Submergent Coastline
Submergent coastlines or drowned coastlines are stretches along the coast that have been inundated by the sea by a relative rise in sea levels from either isostacy or eustacy. Submergent coastline are the opposite of emergent coastlines, which have experienced a relative fall in sea levels. Many submergent coastlines were formed by the end of the Last Glacial Period (LGP), when glacial retreat caused both global sea level rise and also localised changes to land height. Features of a submergent coastline include rias, which are drowned river valleys and estuaries, and fjords, which are drowned glaciated valleys. Notable and illustrative examples of submergent coastlines include: * Western Norway, famed for its many fjords created by sea level rise at the end of the LGP. * The Western Coastal Plains of the Indian subcontinent, which includes the estuaries of the Narmada and the Tapti Rivers. * Southern England and South Wales, caused by a "see-saw" reaction to uplift to the ...

Tapti River
The Tapti River (or Tapi) is a river in central India located to the south of the Narmada river that flows westwards before draining into the Arabian Sea. The river has a length of around and flows through the states of Maharashtra, Gujarat and Madhya Pradesh. It flows through Surat, and is crossed by the Magdalla, ONGC Bridge. On 7 August 1968, before the construction of the Ukai Dam to bring its waters under control and provide hydroelectric power, the Tapti River overflowed its banks during heavy rains during the monsoon season. More than 1,000 people drowned in the flood, and the city of Surat was submerged beneath 10 feet of water for several days. After the floodwaters receded, at least 1,000 more people died in Gujarat during a cholera epidemic from the contamination of the drinking water. Its basin covers the parts of Madhya Pradesh, Gujarat and Maharashtra. Course The Tapti River rises in Multai, in Madhya Pradesh, and has a total length of around . It is t ...

Dalmatia
Dalmatia (; hr, Dalmacija ; it, Dalmazia; see names in other languages) is one of the four historical regions of Croatia, alongside Croatia proper, Slavonia, and Istria. Dalmatia is a narrow belt of the east shore of the Adriatic Sea, stretching from the island of Rab in the north to the Bay of Kotor in the south. The Dalmatian Hinterland ranges in width from fifty kilometres in the north, to just a few kilometres in the south; it is mostly covered by the rugged Dinaric Alps. Seventy-nine islands (and about 500 islets) run parallel to the coast, the largest (in Dalmatia) being Brač, Pag, and Hvar. The largest city is Split, followed by Zadar and Šibenik. The name of the region stems from an Illyrian tribe called the Dalmatae, who lived in the area in classical antiquity. Later it became a Roman province, and as result a Romance culture emerged, along with the now-extinct Dalmatian language, later largely replaced with related Venetian. With the arrival of Cr ...

Milford Haven
Milford Haven ( cy, Aberdaugleddau, meaning "mouth of the two Rivers Cleddau") is both a town and a community in Pembrokeshire, Wales. It is situated on the north side of the Milford Haven Waterway, an estuary forming a natural harbour that has been used as a port since the Middle Ages. The town was founded in 1790 by Sir William Hamilton, who designed a grid pattern. It was originally intended to be a whaling centre, though by 1800 it was developing as a Royal Navy dockyard which it remained until the dockyard was transferred to Pembroke in 1814. It then became a commercial dock, with the focus moving in the 1960s, after the construction of an oil refinery built by Esso, to logistics for fuel oil and liquid gas. By 2010, the town's port had become the fourth largest in the United Kingdom in terms of tonnage, and continues its important role in the United Kingdom's energy sector with several oil refineries and one of the biggest LNG terminals in the world. Milford Haven is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingsbridge Estuary
The Kingsbridge Estuary (also, erroneously, known as the 'Salcombe Estuary') in the South Hams area of Devon, England runs from Kingsbridge in the north to its mouth at the English Channel near Salcombe and lies between Bolt Head and Sharpitor to the west and Portlemouth Down to the east. The estuary is some in length, with numerous side channels. Several of its creeks have independent names, including Blanksmill, Frogmore, Southpool, Batson and Bowcombe Creek (the most northerly portion of the estuary). It covers an area of 674ha of which 446 ha are inter-tidal. At high water the length of coast within the ria is . Although there are no major water courses entering the estuary, its total catchment area is . The estuary is an extreme example of a ria or drowned valley caused by rising sea levels rather than a true estuary. Prior to the sea level rise at the end of the last glacial period, it was the valley of a river. Its size is disproportionate to the size of the small st ...

Plymouth
Plymouth () is a port city status in the United Kingdom, city and unitary authority in South West England. It is located on the south coast of Devon, approximately south-west of Exeter and south-west of London. It is bordered by Cornwall to the west and south-west. Plymouth's early history extends to the Bronze Age when a first settlement emerged at Mount Batten. This settlement continued as a trading post for the Roman Empire, until it was surpassed by the more prosperous village of Sutton founded in the ninth century, now called Plymouth. In 1588, an English fleet based in Plymouth intercepted and defeated the Spanish Armada. In 1620, the Pilgrim Fathers departed Plymouth for the New World and established Plymouth Colony, the second English settlement in what is now the United States of America. During the English Civil War, the town was held by the Roundhead, Parliamentarians and was besieged between 1642 and 1646. Throughout the Industrial Revolution, Plymouth grew as a ...

Falmouth, Cornwall
Falmouth ( ; kw, Aberfala) is a town, civil parish and port on the River Fal on the south coast of Cornwall, England, United Kingdom. It has a total resident population of 21,797 (2011 census). Etymology The name Falmouth is of English origin, a reference to the town's situation on the mouth of the River Fal. The Cornish language name, ' or ', is of identical meaning. It was at one time known as ''Pennycomequick'', an Anglicisation of the Celtic ''Pen-y-cwm-cuic'' "head of the creek"; this is the same as Pennycomequick, a district in Plymouth. History Early history In 1540, Henry VIII built Pendennis Castle in Falmouth to defend Carrick Roads. The main town of the district was then at Penryn. Sir John Killigrew created the town of Falmouth shortly after 1613. In the late 16th century, under threat from the Spanish Armada, the defences at Pendennis were strengthened by the building of angled ramparts. During the Civil War, Pendennis Castle was the second to las ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Wales
South Wales ( cy, De Cymru) is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia. A point of some discussion is whether the first element of the name should be capitalised: 'south Wales' or 'South Wales'. As the name is a geographical expression rather than a specific area with well-defined borders, style guides such as those of the BBC and ''The Guardian'' use the form 'south Wales'. In a more authoritative style guide, the Welsh Government, in their international gateway website ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern England
Southern England, or the South of England, also known as the South, is an area of England consisting of its southernmost part, with cultural, economic and political differences from the Midlands and the North. Officially, the area includes Greater London, the South East, the West Country (or the South West), and the East (sometimes referred to as East Anglia). The distinction between the south and rest of England and Great Britain is sometimes referred to as the north–south divide. With a population of nearly 28 million; and an area of , the south accounts for roughly 40% of the population of the United Kingdom and approximately 25% of its area. Definitions For official purposes, the UK government does not refer to the Southern England as a single entity, but the Office for National Statistics divides UK into twelve regions. In England, the North West, North East and Yorkshire and the Humber make up the North ("centre-north"); the West Midlands and East Midlands ( ...

Isostacy
Isostasy (Greek ''ísos'' "equal", ''stásis'' "standstill") or isostatic equilibrium is the state of gravitational equilibrium between Earth's crust (or lithosphere) and mantle such that the crust "floats" at an elevation that depends on its thickness and density. This concept is invoked to explain how different topographic heights can exist at Earth's surface. Although originally defined in terms of continental crust and mantle, it has subsequently been interpreted in terms of lithosphere and asthenosphere, particularly with respect to oceanic island volcanoes, such as the Hawaiian Islands. Although Earth is a dynamic system that responds to loads in many different ways, isostasy describes the important limiting case in which crust and mantle are in static equilibrium. Certain areas (such as the Himalayas and other convergent margins) are not in isostatic equilibrium and are not well described by isostatic models. The general term 'isostasy' was coined in 1882 by the America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
