River Ogmore
The River Ogmore ( cy, Afon Ogwr) is a river in South Wales that is popular with anglers. It runs generally from north to south from the Ogmore Vale and Gilfach Goch, past Bridgend and Ogmore. The River Ogmore rises at Craig Ogwr (527 m) in the Ogmore Valley as the Ogwr Fawr before it links with the Ogwr Fach at Blackmill. The River Llynfi, the River Garw and finally the River Ewenny in its estuary are all tributaries of the Ogmore which flows into the sea between Ogmore-by-Sea and the Merthyr Mawr sand-dunes. Geology and geography The Ogmore has two major branches in its headwaters: the which flows south through Nantymoel, Ogmore Vale and Lewistown; and joining it from the east the which flows through . After the confluence with the , they join to form the at Blackmill. Most of the headwaters flow over Carboniferous coal measures overlain by glacial drift and fluvial gravels. The valleys are reasonably broad for a small river, and many of the tributaries meandered t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridgend
Bridgend (; cy, Pen-y-bont ar Ogwr or just , meaning "the end of the bridge on the Ogmore") is a town in Bridgend County Borough in Wales, west of Cardiff and east of Swansea. The town is named after the Old Bridge, Bridgend, medieval bridge over the River Ogmore. The River Ewenny also flows through the town. The population was 49,597 in 2021. Historic counties of Wales, Historically a part of Glamorgan, Bridgend has greatly expanded in size since the early 1980s – the United Kingdom Census 2001, 2001 census recorded a population of 39,429 for the town and the 2011 census reported that the Bridgend Local Authority had a population of 139,200 – up from 128,700 in 2001. This 8.2% increase was the largest increase in Wales except for Cardiff. The town is undergoing a redevelopment project, with the town centre mainly pedestrianised and ongoing works including Brackla Street Centre redevelopment to Bridgend Shopping Centre, Rhiw Car Park redevelopment, ongoing public realm im ...

Nantymoel
Nant-y-moel or Nantymoel (meaning "stream from the bare mountain") is a village and includes the formerly separate village of Pricetown in the county borough of Bridgend, Wales on the River Ogmore, and is one of the constituent villages of the Ogmore Valley. It is bordered by the village of Wyndham to the south and by the Bwlch y Clawdd mountain to the north. History As with the rest of the Ogmore Valley, it was mainly a farming community up until the middle of the 19th century when coal mining became widespread across South Wales. The last coal mine (Wyndham/Western Colliery) closed in 1983, resulting in high unemployment at that time. Most residents today now travel to Bridgend or other larger towns for work. Politics Nantymoel is the name of an electoral ward to Bridgend County Borough Council. Prior to 1996, Nantymoel was a ward to Ogwr Borough Council, electing one councillor. Transport The A4061 road passes through the village and goes north over Bwlch y Clawdd where i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontycymer
Pontycymer, also spelt Pontycymmer, is a former mining village in Wales. It is situated in the Garw Valley, in Bridgend County Borough, about 7 miles or 11 km north of the town of Bridgend. It‘s attractions include a small Heritage railway, and minor alleged paranormal activity occurring annually where one of the main footpaths crosses the railway line. These allegations are not widely known and lack hard evidence. Name The name is Welsh: ''pont'' means "bridge" and ''cymer'' means "confluence", i.e. where two streams or rivers meet. Older signs for the village use the spelling of Pontycymmer; as with many other place names in Wales a double "mm" was historically included as an Anglicised spelling, but the modern Welsh spelling uses a single "m". Recent signage and Post Office records have now been changed to reflect the original Welsh spelling. Description At the southern (lower) end of the village, marking its boundary with Pantygog, the River Garw is joined from t ...

Afon Garw
The River Garw (''Afon Garw'' in Welsh, meaning "rugged river") runs for about 12 miles from its source in the hills north of Blaengarw to the confluence with the River Ogmore and the River Llynfi at Aberkenfig. It is one of three main tributaries of the River Ogmore which runs through the town of Bridgend. It is in Wales, United Kingdom. Course Originating in Blaengarw, it passes through the villages of Pontycymer, Pantygog, Lluest/ Braichycymer, Tylagwyn, Llangeinor, Abergarw and finally the village of Brynmenyn, where it joins the River Ogmore. Tributaries With most of the River Garw's course running along the floor of the river valley to which its name is given, it collects a number of tributary streams along the way. These streams are listed in order of confluence with the river from its uppermost point to its confluence with the River Ogmore. *Nant Cwm Gwyn *Ffynon Daren Goch *Nant Cwm gweinen *Cwm Nant Hir *Nant Gelli Wern: This brook is best known in the local a ...

Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...

Maesteg
Maesteg is a town and community in Bridgend County Borough, Wales. Maesteg lies at the northernmost end of the Llynfi Valley, close to the border with Neath Port Talbot. In 2011, Maesteg had a population of 20,612. The English translation of Maesteg is 'fair field'. Historically a part of Glamorgan, the growth of the town started with the opening of ironworks in the 1820s, and 1830s. Once a coal mining area, the last pit closed in 1985. With the decline of the coal industry and, more recently, the closure of one large factory producing cosmetics and another manufacturing vehicle components, the valley has become a residential/dormitory area for the Port Talbot, Bridgend and Cardiff journey to work areas. 11% (1,867 out of 20,702) of the town's population speak Welsh with 27.9% of 3-15 year olds speaking the language. It is one of the few areas of Wales where the traditional Mari Lwyd is still celebrated during Christmas. The community of Maesteg had a population of 17,580 in ...

Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Fluvial
In geography and geology, fluvial processes are associated with rivers and streams and the deposits and landforms created by them. When the stream or rivers are associated with glaciers, ice sheets, or ice caps, the term glaciofluvial or fluvioglacial is used. Fluvial processes Fluvial processes include the motion of sediment and erosion or deposition on the river bed. The movement of water across the stream bed exerts a shear stress directly onto the bed. If the cohesive strength of the substrate is lower than the shear exerted, or the bed is composed of loose sediment which can be mobilized by such stresses, then the bed will be lowered purely by clearwater flow. In addition, if the river carries significant quantities of sediment, this material can act as tools to enhance wear of the bed ( abrasion). At the same time the fragments themselves are ground down, becoming smaller and more rounded (attrition). Sediment in rivers is transported as either bedload (the coarser fr ...

Glacial Drift
In geology, drift is a name for all sediment (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by glacial meltwater. Drift is often subdivided into (unsorted and) unstratified drift (glacial till) that forms moraines and stratified drift (glaciolacustrine and fluvioglacial sediments) that accumulates as stratified and sorted sediments in the form of outwash plains, eskers, kames, varves, and so forth. The term drift clay is a synonym for boulder clay. Both are archaic terms for glacial tills with a fine-grained matrix.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds., 2005. ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. In the United Kingdom, drift is also applied as a general term for all surficial, unconsolidated, rock debris and sediment that is moved from one place to accumulate in another and mapped separately or otherwise diffrerentiated from underlying bedroc ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

River Ogmore - Bridgend - Geograph
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 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. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...
