Problem:Context: The River Severn (Welsh: "Afon Hafren", Latin: "Sabrina") is the longest river in the United Kingdom, at about . It rises at an altitude of on Plynlimon, close to the Ceredigion/Powys border near Llanidloes, in the Cambrian Mountains of mid Wales. It then flows through Shropshire, Worcestershire and Gloucestershire, with the county towns of Shrewsbury, Worcester and Gloucester on its banks. With an average discharge of at Apperley, Gloucestershire, the Severn is the greatest river in terms of water flow in England and Wales., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Abergavenny (archaically "Abergafenni" meaning "Mouth of the River Gavenny") is a market town in Monmouthshire, Wales. It is located west of Monmouth on the A40 and A465 roads, from the English border. Originally the site of a Roman fort, Gobannium, it became a medieval walled town within the Welsh marches. The town contains the remains of a medieval stone castle built soon after the Norman conquest of Wales. The town hosted the 2016 National Eisteddfod of Wales., Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides., Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is HO, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity., The English Channel ("the Sleeve" [hence ] "Sea of Brittany" "British Sea"), also called simply the Channel, is the body of water that separates southern England from northern France, and joins the southern part of the North Sea to the rest of the Atlantic Ocean., An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word "archipelago" is derived from the Greek "-  arkhi-" ("chief") and "  pélagos" ("sea") through the Italian "arcipelago". In Italian, possibly following a tradition of antiquity, the Archipelago (from medieval Greek "*" and Latin "archipelagus") was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to refer to any island group or, sometimes, to a sea containing a small number of scattered islands., The tidal range is the vertical difference between the high tide and the succeeding low tide. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. The tidal range is not constant, but changes depending on where the sun and the moon are., Pen y Fan is the highest peak in south Wales, situated in the Brecon Beacons National Park. At above sea-level, it is also the highest British peak south of Cadair Idris in Snowdonia. The twin summits of Pen y Fan and Corn Du at 873 m (2,864 ft) were formerly referred to as Cadair Arthur or 'Arthur's Seat'., A high water mark is a point that represents the maximum rise of a body of water over land. Such a mark is often the result of a flood, but high water marks may reflect an all-time high, an annual high (highest level to which water rose that year) or the high point for some other division of time. Knowledge of the high water mark for an area is useful in managing the development of that area, particularly in making preparations for flood surges. High water marks from floods have been measured for planning purposes since at least as far back as the civilizations of ancient Egypt. It is a common practice to create a physical marker indicating one or more of the highest water marks for an area, usually with a line at the level to which the water rose, and a notation of the date on which this high water mark was set. This may be a free-standing flood level sign or other marker, or it may be affixed to a building or other structure that was standing at the time of the flood that set the mark., Yr Wyddfa commonly known as Snowdon in English, is the highest mountain in Wales, at an elevation of above sea level, and the highest point in the British Isles south of the Scottish Highlands. It is located in Snowdonia National Park (") in Gwynedd, and has been described as "probably the busiest mountain in Britain".

With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., Monmouthshire is a county in south east Wales.

Other towns and large villages are Caldicot, Chepstow, Monmouth, Magor and Usk., The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea., Egypt (; ', , "Kimi"), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. Egypt is a Mediterranean country bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba to the east, the Red Sea to the east and south, Sudan to the south, and Libya to the west. Across the Gulf of Aqaba lies Jordan, and across from the Sinai Peninsula lies Saudi Arabia, although Jordan and Saudi Arabia do not share a land border with Egypt. It is the world's only contiguous Afrasian nation., The Severn Estuary is the estuary of the River Severn, the longest river in Great Britain. It is at the mouth of four major rivers, being the Severn, Wye, Usk and Avon, and other smaller rivers. Its high tidal range of about means that it has been at the centre of discussions in the UK regarding renewable energy., The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, with an area of around ., Monmouth (; Welsh: "Trefynwy" meaning "town on the Monnow") is a traditional county town in Monmouthshire, Wales.

The most densely populated region in the southwest of the United Kingdom, it is home to around 2.2 million people. The region contains almost three-quarters of the population of Wales, including the capital city of Cardiff (population approximately 350,000), as well as Swansea and Newport, with populations approximately 240,000 and 150,000 respectively. The Brecon Beacons national park covers about a third of South Wales, containing Pen y Fan, the highest mountain south of Snowdonia., Cardiff is the capital and largest city in Wales and the eleventh-largest city in the United Kingdom. The city is the country's chief commercial centre, the base for most national cultural and sporting institutions, the Welsh national media, and the seat of the National Assembly for Wales. The unitary authority area's mid-2011 population was estimated to be 346,100, while the population of the Larger Urban Zone was estimated at 861,400 in 2009.

In 2011, Cardiff was ranked sixth in the world in National Geographic's alternative tourist destinations., The Brecon Beacons is a mountain range in South Wales. In a narrow sense, the name refers to the range of Old Red Sandstone peaks which lie to the south of Brecon. Sometimes referred to as "the central Beacons" they include South Wales' highest mountain, Pen y Fan. The range forms the central section of the Brecon Beacons National Park ("Parc Cenedlaethol Bannau Brycheiniog"), a designation which also encompasses ranges both to the east and the west of "the central Beacons". This much wider area is also commonly referred to as "the Brecon Beacons", and it includes the Black Mountains to the east as well as the similarly named but quite distinct Black Mountain to the west. The highest peaks include Fan Brycheiniog to the west and Pen y Fan in the central part. They share the same basic geology as the central range, and so exhibit many similar features, such the north-facing escarpment and glacial features such as lakes and cwms below the escarpment. They all fall within the border of the national park., West Wales is the western region of Wales.  Some definitions of West Wales include only Pembrokeshire, Ceredigion and Carmarthenshire, which historically comprised the Welsh principality of "Deheubarth" and was called "South West Wales" in the Nomenclature of Territorial Units for Statistics (NUTS). Other definitions include Swansea and Neath Port Talbot but exclude Ceredigion. The "West Wales and the Valleys" NUTS area includes more westerly parts of North Wales. The preserved county of Dyfed covers what is generally considered to be West Wales, which, between 1974 and 1996, was also a county, with a county council and six district councils., Brecon, archaically known as Brecknock, is a market town and community in Powys, Mid Wales, with a population in 2001 of 7,901, increasing to 8,250 at the 2011 census.

Its rocky southern foreshore marks the boundary between England and Wales . Above high water mark , the island is reckoned administratively to Monmouthshire , South Wales . The island also marks the north - western limit of the City of Bristol 's water boundary in the Severn estuary . It is located approximately three miles north of Portishead , midway between Redwick in Wales and Avonmouth in England . It is surrounded by sandbanks known as the Welsh Grounds . Its foreshore area changes dramatically according to the state of the tide , because tides in the estuary and Bristol Channel are the second highest in the world , reaching 13.7 m ( 45 ft ) at the spring equinox . It is known as a nesting - place for gulls , cormorants and other seabirds , which are regularly seen and ringed there ., Mid Wales (or simply "Y Canolbarth" "The Midlands") is the name given to the central region of Wales. The Mid Wales Regional Committee of the National Assembly for Wales covered the counties of Ceredigion and Powys and the area of Gwynedd that had previously been the district of Meirionydd. A similar definition is used by the BBC. The Wales Spatial Plan defines a region known as "Central Wales" which covers Ceredigion and Powys. If Mid Wales is classed as Ceredigion and Powys, the area would be 6,962 square kilometres (about the size of Cumbria)., Chepstow is a town in Monmouthshire, Wales, adjoining the border with Gloucestershire, England.

The chairman of the new region is Sir Terry Matthews., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., The Philippines, officially the Republic of the Philippines, is a sovereign island country in Southeast Asia situated in the western Pacific Ocean.

Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, e.g. the Philippines., A continent is one of several very large landmasses on Earth. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
