entering at high tide. Constructing polders in this way is called ''inning'' or ''reclaiming'' from the sea. Grazing marshes have been made in most lowland estuaries in Britain, often leaving only the river channel and the lowest part of the estuary tidal. In a few cases (such as Newtown Harbour on the Isle of Wight, and Pagham Harbour in West Sus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
