Essequibo River
The Essequibo River (; originally called by Alonso de Ojeda; ) is the largest river in Guyana, and the largest river between the Orinoco and Amazon River, Amazon. Rising in the Acarai Mountains near the Brazil–Guyana border, the Essequibo flows to the north for through forest and savanna into the Atlantic Ocean. It has a total drainage basin of and an average discharge of . Territory near the river is argued over by Venezuela and Guyana. The river is administered by Guyana after being previously colonized by the British Guiana, British. Historically, Venezuela has claimed the Essequibo River as their most eastern border, though in practice it was under Dutch colonization of the Guianas, Dutch control. Geography The river runs through the Guianan moist forests ecoregion. The average annual rainfall in the catchment area is 2,174 mm. There are many rapids and waterfalls (e.g., Kaieteur Falls on the Potaro River) along the route of the Essequibo, and its wide estuary is dotted ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wakenaam
Wakenaam is an island of about at the mouth of the Essequibo River of Guyana. One of the largest islands (the others being Leguan and Hogg Island) in the Essequibo Islands group, it was settled at one time by the Dutch in the 18th century; the name Wakenaam is Dutch meaning "waiting for a name" and still contains old Dutch graves at various locations on the island. The island, like most other islands in the Essequibo River in Guyana, is characterized by green vegetation, blue skies and cool breeze from the Atlantic.

Leguan Island
Leguan Island is a small island situated in the delta of the Essequibo River on the coast of Guyana, South America. The island is shaped like a gull wing and is long and wide at its widest making it roughly square in area. When settlers first arrived on the island, they found many iguanas, hence the name Leguan Island (leguan is the Dutch word for iguanas). Demographics Leguan has an estimated population of 2,500 as of 2018 living in 36 demarcated villages. Settlements include Maryville, Le Bagatelle, Richmond Hill and Uniform. Villages are supported by the Leguan Neighbourhood Democratic Council. The population has declined fairly rapidly during the past decade as residents leave to settle in more urban parts of Guyana or migrate, often to the United States, Canada, the United Kingdom, or to various Caribbean islands. Leguan is primarily a rice farming and cattle rearing community, with roughly 3,000 acres devoted toward rice cultivation, 3,000 for cash crops, and another 2, ...

Mazaruni River
The Mazaruni River is a tributary of the Essequibo River in northern Guyana. Its source is in the remote western forests of the Pakaraima Mountains and its confluence with the Cuyuni River is near Bartica. As it descends from the Guiana Highlands the river runs south-east, past Issano, then northward to Bartica. The river is a source of alluvial gold. Sources The river takes source in the Roraima Plateau, three levels of sandstones and conglomerates, crowned by Monte Roraima, Mt. Roraima (). In Guyana, the two highest levels of the Roraima Plateau are known as Pakaraima, Pakaraima Mountains and Merume Mountains. The source of the Mazarunu River is in the Merume Mountains. The area is one of the very few places in the world still inaccessible. In 1992, a joint expedition of the Guyana Defence Force and Welsh Guards members was unable to reach the source of Mazaruni River, even with training, finances and equipment. Course The river drops down from each Roraima plateau throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rupununi
The Rupununi is a region in the south-west of Guyana, bordering the Brazilian Amazon. The Rupununi river, also known by the local indigenous peoples as ''Raponani'', flows through the Rupununi region. The name Rupununi originates from the word ''rapon'' in the Makushi language, in which it means the black-bellied whistling duck found along the river. Geography The Rupununi River is one of the main tributaries of the Essequibo River and is located in southern Guyana. The river originates in the Kanuku Mountains, which are located in the Upper Takutu-Essequibo region. The Rupununi River flows near the Guyana-Brazil border, and eventually leads into the Essequibo River. Throughout the flood season, the river shares a watershed with the Amazon. During the rainy season it is connected to the Takutu River by the flooded Pirara Creek, draining the vast swamps of the Parima or Amaku Lake. The region surrounding the Rupununi river is composed of mainly savannah, wetlands, forest, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as ba ...

Kaieteur Falls
Kaieteur Falls is one of the most powerful single-drop waterfalls in the world. It is located on the Potaro River in Kaieteur National Park, central Essequibo Territory, Guyana. It is 226 metres (741 ft) high when measured from its plunge over a sandstone and conglomerate cliff to the first break. It then flows over a series of steep cascades that, when included in the measurements, bring the total height to 251 metres (822 ft). While many falls have greater height or greater flow, few have the combination of height and water volume, and Kaieteur is among the most powerful waterfalls in the world with an average flow rate of 663 cubic meters per second (23,400 cubic feet per second). Kaieteur Falls is about four and a half times the height of Niagara Falls, on the border between Canada and the United States, and about twice the height of Victoria Falls, on the border of Zambia and Zimbabwe in Africa. Upriver from the falls, the Potaro Plateau stretches out to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfall
A waterfall is any point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling onto softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls since prehistory, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century, they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Rapids
Rapids are sections of a river where the river bed has a relatively steep stream gradient, gradient, causing an increase in water velocity and turbulence. Flow, gradient, constriction, and obstacles are four factors that are needed for a rapid to be created. Physical factors Rapids are hydrology, hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''waterfall#Types, cascade''. Rapids are characterized by the river becoming shallower with some Rock (geology), rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the stream bed, bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream ...
